Heavy Duty Disposable Panel Filters

Spun Glass Media - Model 10255.xxxxxx

Synthetic Media - Model 11255.xxxxxx

General

Flanders HD Industrial Grade filters are designed

for use in any application where disposable panel

filters are recommended. They can be relied upon

for superior performance since they are specifically

designed for heavy workloads. A wide range of

standard face sizes is available, plus nearly any

“special” size.

Construction

Flanders HD Industrial Grade filters are designed

with a one-piece moisture-resistant chipboard

frame enclosing media. Standard frames are nomi-

nal 1” thick (3/4” actual) and nominal 2” thick (1-5/8”

actual).

The fiberglass media filter consists of continuous-

filament fibers bonded together with thermo-setting

resin. The synthetic media filter consists of 100%

high bulk polyester fibers that are thermo bonded

with a fire retardant resin.

Support grilles of perforated corrosion-resistant

steel or expanded metal are provided on both sides

of the filter. The media pads and support grilles are

continuously glued to the inside perimeter of the

frame, resulting in exceptional strength and rigidity.

This design virtually eliminates the possibility of

media sag within the frame.

Physical Data

EZ Flow and EZ Flow II

Disposable Panel Air Filters

EZ Flow - Model 10155.xxxxxx

EZFlow II - Model 10055.xxxxxx

General

EZ Flow and EZ Flow II disposable filters are

designed for protection of furnace and central air

units in residential and light commercial applica-

tions. Construction of both models is identical

except for the media retainer. The EZ Flow features

a metal media retainer on the downstream side

while the EZ Flow II has no media retainer. Instead,

the media itself is adhered directly to the frame for

non-metallic applications.

Construction

The frame is made from heavy chipboard in a one-

piece design that eliminates corner separation.

The filtering media is continuous filament spun

glass. A resinous bonding agent provides rigidity

and resistance to media compression.

MEDIA SUPPORT of the EZ Flow is provided by

one metal retainer on the downstream side, either

punched metal plate or expanded metal, depending

on face size. The EZ Flow II is made to function

without a retainer, by adhering the frame directly to

the media which has a light skin to make it self-

retaining.

SEALING is accomplished with a resilient hot-melt

adhesive running the full perimeter of the frame on

both upstream and downstream sides.

UL MARKING appears on the filter frame. These fil-

ters have been tested by Underwriters Laboratories

Inc. and are classified as UL 900 Class 2 for flam-

mability.

Important Features

• One-piece frame

•UL900 Class 2

• UPC marked

• No media retainer on EZ Flow II

•Metal media retainer on EZ Flow

•1/2”, 1” and 2” depths

Pinch Frame

Disposable Panel Air Filters

Model 11655.xxxxxx

General

The Flanders Pinch Frame disposable air filter pro-

vides the user with a product of high quality and

strength.

Originally designed for light commercial and indus-

trial applications, the Flanders Pinch Frame filter is

an excellent choice for use in residential furnace

systems.

The filter is produced on state-of-the-art production

line machinery. The result is a filter of consistently

high quality at a competitive price.

Construction

This disposable heating and air conditioning filter

has a one-piece chipboard frame. This feature elim-

inates the problems associated with a four-piece

frame, such as broken corners and exposed metal

edges.

The Pinch Frame filter utilizes a heat seal to bond

the frame to the filter media and metal support grid.

This process permits the use of a single metal grid

on the air exit side only, thus maximizing filter face

area and extending service life.

The media is made of 100% nonwoven polyester

synthetic fibers chemically bonded with a fire retar-

dant resin. Because of the synthetic nature of the

fiber, the media is extremely resistant to moisture

and other environmental extremes.

Physical Data

Frame: One-piece chipboard

Rugged, Heat-sealed,Construction

Flanders Ring Panel and

Cube filters are made by

heat sealing layers of syn-

thetic filtering media

together over an interior,

corrosion-resistant steel

support frame. An overcut

of media outside the seal-

forms a built-in gasket

(selvage) between the

wire support frame and

holding frame, which secures the filter and prevents

air bypass. This special feature allows these filters

to be installed without the use of retainer fasteners

Link Panels

Flanders Ring Panel filters can be ordered as stan-

dard single panels or as link panels. A link panel is

made by heat sealing individual Ring Panel filter

panels end to end to achieve desired dimensions.

Sleeve Panels

Sleeve Panels are nearly identical to the stan-

dard Ring Panel. The only major difference in

construction with the Sleeve Panel is that one

end is left unsealed. Therefore, the interior sup-

port frame can be removed and used over and

over again, with just the soiled media thrown

away. This is more economical and makes dis-

posal easier.

Cubes

Cubes are internally supported filters similar to the

Polyester Panel. The exception is greater surface

area for contamination capture. Unitary, 2-pocket or

3-pocket construction is available throughout our

entire product offering. Cubes are available with

13/16” thick headers for side access installations or

other systems where a header is required.

A Moisture-resistant Alternative

Because these filters are made with only metal and

synthetic materials, they are an excellent alterna-

tive to paper-frame filters in high moisture areas

because they are naturally moisture-resistant and

will not deteriorate or warp in wet or humid condi-

tions.

Paintbooth Filtration

Downdraft

Prep Station

Crossdraft

Flanders offers a wide variety of filtration products for

downdraft and crossdraft paintbooths and prep sta-

tions. For the most part, fitlration products required for

all of these fall into three general categories which are

color coded to the drawings at left which indicate their

placement in each type of booth.

Air Intake filters are as important to a great paint job

as the booth itself. The intake filters are the primary

defense against foreign particles landing on the paint-

ing surface. Any particle larger than 10 microns can

cause a defect on a paint job. Intake filters are typi-

cally either panels or pads. Intake filters in a down-

draft booth and prepstations are above the painting

surface. In crossdraft booths, they are typically in the

door.

Exhaust filters play an important role in maintaining

proper air flow balance, increasing cleanliness of

exhaust stacks, reducing maintenance of the exhaust

system and in controlling V.O.C. emissions. The pur-

pose of exhaust filters is to capture overspray parti-

cles and remove them from the airstream as air is

removed or recirculated back into the booth.

Crossdraft and semi-downdraft booths use media

pads which are placed on grids in the rear wall or

lower portion of the side walls in filter housings.

Downdraft booths use a long pad that is placed into a

pit below the painting surface.

Aprefilter is designed to filter out large particles

before the air reaches the intake filter. This prolongs

the life of the intake filter, increases airflow in your

booth and reduces maintenance costs on the intake

stack and mechanical parts. The prefilter is typically

found only in heated booths. Crossdraft booths will

very rarely have a prefilter. In downdraft and semi-

downdraft booths, the prefilter is located somewhere

along the duct-work bringing air into the booth.

SA600-G10 Diffusion Media for Air Intake

Models SA600-xxx

For downdrafts and prep stations. This filter pro-

vides the highest level of protection against paint

damaging particles available today. In addition to

its leading reputation in filtering ability, the SA600-

G10 is able to withstand high temperature applica-

tions, up to 140 degrees Celcius! This filter does

not discolor or break down in the heated booth

environment. Other leading media using traditional

tackifiers and PVC resins, produce a heavy discol-

oration and the media expands reducing the filter-

ing ability.

Flanders’ re-engineered media and manufacturing

process has virtually eliminated these flaws. Using

ecologically sound materials, and eliminating PVC

resins, the media discoloration and media expan-

sion have been minimized. The SA600-G10 is a 1”

diffusion media, and carries the prestigious G10

mark. G10 is a European standard for test per-

formance, and only qualified media can claim this

mark of distinction. It has a high dust holding

capacity for long life, and stops all particles of paint

damaging size from entering a paintbooth when

installed properly.

This product has a normal service life of 10 to 18

months, depending on outside air quality and

usage. The filter is available in bulk rolls or cut

pads for your convenience. Cut pads are cut in our

facility to your booth requirements.

SAR-1 Pad for Air Intake

Models SAR1M-xxxxx

For use as an intake blanket on crossdraft booths.

The SAR-1 media, made in Switzerland, has a 1/2“

loft, and is optimally designed for efficiency and

dust holding capacity. For crossdraft booths, the

SAR-1 pad, sometimes referred to as a blanket, is

tucked into the doors of the booth. There is usual-

ly only one large pad on each door. Oversized

SAR-1 media pads can be easily trimmed.

The SAR-1 media is a premium choice for cross-

draft requirements. The tackifier and heavily cal-

lendered exit side allow for excellent particle reten-

tion. The SAR-1 is a premium choice for crossdraft

filtration.

SAR-1 Panels for Air Intake

Model SAR1Pxx-xxxx

For use in crossdraft and some downdraft

booths.The SAR-1 PANEL, made in Switzerland, is

a premium choice for panel filtration. The SAR-1

PANEL is made from two media pads. A metal

support is dielectrically heat sealed in between the

two media layers providing support and rigidity.

The first media layer is designed to catch large par-

ticles entering the booth. The second media layer

is designed to catch the smaller particles. 100% of

the fibers in the second layer are tackified to retain

trapped particles. The combination of small fiber

size and a callendered exit provide unsurpassed

R-1 filtration.

The metal support is made from 9 gauge galva-

nized steel, which will not rust. The support is

formed into a rectangular shape and contains two

crossbars for added stability.

When choosing the correct size, measure the metal

support. The metal support will be 3/8” under the

listed size. For instance, a 20x20 panel’s ring will

measure 19-5/8 x 19-5/8. Crossdraft booths will

have a series of housings that look like square or

rectangular holes in the booth doors. Panel filters

have extra media overlapping the metal support

which act as gasketing when placing the panel filter

inside the housing and create a tight seal to prevent

any air bypass around the filter.

Series ST55 Panel for Air Intake

Models ST55R-xxxx and ST55L-xxxx-xx

The SERIES ST55 PANEL, made in the USA, is an

economical choice for crossdraft booths. The

SERIES ST55 is made from two media pads. A

metal support is dielectrically heat sealed in

between the two media layers, providing support

and rigidity.

The first media layer is designed to catch large par-

ticles entering the booth. The second media layer

is designed to catch the smaller particles. The

downstream side of the second layer is treated with

a sticky non-migrating tackifier which holds trapped

particles inside the filter. The metal support is

made from 9 gauge galvanized steel, which will not

rust. The support is formed into a rectangular

shape and contains two crossbars for added stabil-

ity.

When choosing the correct size, measure the metal

support. The metal support will be 3/8” under the

listed size. For instance, a 20x20 panel’s ring will

measure 19-5/8 x 19-5/8.

Series 332 Paint Arrestor

Models 332PA-xxxx

Fiberglass with polyester for use as a paint arrestor

in all types of booth. Series 332 is our highest qual-

ity fiberglass media available. Made with 18 grams

of fiberglass per square foot, and a polyester exit

layer, the Series 332 is more efficient and holds

more paint than almost any other fiberglass prod-

ucts.

Series 332 comes in 200 ft. rolls and in pads for

crossdraft and semi-downdraft booths. Series 332

is made from air-laid fiberglass forming a 2.5”

thickness and a thin polyester layer bonded to the

exit side for added efficiency.

Series 332 fibers are ideal for paint capture due to

their loose weave. The paint particles collide with

the fiberglass fibers and are removed from the

airstream, and the fine particulate is removed by

the polyester exit layer.

Agrid is needed to hold the pad which is standard

in most booths, or are available through Flanders

customer service.

If your downdraft booth uses a pit, measure the

width of the pit to find the appropriate roll, or check

our booth guide. To change the media, simply,

unwind the roll to the proper length, and cut a pad.

FP3-Paint Arrestor

FP3PA-xxxx

FP3 media is an excellent choice for exhaust media

in any booth. Use of this media will keep the booth

exhaust system cleaner when converting from

fiberglass, however some older booths do not work

well with the resistance levels.

FP3 media combines three distinct layers of poly-

ester fibers forming a funnel effect. The first layer

captures large particles. The second and third lay-

ers catch the finer particles.

By utilizing an open weave on the first layer, parti-

cles do not cause the filter to quickly clog up allow-

ing large amounts of paint to be captured without

substantial increases in air pressure.

The pad sizes listed below are typical in crossdraft

and semi-downdraft booths. If converting from

Styrobaffle or Styrofoam, grids will be needed to

hold the pads in place. If your downdraft booth

uses a pit, measure the width of the pit to find the

appropriate roll, or check our booth guide.

holds more paint than many other fiberglass prod-

ucts. It comes in 200 ft. rolls and is also available in

pads for crossdraft and semi-downdraft booths.

Series 331Y is made from air-laid fiberglass form-

ing a 2.5” thickness. The exit side has a skin back-

ing for added efficiency.

Series 331Y fibers are ideal for paint capture due to

their loose weave. The paint particles collide with

the fiberglass fibers and are removed from the

airstream.

If your downdraft booth uses a pit, measure the

width of the pit to find the appropriate roll, or check

our booth guide. To change the media, simply,

unwind the roll to the proper length, and cut a pad.

Series 330G PA

Models 330G-xxx

15 gram Fiberglass Paint Arrestor for all booth

types. Series 330G is our economy grade fiber-

glass media. Made with 15 grams of fiberglass per

square foot, the Series 330G holds more paint than

other economy fiberglass media due to its skin exit

side.

Series 330G comes in 100 ft. rolls compared to

many of our competitors 200-300 ft. rolls. The fiber-

glass is also available in pads for crossdraft and

semi-downdraft booths.

Series 330G is made from air-laid fiberglass form-

ing a 2.5” thickness. The exit side has a skin back-

ing for added efficiency.

Series 330G fibers are ideal for paint capture due to

their loose weave. The paint particles collide with

the fiberglass fibers and are removed from the

airstream.

If your downdraft booth uses a pit, measure the

width of the pit to find the appropriate roll, or check

Series 225T Cube

Models CUBx225Txxxxxx

2-Ply Self Supportive Cube Filter for use as a paint

arrestor. 225T Cube filters are a single pocket

trapezoid cube filter. A 1” dual denier polyester

media is sewn into shape. The filter is then

attached to a 9 gauge wire for support when

installed in the filter housing.

Due to their unique design, cube filters have a larg-

er surface area than conventional pads. The

increase in surface area allows the filter to hold

more contaminants thereby increasing the life of

the filter.

325Tand 425T-Cubes

Models CUBx325Txxxxxx and CUBx425Txxxx

Three and Four Stage Cube Filters for use as a

paint arrestor. Two products make up our premium

exhaust cube product line. They are the Series

Flanders - Foremost in Air Filtration

the filter and hvac store

Flanders - Foremost in Air Filtration

Corporate Headquarters, St. Petersburg, FL

325T, which is 98% efficient, and the Series 425T

which is 99% efficient. The exhaust cube filters

have a larger surface area than a conventional flat

pad. This increase in surface area reduces the

restriction to airflow, and increases the paint hold-

ing capacity of the filter. This means better airflow

and longer life.

The Series 325T is made from a polyester media

supported by a 9 gauge wire frame. The dual

denier media is used as an initial barrier, and a

tightly woven thin media is used as a final particle

barrier. This filter captures an average of 98% of

overspray in weight.

The Series 425T has an added layer of media

applied to the downstream side of the filter.

Although the construction is the same as the Series

325T, the added layer of single denier polyester

fibers gives the Series 425T a 99% efficiency rat-

ing.

PS125-Bag

Models 125BAG-xxxxxx

Scrim-Back Polyester Media Bags for use as a sec-

ondary paint arrestor in selected booths.

Each bag is hand sewn and attached to a 9 gauge

galvanized support frame, and includes a 1” head-

er for easy placement in side access housings.

Special bags may require a wire support basket, no

header or frame, or loops at the end of each pock-

et for support.

The media is a 1” single denier polyester fiber with

a scrim backing. This media has little effect on the

airflow, and has a high dust holding capacity. The

unique pocket design increases the surface area of

the media. This increase in surface area will

increase the life of the filter, and reduce the pres-

sure drop.

If the exhaust bag is the same size as a booth’s

intake bags, it is common to rotate the intake bags

to the exhaust bags to reduce costs. Bag meas-

urements are nominal in size. If a bag is 15.5” x

24.5” x 19.5”, the listed size is 16” x 25” x 20”.

Please note this difference when measuring your

exhaust bags.

Andrea and PS125 Exhaust Filters

Models ANDREA and 125PAD-xxxx

The Andrea filter is a paper paint arrestor with a

unique design. Kraft paper is pleated into an accor-

dion-like form with holes punched in the paper at

consistent intervals. A second layer of paper is

attached to the back with different hole placements.

When air passes through the filter, it hits the wall of

the second kraft paper layer and is diverted through

the second hole. This air turbulence and laws of

motion cause the paint to collect on the paper and

cleaned air to pass through the filter.

The PS125 Water Wash Pads are designed specif-

ically for use in select Spraybake brand booths.

Certain models of Spraybake use a water wash

system as a secondary exhaust. This water wash

system requires special pads to be used to filter out

particulate in the system. The fiber has a reinforced

scrim backing on the downstream side to prevent

fiber breakoff or migration. The water wash pads

are also available in custom sizes.

*Our filters are not affiliated with SPRAYBAKE®. Use of the

registered SPRAYBAKE® name is for comparative purposes

Models 225RT-xxxx and 225LT-xxxxx-xx

2-ply Panel and Link Filter for use as a prefilter in

downdraft booths. The 2 ply panel filters are con-

structed using two layers of poly-synthetic fibers.

These layers are designed to capture large parti-

cles in the first layer and smaller particles through-

out the second layer.

A9 gauge wire frame with two cross pieces is

dielectrically heat sealed inside the filter for sup

the filter and hvac store

port. The media overlaps the support, which pro-

vides a gasketing effect reducing air bypass around

the filter.

Atackifier is applied in between the last two layers

to stabilize any migrating particles and prevent the

discharge of particles from the filter. The graduat-

ed media design produces a superior dust holding

capacity that will outlast most filters on the market.

Panel filters are 100% moisture resistant and will

not warp or deteriorate in wet or humid conditions.

By utilizing one continuous panel in a filter track,

and its selvedged edge, a panel filter eliminates air

bypass so common among cardboard framed fil-

ters.

When measuring the correct filter for your booth,

first measure the entire filter track. This measure-

ment should have a track height of 14-25” and a

length of 14-100”. The height of the 2 Ply Panel is

listed as a nominal size. For instance, if a filter ring

measures 15.5” x 19.5”, then the correct size is 16”

x 20”. There are hundreds of standard sizes avail-

able. Custom sizes are also available.

Model 40 Standard Capacity Pleat

Models 80055.xxxxxx

For use as a prefilter in downdraft booths. Model 40

Pleats are designed to operate in almost every type

of installation. Available in 1”, 2” and 4“ nominal

thicknesses, these filters have an average atmos-

pheric dust spot efficiency range of 25-30% per

ASHRAE Standard 52.1 test methods. Model 40

Pleats offer greater efficiency and service life than

disposable filters, pad and frame systems, or metal

washable filters. The overall design of this product

makes these filters the accepted choice in applica-

tions requiring high performance and extended

service.

Filter frames are constructed from two pieces of

die-cut, moisture-resistant carrier board.

Components”telescope” into one another and pro-

vide double-wall construction and a precision fit.

The frame includes diagonal and horizontal support

members bonded to the media on the air entering

and leaving sides for unsurpassed frame strength,

locking corners and positive media-to-frame seal

reduces the possibility of air bypass.

The filter is made from fully synthetic, high-loft and

reinforced media. It is continuously laminated to an

expanded metal grid on the air leaving side to pro-

vide pleat stability throughout the life of the filters

and prevent media flutter while in operation. The

unique v wedge allows for total media usage and

provides maximum air flow.

Precision Pak

Models PAPxxxSxxxx

High efficiency bag filter for use as a prefilter in

downdraft booths and prep stations.

The Precision Pak ASHRAE bag use a fully syn-

thetic media that provides an efficiency rating of 45-

55%. The pockets are hand sewn or ultrasonically

sealed and fastened to an all aluminum frame.

They are designed for specific booths and prep sta-

tions that can accommodate their special size and

performance properties. UL 900 Class 2 Listed.

Precision Pak bags have a large amount of media

surface area. This decreases the pressure drop

and increases the capacity. These bags hold sub-

stantial amounts of dirt removed from the airstream.

Use of these bags will ensure a clean environment

throughout the intake stack and prolonged life of

the ceiling diffusion media.

Bag filters are sized nominally in their length and

width. If the booth track measures 19.5” x 19.5”,

then the correct bag listed is 20” x 20”. Bag filters

also have a special depth. The depth describes the

length of the pockets. This is an exact size and is

usually an even number. There are many other

sizes available, and custom sizes can be made to

order. There are also other efficiencies ranging

from 45% through 95%. For additional sizes, UL

Ratings or efficiencies, please contact customer

FP319A Chromate Recovery System

The Flanders FP319A-Chromate Recovery System

is offered in both two-stage and three-stage config-

urations for aerospace overspray painting environ-

ments.

The FP319A complies with EPA (Environmental

Protection Agency) Test Method 319 as it applies to

the National Emissions Standards for Hazardous

Air Pollutants (NESHAP). Reference 63 Fed. Reg.

59 (March 27, 1998) and 40 C.F.R. 9, 63.

The EPA Test Method 319 is a testing protocol in

which potassium chloride and oleic acid are substi-

tuted for chromate paint. These chemical sub-

stances attempt to simulate dry and wet overspray

characteristics of the chromate paint. This testing

protocol verifies that an air filtration system (two or

three-stage) has met minimum efficiency require-

ments, under laboratory conditions, utilizing potas-

sium chloride and oleic acid.

The Flanders FP319A two and three-stage systems

have been qualified by independent laboratory on

specific chromate paints. These tests are per-

formed in controlled environments to simulate the

“real world” painting environment.

Service Rolls

Flanders Service Rolls air filtration media are man-

ufactured in selected widths, prepared in roll

lengths that make manageable roll sizes. In most

cases, a single cut across the roll will produce a

ready-to-install filter pad.

The following media are offered as service rolls:

Spun Glass: (Models SGxxxxKK) This is a rigid, nominal

3/8” thick, dry spun glass. It is typically used to

make rigid pads for use in room unit air condition-

ers. It is designed for use without a frame. Since it

is untreated, it will not harm the plastic frequently

used in the construction of room units.

Foam: (Models FRxxxxx) Arugged polyurethane foam

that is designed for use in room unit air conditioners

and in pad-holding frames. It is washable and will

withstand repeated cleaning with mild soap and

water. Foam service rolls are available in 1/4”, 1/2”,

1” and 2” media thicknesses. They are washable for

repeat use.

Aluminum: (Models EAxx) The aluminum service roll is

an expanded aluminum mesh of the type used in

room unit air conditioners. It is a nominal 1/4” thick

dry filter media that requires the addition of a dust

adhesive for effective filtration.

Kwik Kuts

(Models KKxxx)

These are 15”x24” pads of filter media that can be

easily cut to fit any window or wall mounted room

air conditioner. They are offered in the same spun

glass, foam and aluminum media described above.

Also offered are 1/2” Permaire (see column at

right) and plastic-backed foam.

Hammock Rolls and Pads

Models HRxxxx

Flanders hammock rolls are available in nominal 1”

spun glass, 2” spun glass, and 1” polyester syn-

thetic fiber media. Performance data on all

Flanders hammock media is available upon

request.

Typically, these are for Lennox type furnaces.

(Lennox is a brand name. It is used here for system

identification only.) Hammock rolls are 20 foot rolls

of media cut in various widths. In most cases, a sin-

gle cut across the roll will produce a ready-to-use

filter pad. Flanders hammock rolls are packaged in

a handy carton that can be used as a dispenser.

Media used in all Flanders hammock rolls are UL

Class 2 fire rated. The 1” spun glass is also avail-

able in pre-cut hammock pads, individually pack-

aged in plastic

Permaire Rolls and Pads

Models HHxxxx

Permaire is a unique type of air filtration media that

has evolved from a natural organic fiber media to a

new completely synthetic, self-supporting and com-

pletely washable media. It has all the benefits of

organic media but has a longer service life, better

structural integrity as well as being completely odor

free. It is made of synthetic fibers and coated with a

special resin, then baked together at a high tem-

perature. The result of this process is a tough and

springy, thoroughly bonded, nearly rigid air filtration

media.

Describing Permaire as merely an air filtration

medium is telling only half of the story. Due to its

natural rigidity, a pad of Permaire cut to the proper

dimensions is actually a complete filter ready to

install. It is totally self supporting. With nothing

more than Permaire and a hefty pair of scissors or

a razor knife, you can replace almost any size 1/2”,

1” or 2” framed panel filter.

Permaire filters are passive electrostatic type prod-

ucts. Air running over the maze of fibers creates an

electrostatic charge to catch and hold airborne con-

taminants. Dust particles may become charged nat-

urally, and if so, they are held by strong electrostat-

ic forces to the oppositely charged fiber with which

they come into contact. The smaller a particle or

fiber, the relatively stronger the electrostatic

charges will be attained. Dirt loads throughout the

filter’s depth and therefore it will hold a lot more

dust than other filters before requiring changing or

cleaning.

Permaire is an ideal product for filter service pro-

fessionals. With a roll of Permaire on your truck,

you can replace almost any size panel filter. It’s a

perfect answer to “odd” size filters. A 10x32”special”

is as close as a pair of scissors...and the same low

cost as a 16x20 standard that you cut from the

same roll.

Wide selection of media types

Flanders offers a wide range of top quality air filtra-

tion media available in bulk rolls and pads.

Considering the unique characteristics of each

offering, the user can get maximum value for filter

dollar spent with relation to the intended use.

Bulk media rolls are offered in selected slit widths

with roll lengths determined by manufacturing

processes. Pre-cut pads, as the name implies, are

pads of filtration media cut to standard filter face

sizes or to your desired custom sizes.

Spun glass is a rugged industry standard, known

for low resistance while providing excellent

arrestance and high dust holding capacity. They are

designed to trap dirt throughout their thickness. A

resinous bonding agent in the media increases

rigidity and resistance to compression so the filter

will not collapse in the airstream. Flashpoint is 325

degrees Fahrenheit on the treated adhesive.

Spun Glass

7/8”Blue Production Glass (Models GMxx) Nominal 7/8”

adhesive-treated spun glass. For residential or light

industrial and commercial air filtration. Commonly

Principles of Operation

Flanders’ v-pleat design insures that the greatest media area is exposed to the air flow to promote uniform

dust loading. Competitive filters cannot maintain this rigid shape and tend to flatten out, using only a por-

tion of the media. This v-pleat design creates an air exit area (B) equal to the air entering area (A), which

minimizes end losses and reduces pressure drop.

Radial wedge pleats have unequal air exit (D) and air entering (C) areas, which cause higher resistance and

uneven use of media.

Construction

Filter frames are constructed from two

pieces of die-cut, moisture-resistant

carrier board. Components “tele-

scope” into one another and provide

double-wall construction and a preci-

sion fit. The frame includes diagonal

and horizontal support members

bonded to the media on the air enter-

ing and leaving sides for unsurpassed

frame strength. Locking corners and

positive media-to-frame seal reduces

the possibility of air bypass.

The filter media is a high-loft, rein-

forced, non-woven cotton/synthetic

blend. It is continuously laminated to

an expanded metal grid on the air

leaving side to provide pleat stability

throughout the life of the filters and

prevent media flutter while in opera-

tion.

Flanders’ unique v-pleat wedge pleat

allows for total media usage and pro-

vides maximum air flow and dust hold-

ing capacity.

Filtration for IAQ

Flanders Pre Pleat 62R pleated panel air filter was

specifically designed to improve indoor air quality

through a new level of particulate filtration. The fil-

ter takes its name from the ASHRAE Standard 62

which addresses indoor air quality. The Pre Pleat

62R is indeed state of the art.

Electrostatically Charged Media

The Pre Pleat 62R features a 100% synthetic elec-

trostatically charged filtration media, which actively

attracts and holds airborne contaminants. The filter

media is bonded to a corrosion resistant expanded

metal backing. This combination is then folded into

an accordian pleat arrangement and sealed within

a moisture resistant frame.

The Pre Pleat 62R is more efficient when compared

to standard pleated filters and has a high dust hold-

ing capacity that does not sacrifice airflow. Initial

resistance of a 2 in. deep filter is just 0.3 in. w.g. at

500 fpm. Dust holding capacity of a 24x24x2 in.

high capacity filter is 181 grams at 1 in. w.g. final

resistance.

re Pleat 62RM11 pleated panel filter enables

a significant upgrade in collection efficiency

over existing MERV 8 products at the same

resistance levels. From 30-35% to 60-65%

average per Ashrae 52.1-1992 average

dust spot efficiency at nearly the same

pricing levels.

Bi-component media: Our next-gener-

ation ultra-high performance bi-component

synthetic media contains mechanically engi-

neered tri-lobal fibers with inhomogenous domains

of positive and negative Electret charges within the

bi-component fibers to equal an ultra-high perform-

ance product.

Enhanced fibers: Mechanically and electrostatical-

ly enhanced fibers are precisely structured into a

progressive density gradient structure to enhance

airflow throughput with less resistance while pro-

viding high dust holding capacity and ultra-high effi-

ciency during operational life.

Gradient media structure: Proprietary

"Engineered Gradient Media Structure" enables

larger incoming contaminants to be trapped in the

pre-filter layer thus allowing the highly charged sec-

ondary layer to attract and hold smaller particulate,

thereby increasing the life of more expensive final

filters downstream.

High efficiency at low pressure drop: This propri-

etary media combined with Flanders’ unique V-

Pleat manufacturing design equals the highest per-

formance pleat available on the market today. The

proprietary PrePleat 62RM11 can provide an initial

efficiency of MERV 11, (60-65%) at a resistance of

.30" wg on the high capacity model. This equals

the same resistance level of our Pre-Pleat 40 62R

Merv 8 Pleat.

No competitor in the marketplace can match these

performance levels which are substantiated with

independent testing. Flanders is the first in the

marketplace with this new proprietary product.

General

This pleated air filter is designed for applications

where a UL Class 1 fire rated filter is required and

metal frame filters are unsuitable because of dis-

posal problems. The Pre Pleat Class 1 pleated air

filter has been tested by Underwriters Laboratories,

Incorporated and found to meet the stringent per-

formance characteristics of a Class 1 air filter for

flammability, as outlined in Standard 900. Class 1

air filter units are described as "Those that, when

clean, do not contribute fuel when attacked by

flame and emit only negligible amounts of smoke.”

Construction

The filter consists of a nominal 50% dust spot effi-

ciency micro-fine fiberglass filtration media that has

been bonded to a corrosion-resistant expanded

metal backing, and then pleated into either stan-

dard or high capacity packs. Each pack is encased

and sealed within a die-cut frame which is manu-

factured of special mineral-filled board to resist

flammability.

Pre Pleat Class 1 pleated air filters are offered in

two inch depth in all of the most popular face sizes.

E35

Pleated Panel Filters

Models E35-xxxxx

General

Flanders E35 extended surface pleated filters are

designed to operate in most installations. Available

in 1”, 2”, and 4” nominal thickness, these filters

have an average atmospheric dust spot efficiency

range of 25-30% per ASHRAE Standard 52.1 test

methods. E35 filters offer greater efficiency and

service life than disposable filters, pad and frame

systems, or metal washable filters. The overall

design of this product makes E35 filters the accept-

ed choice in applications requiring high perform-

ance and extended service.

These filters are suitable for variable air volume

systems. Operating face velocity ranges are from 0

to 500 fpm for 1” and 2” filters, and from 0 to 625

fpm for 4” filters. Each filter contains 11 pleats per

lineal foot. E35 filters are UL 900 Class 2 listed.

Versatility

Most heating, air conditioning, or ventilating sys-

tems can be upgraded with the use of E35 filters in

place of existing flat panel types. The inherent

strength of the filter allows for easy changeout as it

will not collapse, warp, or bend in normal service.

E35 filters are available in a wide range of sizes

and will fit most commercial and industrial installa-

tions with little or no system modification.

Fasteners are available to adapt the E35 filter to

existing filter banks.

Installation Considerations

E35 pleated filters are suitable as primary filters

and can be installed in Type 9 Holding Frames, K-

Track Framing Modules, Surepleat Side Access

Housings and similar existing hardware. They may

be used as prefilters for Flanders Precision Pak,

PrecisionCell and Rigid-Air filters in these framing

systems and in Sureseal Side Access Housings.

Construction

E35 filter frames are constructed from moisture

resistant chipboard. Perforated steel support grilles

on the upstream and downstream sides provide

extra rigidity and strength. The entire unit is sealed

to insure a positive media-to-frame bond, eliminat-

ing the possibility of air bypass. The filter media is

a high loft reinforced non-woven cotton/synthetic

blend. It is continuously laminated to an expanded

metal grid on the air leaving side to provide pleat

stability throughout the life of the filter and to pre-

vent media flutter while in operation. The E35 V

wedge pleat allows for total media usage and pro-

vides maximum airflow and dust holding capacity.

Important Features

•V-wedge pleats minimize end losses

and reduce pressure drop.

•Expanded metal grid prevents media flutter

while in operation.

•Perforated steel support grilles strengthen

the frame.

•Filter media pack is sealed to eliminate air

bypass.

•Average ASHRAE efficiency is 25-30%.

General

Superflow-V extended surface area low pressure

drop minipleat filters are designed for use in most

commercial and industrial HVAC systems where

medium to high efficiency filtration is required.

Superflow-V filters are available in average efficien-

cy ranges: 65%, 85%, 95% and 98% per ASHRAE

Standard 52.1 test methods and 95% DOP. They

may be operated at face velocities from 0 to 750

fpm. Superflow-V filters are UL 900 Class 2 listed.

Construction

Superflow-V filters are constructed of multiple mini-

pleat panels bonded to flame-retardant plastic pan-

els on top and bottom to make an unusually strong

assembly that is both corrosion and moisture resist-

ant. Aerodynamic extruded vertical supports mini-

mize air entry turbulence. Superflow-V filters are

totally rigid making them ideal for variable air vol-

ume (VAV) systems, as well as applications down-

stream of supply fans.

Lowest Pressure Drop

Superflow-V minipleat filters have an exceptionally

low clean pressure drop unmatched by most any fil-

ter of the same efficiency. This affords low fan ener-

gy costs during much of the life of the filter system.

In addition, they are the filters of choice for pack-

aged air conditioning systems that do not have the

fan capacity of larger central systems.

Longer Service Life

The ratio of media area to nominal face area of

Superflow-V filters is an extremely high 48:1, result-

ing in a much longer service life than most any filter

of comparable efficiency and depth. Longer service

life means material and labor cost savings and less

disruption of systems caused by filter change-out

shutdowns. High dust holding capacity is a key ben-

efit of a filter with increased media area.

Physical Data

Media: Moisture-resistant microfine fiberglass

Filter Pack: Minipleat panels

Media Support: Adhesive

Top and Bottom Panels: Flame-retardant plastic

Vertical Supports: Aerodynamic extruded vertical sup-

ports

Operating limits: 160 °F and 100% RH continuous duty

Actual Header Size: Nominal size less 5/8” (e.g. a nom-

inal 24” x 24” filter is actually 23-3/8” x 23-3/8”)

Actual Depth: 11-1/2”

Important Features

• Lowest clean pressure drop for energy savings

and applicability to small fan systems

• Longer service life because of a very high ratio of

media to nominal face area

• Aerodynamic vertical supports minimize air entry

turbulence

• Minipleat panels provide rigidity for VAV systems

and resistance to turbulent air flow

• May be operated from 0 to 750 fpm face velocity

in either air flow direction

• Moisture resistant for humid air applications

in two media types: lofted fiberglass and micro-fine

synthetic with average efficiency ranges of 50-55%,

60-65%, 80-85% and 90-95% per ASHRAE

Standard 52.1 test methods.

These filters are especially suitable for variable air

volume systems. Operating face velocity ranges

are from 0 to 375 fpm for 6” deep filters, and from 0

to 675 fpm for 12” deep filters. Two frame styles are

available: a single header model and a box type

without header. Rigid-Air filters are UL 900 Class 2

listed. Optional Class 1 listed are available with

metal inserts and fiberglass media.

Installation Considerations

Rigid-Air filters may be installed in Type 9 Holding

Frames, K-Trac Filter Framing Modules, Sureseal

Side Access Housings or in similar existing hard-

ware. Type 9 Holding Frames are riveted together

to form a bank and may be installed for upstream or

downstream service. K-Track Filter Framing

Modules are especially suitable for medium to large

built-up filter banks. Smaller systems and systems

with minimum upstream access space are best

served using Sureseal Side Access Housings.

The headered version should be selected for use

with the hardware listed above. If the filter is to be

installed so that it protrudes upstream of the Type 9

Holding Frame, the box style filter is required.

Rigid-Air Filter with Header and Plastic Pleat Separators

Flanders - Foremost in Air Filtration

Corporate Headquarters, St. Petersburg, FL

the filter and hvac store

Application Guidelines

Rigid-Air filters may be used wherever job require-

ments and available space will accommodate 6” or

12” deep filters.

Rigid-Air filters should be selected using 24” x 24”

and 24” x 12” face sizes. This allows for 12” incre-

ments in height and width of the filter bank and

insures that replacement cartridges will be readily

available.

Rigid-Air filters should be installed with pleats ver-

tical wherever possible. It is permissible to install

24” x 12” face size cartridges with pleats horizontal

if necessary to meet the size requirements of the

filter bank.

VAV Systems

Filter banks should be sized so that the maximum

rated flow at design conditions falls within the pub-

lished recommended velocities. Rigid-Air filters

may be applied at any capacity between zero flow

and cataloged capacities.

Hospital Applications

Rigid-Air filters may be used on the downstream

side of the supply fan in hospitals if they are far

enough from the fan so that the high fan discharge

velocity will not affect them. Rigid-Air rigid filters

can withstand adverse air flow conditions better

than bag filters and are the preferred selection for

these applications.

Gasketed Headers

Rigid-Air headered filters installed in Flanders K-

Trac Filter Framing Modules or Sureseal Side

Access Housings require gaskets on opposite

header sides to prevent air bypass.

To specify headered version Rigid-Air filters with

gasketed headers, add suffix “S” or “H” to the

model number. Example:

Model Number - S: Gaskets are on the sides paral-

lel to the pleats.

Model Number - H: Gaskets are on the sides per-

pendicular to the pleats.

1.0 General

1.1 Medium and high efficiency self-supporting filters

shall be Rigid-Air lofted fiberglass or micro-fine

synthetic media rigid filters as manufactured by

Flanders.

1.2 Filter sizes, efficiencies and capacities shall be

as scheduled on the drawings.

2.0 Filter Construction

2.1 Filters shall be constructed of lofted micro-fine

fiberglass or micro-fine synthetic media laminat-

ed to a non-woven backing, bonded to an

expanded metal wire grid and pleated to form the

filter pack

2.2 The filter pack shall be strengthened on the air

entering and air exiting sides with horizontal and

diagonal metal support members.

2.3 The enclosing frame shall be assembled in a

rigid manner and shall incorporate a header on

the air entering side if required by the applica-

tion.

2.4 The filter pack shall be sealed into a 24 ga.

corrosion-resistant steel casing with metal or

plastic pleat separators on the upstream and

downstream sides to maintain pleat configura-

tion.

3.0 Performance

3.1 Initial and final resistances shall not exceed the

scheduled values.

3.2 Media area must equal or exceed that of the

specified filter.

3.3 The average efficiency shall be as determined by

the ASHRAE Standard 52.1 test methods.

3.4 The manufacturer shall guarantee performance

as stated in its literature within tolerances as out-

lined is Section 7.4 of ARI Standard 850.

General

PrecisionCell extended media separator type rigid

filters are designed for use in most commercial or

industrial HVAC systems where medium to high effi-

ciency filtration is required. PrecisionCell filters are

available in average efficiency ranges of 60-65%,

80-85% and 90-95% per ASHRAE Standard 52.1

test methods and are available in standard and high

capacity versions.

These filters are suitable for variable air volume sys-

tems. Operating face velocity ranges are from 0 to

625 FPM for 12” deep filters. Three styles are avail-

able: box, single and double header. PrecisionCell

filters are UL 900 Class 1 listed.

Installation Considerations

PrecisionCell rigid filters may be installed in

Flanders Type 9 Holding Frames, K-Trac Filter

Framing Modules, Sureseal Side Access Housings,

or in similar existing hardware.

Type 9 Holding Frames are riveted together to form

a bank and may be installed for upstream or down-

stream service. K-Trac Filter Framing Modules are

especially suitable for medium to large built-up filter

banks. Smaller systems and systems with minimum

upstream access space are best served using

Sureseal Side Access Housings.

The single header version should be selected for

use with hardware framing systems and side access

housings. If the filter is installed so that it protrudes

upstream of the Type 9 Holding Frame, the double

header filter is required.

PrecisionCell Single Header filters are rec-

ommended for through-the-frame applica-

tions. Install by loading the filters through the

Type 9 frame until the header comes into

contact with the gasket on the frame. Secure

in place with Model P fasteners.

PrecisionCell Single Header filters are ideally suit-

ed for upstream or downstream installation in K-

Trac Filter Modules. Insert the horizontal sides of

the header in the gasketed 1” secondary track of

the framing system.

PrecisionCell Single Header filters are designed for

use in Sureseal Side Access Filter Housings. The

Sureseal unit provides space for prefilters to pro-

long the life of the filters. Install by sliding the head-

er of the filter into the gasketed 1” secondary filter

track.

Flanders - Foremost in Air Filtration

Corporate Headquarters, St. Petersburg, FL

the filter and hvac store

Application Guidelines

PrecisionCell filters may be used wherever job

requirements dictate totally rigid filters and available

space will allow only minimal inline depth.

PrecisionCell filters should be selected using 24” x

24” and 24” x 12” face sizes. This allows for 12”

increments in height and width of the filter bank and

insures that replacement cartridges will be readily

available.

PrecisionCell filters should be installed with separa-

tors vertical where ever possible. It is permissible to

install 24” x 12” face size cartridges with separators

horizontal if necessary to meet the size require-

ments of the filter bank.

Prefilters

We recommend that Prepleat 40 pleated panel fil-

ters or Precision Pak bag filters be used as prefilters

for PrecisionCell installations. Where there must be

long intervals between filter changes, we recom-

mend using 65% ASHRAE rated PrecisionPak as

prefilters. Refer to individual bulletins for perform-

ance data on these prefilters.

VAV Systems

Filter banks should be sized so that the maximum

rated flow at design conditions falls within the pub-

lished recommended velocities. PrecisionCell filters

may be applied at any capacity between zero flow

and cataloged capacities.

Hospital Applications

PrecisionCell filters are the preferred selection for

hospital systems where code or good practice

require that the filters be downstream of coils.

Gasketed Headers

PrecisionCell headered filters installed in Flanders

K-Trac Filter Framing Modules or Sureseal Side

Access Housings require gaskets on opposite head-

er sides to prevent air bypass.

To specify filters with gasketed headers, add suffix

“S” to “H” to the model number as follows:

Model Number - S: Gaskets are on the sides paral-

lel to the separators.

Model Number - H: Gaskets are on the sides per-

pendicular to the separators.

Gas Turbine Rigid Filters

ASHRAE 65%z: PGT65xxxxxxxH

ASHRAE 95%: PGT95xxxxxxxH

General

The PrecisionCell GT features heavy-duty con-

struction to meet the rigorous demands of gas tur-

bine rotary machinery air filtration applications.

They may also be utilized where extreme velocity or

turbulence have rendered other products to be inef-

fective. PrecisionCell GT filters are available in

ASHRAE efficiencies of 60-65% and 90-95% in

either single or double header versions.

Features

The PrecisionCell GT offers a high dust holding

capacity for increased service life, eliminating cost-

ly downtime and maintenance associated with filter

change out. The media is manufactured of a wet-

laid, moisture resistant, dual layer micro-fine fiber-

glass for high tensile strength and long service life.

The heavy gauge hemmed-edge corrugated alu-

minum separators offer increased pack rigidity with

optimal pleat spacing.

The heavy duty corrosion-resistant steel frame and

expanded metal faceguards on both the air entering

and air leaving sides protect the media pack.

Retainer straps on both sides prevent filter collapse

and maintain rigidity in high-pressure drop situa-

tions and blow back from turbine surges.

General

PrecisionCell II extended surface minipleat rigid fil-

ters are a nominal four inches deep. They are

designed for use in most commercial and industrial

HVAC systems where medium to high efficiency fil-

tration is required. They are available in average

efficiency ranges of 60-65%, 80-85% and 90-95%

per ASHRAE Standard 52.1 atmospheric dust spot

test methods.

PrecisionCell II filters are especially suitable for

variable air volume systems and are designed to

operate at face velocities up to 625 fpm. Two styles

are available: standard box style and an optional

headered (top and bottom) version that are manu-

factured with a header for use with existing side

access housings (see Optional Model).

PrecisionCell II filters are UL 900 Class 2 listed.

Optional Model

Optional headered version PrecisionCell II filters

are the same size and have the same functional

design as the standard model. The filter is built with

a metal-reinforced header on the top and bottom of

the filter near the air entering side. The header

allows the filter to fit over the standing flanges of the

primary filter channel in existing side access hous-

ings. Headered PrecisionCell II filters are furnished

with a 1/2” wide polyfoam gasket on their vertical

sides to provide a filter-to-filter seal.

In-Line Space-Saving Design

PrecisionCell II filters dramatically reduce in-line

space requirements when compared to 12” to 36”

deep filters. Their nominal 4” depth makes a con-

venient “fit” for most installations. High efficiency fil-

tration, that is often required for acceptable Indoor

Air Quality, may now be selected by the design

engineer without having to compromise space.

Installation Considerations

PrecisionCell II filters may be installed in Flanders

Type 9 Holding Frames and Surepleat Side Access

Housings or similar existing hardware. Type 9

Holding Frames are riveted together to form a bank

and may be installed for upstream or downstream

service. Smaller systems and systems with mini-

mum upstream access space are best served using

Surepleat Side Access Housings.

Physical Data

Frame: Double-wall, moisture-resistant beverage board

Media: Water-laid microfine fiberglass with a

water-repellent binder

Media Support: Adhesive-bead pleat separators

Face Grid: Horizontal and diagonal supports bonded to

the media pack

Construction

In the Flanders tradition of state-of-the-art technology, PrecisionCell II filters are built with a minipleat media

pack to achieve a rugged, compact lightweight, high efficiency filter.

Surepleat Side Access Housings

Use a Surepleat Side Access Housing as a con-

venient and space-saving method of installing

PrecisionCell II filters. SP2/4 housings have two

gasketed extruded aluminum tracks to accept 2”

pleated prefilters and 4” PrecisionCell II final fil-

ters.

The adjacent photo shows a Surepleat Side

Access Housing with 2” Prepleat 40 pleated pre-

filters and PrecisionCell II final filters.

Flanders - Foremost in Air Filtration

Corporate Headquarters, St. Petersburg, FL

the filter and hvac store

Prefilters

Prefilters are always a wise choice for the protec-

tion of minipleat filters no matter what the efficiency

or brand. The closely-spaced pleats are subject to

face-loading (bridging) by lint and coarse particles,

thus reducing their usual long life. A minimum 25-

30% ASHRAE efficiency pleated panel filter such

as the Flanders Prepleat 40 is recommended.

Save In-Line Space

Compare the airway lengths of 22” PrecisionPak

bag filters and 12” Rigid-Air filter to a 4”

PrecisionCell filter when they are installed with 2”

prefilters.

VAV Systems

Filter banks should be sized so that the face veloc-

ity at maximum design conditions is 625 fpm or

less. PrecisionCell II filters may be applied at any

capacity between 0 and 625 fpm. Operating a filter

bank at reduced flow will greatly increase expected

filter life.

Save Storage Space and Shipping Costs

Using the 24” x 24” size as an example, a carton of

four PrecisionCell II 4” filters has a volume of 5.3

cubic feet and a weight of 26 lbs. Compare this to

four 12” deep rigid separator-type filters packed in

four cartons with a total volume of 16 cubic feet and

total weight of 80 lbs.

Application Guidelines

PrecisionCell II filters should be selected for new

installations with 24” H x 24” W and 24” H x 12” W

face sizes. These are the most widely used and

stocked sizes. This allows for 12” increments in

height and width of the filter bank and insures that

replacement cartridges will be readily available.

PrecisionCell II filters should be installed with the

pleats vertical wherever possible. It is permissible

to install 24” H x 12” W face size filters with pleats

horizontal if necessary to meet the size require-

ments of the filter bank.

HEPA Prefilters

PrecisionCell II filters are ideal as prefilters for

Alpha Cell HEPA filters. Their light weight and 4”

depth make them an excellent choice for installa-

tion in the optional Prefilter Frame Assembly for the

Alpha Cell HEPA Filter Holding Frame or in

Surelock Side Access HEPA Housings.

Specify the Surelock housing with an optional 4”

wide prefilter track for the PrecisionCell II filters, in

lieu of the 2” wide prefilter track for pleated panel fil-

ters. We recommend the selection of 80-85%

PrecisionCell II filters as HEPA prefilters.

ASHRAE 30%: EA-30xx ASHRAE 55%: EA-55xx

ASHRAE 85%: EA-85xx ASHRAE 95%: EA-95xx

General

EA Series Replacement Air Filters are pre-formed,

extended surface deep-pleated cartridges for use

with existing hardware in commercial and industrial

HVAC systems. EA Series filters are available in

average efficiency ranges of 25-30%, 50-55%, 80-

85% and 90-95% when tested according to

ASHRAE Standard 52.1 methods. EA Series filters

are UL 900 listed Class 2.

Construction

EA filter media is a non-woven cotton and synthet-

ic blend (25% efficient) or moisture-resistant micro-

fine lofted glass fiber (55%,85%or 95% efficient).

The media is reinforced with a non-woven remay

backing and formed into a “pack” which is then hot-

melt bonded top and bottom to 1/16” thick stiff mois-

ture-resistant fiberboard panels. Alignment of the

pleats in the media pack is carefully controlled dur-

ing the bonding operation to facilitate insertion of

the cartridge into the wire media retainer during

installation. The completed filter is folded before

being boxed to minimize shipping and storage vol-

ume.

Application

EA Series cartridge filters are designed to be used

only in existing hardware as pictured below. This

hardware consists of metal holding frames, sealer

frames and wire basket-type retainers that may be

used in either front or rear-loading built-up filter

banks or side access housings.

EA Cartridge Disposable Replacement Air Filters

are fully interchangeable with other manufacturers’

cartridge filters and hardware. Units of one effi-

ciency may be replaced in the same system hard-

ware with similar size and depth units of another

efficiency. When upgrading efficiencies, be sure to

check the capability of the fan to overcome the

increased pressure drop.

Guide Specifications

Application Guidelines

Precision Pak filters should be selected using 24” x

12” face sizes. This allows for 12” increments in

height and width of the filter bank and insures that

replacement filters will be readily available.

Precision Pak filters should be installed with pockets

vertical wherever possible. It is acceptable to install

24” x 12” face size filters with pockets horizontal if

necessary to meet the size requirements of the filter

banks.

Gasketed Headers

Precision Pak filters installed in Flanders K-Trac

Filter Framing Modules or Sureseal Side Access

Housings require polyfoamgaskets on opposite

header sides to prevent air bypass. To specify

Precision Pak filters with gasketed headers, add

suffix ”S” or “H” to the model number.

Prefilters

Properly selected bag filters without prefilters will

generally require changeout annually in typical

HVAC applications. Because of the frequent main-

tenance expense and increase in fan kW input using

prefilters, they are often recommended with 85%

and 95% efficient Precision Pak final filters.

However, the energy cost to operate a prefilter sel-

dom warrants their use with 55% or 65% filters.

1.0 General

1.1 Medium and high efficiency self-supporting filters

shall be Precision Pak extended surface type as

manufactured by Flanders.

1.2 Filter sizes, efficiencies and capacities shall be

as scheduled on the drawings.

2.0 Filter Construction

2.1 Filters shall be constructed of lofted fiberglass or

micro-fine synthetic media encased in a thin non-

woven polyester backer mat.

2.2 Open area on the filter face for air passage shall

be not less than 90%.

2.3 Flexible internal support stitching shall maintain

individual pockets in a controlled form under all

rated air flow conditions. Stitchings shall be

sealed with thermoplastic sealant. Edges shall

be finished with overlock stitch to prevent air

unravelling.

2.4 Pockets shall be 100% stake-through crimped to

prevent media pull-out

2.5 Pockets shall be bonded to corrosion-resistant

steel casings and assembled into a corrosion-

resistant steel header.

2.6 Filters shall be UL 900 Class 2 or Class 1 listed.

3.0 Performance

3.1 Initial and final resistances shall not exceed the

scheduled values.

3.2 Media area must equal or exceed that of the spec-

ified filter.

3.3 The average efficiency shall be as determined by

the ASHRAE Standard 52.1 test methods.

3.4 The manufacturer shall guarantee performance

as stated in its literature within tolerances as out-

lined is Section 7.4 of ARI Standard 850.

General

Precision Pak XDH high dust holding capacity

extended surface bag filters are designed for use in

most commercial or industrial HVAC systems

where medium to high efficiency filtration is

required. Precision Pak XDH filters are available in

micro-fine polyolefin synthetic media with average

efficiency ranges of 75%, 85% and 95% per

ASHRAE Standard 52.1 test methods. Operating

face velocities up to 625 fpm are available for all

models. Precision Pak XDH filters in depths of 12”

and 22” are suited for variable air volume systems.

Filters with greater depth are not recommended.

Precision Pak XDH filters are UL 900 Class 2 list-

ed.

Kimberly-Clark Media

Precision Pak XDH bag filters use Kimberly-Clark

brand polyolefin synthetic media. The media is

thermally bonded without binders and consists of

non-woven continuous hydrophobic (water repel-

lent) fibers that resist water and most chemicals. In

addition, the media is gradient density, dual stage

and electrostatically enhanced for extra high dust

holding (XDH) capability. Further, the media is

non-shedding and performs exceptionally well in

high velocity and turbulent applications.

Extra High Dust Holding

Atypical XDH bag filter was tested for ASHRAE

synthetic dust holding capacity against similar fil-

ters with fiberglass and meltblown synthetic media.

Results showed that the XDH filter held approxi-

mately 110% more dust by weight than the others

when run to the same final resistance. This char-

acteristic makes it an excellent choice for very

dusty areas and for those systems where long

service life and reduced maintenance are key con-

cerns.

to install 24” x 12” face size filters with pockets hor-

izontal if necessary to meet the size requirements

of the filter banks.

VAV Systems

VAV systems can be designed using the full range

depth of Precision Pak XDH filters. Filter banks

should be sized so that the maximum rated flow at

design conditions falls within the published recom-

mended velocities. Precision Pak XDH filters in all

standard depths can be applied at any capacity

between zero flow and catalog-rated capacities.

Gasketed Headers

Precision Pak XDH filters installed in Flanders K-

Trac Filter Framing Modules or Sureseal Side

Access Housings require polyfoam gaskets on

opposite header sides to prevent air bypass.

To specify Precision Pak XDH filters with gasketed

headers, add suffix “S” or “H” to the model number.

Use “S” gaskets on the sides parallel to the pockets

and “H” for gaskets on sides perpendicular to the

pockets.

Prefilters

Properly selected bag filters without prefilters will

generally require changeout annually in typical

HVAC applications. Because of the frequent main-

tenance expense and increase in fan kW input

using prefilters, they are seldom recommended on

lower efficiency final filters. However, prefilters are

often used on 85% and 95% efficiency applications.

Guide Specifications

General

Flanders models MS and MSG Moisture

Separators are designed for use in air handling sys-

tems requiring collection of water droplets or oil

mist. Water droplets in outside air are usually fog.

In supply air, water droplets may occur as carry

over from cooling coils and evaporative media or

unevaporated moisture downstream of humidifiers.

Oil mist in return air is most often found in produc-

tion machine shops.

Application

The optimum face velocity for MS and MSG

Moisture Separators is 500 fpm, and at this point

they are 98% efficient on 20 micrometer liquid

droplets. Performance is relatively unchanged in

the recommended range of 450 fpm to 550 fpm.

Above 550 fpm captured liquid may be re-entrained

in the airstream.

The system designer must recognize that moisture

separators will also act as low efficiency particulate

prefilters and that the separator bank pressure drop

will increase over time. System static pressure cal-

culations for fan selection should include an

allowance of at least 0.50 inch w.g. final static pres-

sure for dirty wet moisture separators.

Models MS and MSG Moisture Separators are

meant to be installed with their pleats vertical so

that collected liquid will drain easily to the bottom of

the frame and out through five 3/8” diameter holes.

The top of the frame has an arrow to guide the

installer as to the proper air flow direction and posi-

tion for proper drainage

Installation Considerations

In a mixed air (outside air/return air) system, place

the Moisture Separators in the outside air duct if

possible. Otherwise, place them as the first filtra-

tion stage ahead of the particulate filters.

Moisture Separators may be installed in built-up

banks using Flanders Type 9 Holding Frames or in

Flanders Side Access Housings specially equipped

with drain tubes. When built-up banks are used,

field-fabricated water drain pans should be installed

between each horizontal row of frames.

For banks four or five separators wide, locate 3/4”

I.D. downspouts at each end. For banks six sepa-

rators wide or wider, locate downspouts at each

end and proportionately along the width of the

bank, one for every six separators or a fraction

thereof. Example: a six separator wide bank would

have downspouts at both ends and one in the mid-

dle; an eight separator wide bank would have

downspouts at both ends and two more proportion-

ately spaced along the width of the bank. If not indi-

vidually trapped, the downspouts should be mani-

folded to a 1” I.D. or larger collector with a trap of a

depth exceeding the negative pressure expected in

the plenum where the separator bank is located.

Sureseal two-stage Side Access Housings may be

special-ordered with the 2” tracks fitted with drain

tubes to hold both Moisture Separators and partic-

ulate final filters. If the 2” tracks are to be used for

2” prefilters, a Surepleat single-stage Side Access

Housing with drain tube should be selected and

located upstream of the particulate filter housing.

General

Flanders Model KKM is a heavy duty, washable,

aluminum media, all metal filter. KKM is suitable for

all residential and commercial applications.

The KKM offers large filtering area, high dust hold-

ing capacity, uniform loading and low resistance to

air flow. It is recommended that the filter media be

coated with dust adhesive for optimum perform-

ance.

Construction

The KKM filter has a rugged galvanized steel frame

that encloses the bonded expanded aluminum

mesh media. The corners are mitered and the

frame is secured with pop rivet(s). The KKM has

drain holes in three corners.

The bonded aluminum media is slit and expanded

to several different size openings. This design

allows contaminants to be trapped throughout the

entire filter depth and not just at the surface. The

media is retained within the frame by expanded gal-

vanized steel.

An all-aluminum version of the KKM is also offered,

which has an aluminum frame and is constructed

with expanded aluminum retainers.

The standard offering of KKM filters includes six of

the most popular face sizes in 1” and 2” depths.

Special face sizes and 1/2” depth filters are also

available. For ease of installation, all filters are

undercut slightly on length, width and depth.

Filter Coating and Cleaning

The KKM performs best as an impingement type fil-

ter. Optimum performance requires use of a dust

adhesive on the media. Flanders offers Filter

Boost.

Wash with a mild detergent and rinse to remove

collected dust.

General

Flanders Alpha 95 Filters are designed for use in

HVAC applications requiring cleaner air than is pos-

sible with ASHRAE - rated filters, but where HEPA

- filtered air is not required. The filters are rated at

95% efficiency on 0.30 micrometer particles by the

DOP test method. The Alpha 95 filter is approxi-

mately 99% efficient by the ASHRAE 52.1 dust spot

test methods. However, it is not rated by these

methods because the standard applies to filters no

greater than 98% efficient.

Alpha 95 Filters are 97% efficient on nebulized

staphylococcus aerosols and are used to remove

biological contaminants. Alpha 95 Filters are identi-

cal in design and construction to the Alpha Cell

HEPA Filters except that the media is 95% efficient

on 0.30 micrometer particles.

Installation Considerations

Alpha 95 Filters should be installed in Flanders leak

tight Alpha HEPA frames or Surelock Side Access

HEPA Housings on the positive-pressure side of the

system fan to prevent air bypass. Sureaire diffuser

sections, air mixing baffles or long transitions

should be used if the bank is close to the fan.

Installation of Flanders 80-85% ASHRAE efficien-

cy prefilters upstream of the fan is recommended to

ensure economical Alpha 95 Filter life.

Standard Alpha 95 Filters have 1.7 times the cfm

capacity of standard Alpha Cell 99.97% DOP HEPA

Filters at the same clean pressure drop. They are

normally rated at 500 fpm so that filter banks with

95% DOP filters can be sized the same as

ASHRAE-rated filter banks.

Typical applications for Alpha 95 Filters include:

• Hospitals

• Biomedical

• Pharmaceutical

• Biotechnology

• Genetic Research

• Universities

• Laboratories

• Food Processing

• Photo Processing

• Semiconductor Fabrication

• Industrial Processing Systems Product

Important Features

• Minimum efficiency is 95% on 0.30 micrometer

particles.

• Manufactured in a variety of wood and metal

frame types.

• Available with a media pack with aluminum sep-

arators or with a separatorless pack.

• Available in a variety of sizes with either a gas-

ket seal or gel seal.

Construction

Flanders manufactures both conventional Separator

Style and Pureform Separatorless 95 DOP Filters. To

make a Separator Style filter, the media is folded over

corrugated aluminum separators with hemmed edges

to separate the pleats in the filter pack. Flanders

manufactures its own filter media, enabling it to

develop a unique manufacturing process for the pro-

duction of Pureform Separatorless 95 DOP Filters. In

one manufacturing operation, Flanders produces a

self-supporting and self-separating Pureform Media

Pack.

The Pureform Filter offers many advantages over con-

ventional Separator Style 95% DOP Filters:

• Increased usable media area affords longer service

life and higher dust holding capacity

• Maximum utilization of the media

• Can handle some harsh environments which may

attack aluminum separators

• Media pack can be incinerated

• Media is 28 mils, significantly thicker than conven-

tional media used in Separator Style 95 DOP Filters

(15 mil)

• 11” deep PUREFORM Pack has 261 sq. ft. of media

as compared to 175 sq. ft. for a conventional

Separator Style filter.

• Ideal for heavy loading applications such as oil mist.

General

Flanders offers a complete line of Alpha Cell HEPA

Filters in two efficiencies to meet the needs of criti-

cal applications where HEPA filtration is required.

Individual testing, rigid quality control and modern

assembly methods are used to ensure confor-

mance to specifications. Alpha Cell HEPA and

ULPA Filters are either UL 900 Class 1 or Class 2

listed.

Testing

Flanders individually tests and certifies each Alpha

Cell HEPA Filter to meet the customer’s require-

ments for resistance and efficiency (penetration) at

the filters nominal rated capacity. This information

appears on a test label affixed to the filter. When

used with correctly selected and installed mounting

frames or housings, Flanders Alpha Cell HEPA

Filters will easily pass an in-place validation test to

determine the overall system efficiency.

HEPA FILTERS

Each Alpha Cell HEPA Filter has a minimum effi-

ciency of 99.97% on 0.30 micrometer size particles

when tested at rated capacity on a Q-107

Penetrometer. Filters rated for 1000 cfm or less are

challenged with an approved nearly monodis-

persed oil aerosol of 0.30 micrometer size. Filters

rated for flows greater than 1000 cfm are tested

using a polydispersed oil aerosol. By measuring the

upstream and downstream concentration of these

particles with a light scattering photometer, the pen-

etration can be determined and the efficiency can

be calculated.

Scan Tested HEPA Filters

Each Scan Tested Alpha Cell HEPA filter has a min-

imum efficiency of 99.99% on 0.30 micrometer par-

ticles. Scan testing is in accordance with Section

6.2 of IEST-RP-CC034.1, HEPA and ULPA Filter

Leak Tests. In the scan test, the filter is challenged

with a high concentration of an approved oil aerosol

or PSL (Polystyrene Latex Spheres). The media

pack and pack-to-frame seal is scanned using a

photometer or particle counter to ensure that there

are no leaks greater than .01% of the upstream

concentration at 100 fpm face velocity.

Higher Efficiency ULPA Filters

Flanders can provide Pureform®and Separator

Style ULPA Filters with efficiencies up to 99.9995%

on 0.12 micrometer size particles. Please contact

the factory for more information.

High Capacity Design

The Alpha 2000 High Capacity HEPA filter is avail-

able in a nominal 12” depth configuration. It is

designed for optimum performance and low operat-

ing costs in both new and replacement systems.

With 40% more media area than the standard

capacity Alpha Cell filter, the Alpha 2000 saves

space, energy, and material and labor costs.

Save Space

Alpha 2000 HEPA filters operate at 500 fpm (2000

cfm for a 24” x 24” size) at 1.45 inch w.g. clean

pressure drop versus conventional Alpha Cell filters

that operate at 250 fpm and 1.0 inch w.g. clean

pressure drop.

Construction

Apopular construction option consists of 16 ga.

galvaneal frames and moisture-resistant microfine

wet-laid fiberglass media folded over hemmed-

edge low amplitude corrugated aluminum separa-

tors. The filter pack is bonded to the frame by a fire-

retardant urethane elastomer to provide a rigid

leak-free assembly.

Save Energy

Alpha 2000 filters in a conventional HEPA filter

bank impose a lighter load on the fan when operat-

ed at conventional 250 fpm velocities during the life

of the filters. The Alpha 2000 99.97% and 99.99%

high capacity 24” X 24” X 12” filter has a clean pres-

sure drop of 1.1 inch w.g. at 1500 cfm, compared to

standard Alpha Cell filters with a clean pressure

drop of 1.50 inch w.g. at the same air flow.

Save Replacement Material and Labor

Costs

Savings are significant with high capacity Alpha

2000 filters. They operate at lower velocities and

provide life cycles up to three times the life of stan-

dard capacity filters. Savings are achieved in

replacement materials and labor costs as a result of

fewer filters.

Holding Frames and Housings

Alpha Frames are designed for Alpha 2000 filters in built-up filter banks. Each filter is secured in the frame

with four bolt-type fasteners that either compress the gasket or press the knife edge into the gel in the filter

channel to maintain a leak-tight seal.

Surelock HEPA Filter Housings are recommended for side-access applications. The filters are sealed in

place with either spring-loaded swing arm assemblies or a locking mechanism. The swing arm assemblies

or locking mechanism either compress the gasket or press the knife edge into the gel in the filter channel

to maintain a leak-tight seal.

General

Flanders manufactures metal-frame separator-style

HEPA filters for applications with high-temperature

requirements up to 1,000°F (540°C) for exhaust air

only and 500°F (260°C) for supply air. High-tem-

perature filters are available with either a gasket or

fluid seal. Filters with Blu-Jel®Fluid Seal have a

maximum service temperature of 390°F (199°C)

HEPA Filters

Each HEPA filter has a minimum efficiency of

99.97% on 0.30 micrometer size particles when

tested at rated capacity on a Q-107 Penetrometer.

Each filter is challenged with an approved nearly

monodispersed oil aerosol of 0.30 micrometer size

and by measuring the upstream and downstream

concentration of these particles with a light scatter-

ing photometer, the penetration can be determined

and the efficiency can be calculated.

Scan Tested HEPA Filters

Each Scan Tested HEPA filter has a minimum effi-

ciency of 99.99% on 0.30 micrometer particles.

Scan testing is in accordance with Section 6.2 of

IEST-RP-CC034.1, HEPA and ULPA Filters Leak

Tests. In the scan test, the filter is challenged with

a high concentration of an approved oil aerosol or

PSL (Polystyrene Latex Spheres). The media pack

and pack-to-frame seal is scanned using a pho-

tometer or particle counter to insure that there are

no leaks greater than .01% of the upstream con-

centration at 100 fpm face velocity. Scan testing is

only available for the 500°F model.

Sealant Types

Two types of sealants for high-temperature HEPA

filters are offered.

Silicone Sealant

This is a high temperature (RTV) silastic-sealant sil-

icone compound rated for continuous service up to

500°F(260°C). NOTE: This high-temperature

sealant is not UL 586 approved.

Glass Pack Sealant For Exhaust Air Only

The glass pack seal is rated for continuous service

up to 1,000°F(540°C) in exhaust air applications

only. It is a mat of submicron glass fibers that cre-

ates a seal when compressed between the filter

pack and filter frame. The glass packing is not an

adhesive seal but a mechanical seal that functions

much as the glass fiber medium of the filter itself.

NOTE: Due to the possibility that the glass pack

may shed glass fibers, the glass pack sealant

should be used for exhaust systems only.

General

Flanders Superflow 2K is a V-bed HEPA filter

(99.99% at 0.30 micrometer) specifically designed

for high airflow applications requiring HEPA effi-

ciency at an ultra low pressure drop. The Superflow

2K can be incorporated into systems with air veloc-

ities of 500 fpm and a pressure drop of 1.0 inch w.g.

Product Design

The Superflow 2K filters are manufactured with wet

laid microfine fiberglass media. The media is

formed into a minipleat utilizing a hot melt separa-

tor and arranged in a V-bed configuration. There

are 10 individual minipleat packs that are sealed on

all four sides to the frame with a two component

polyurethane.

The frame is constructed of 16 ga. galvaneal steel

and consists of vertical support struts of the same

material. Vertical supports are attached to the

frame body without the use of mechanical fasten-

ers. The vertical supports act as the sealing surface

of the mini pleat packs.

Features and Benefits

The product offers the following advantages over

conventional HEPA filters.

• Longer Life – Gasket seal Superflow 2K filters

have 290 sq. ft. of media compared to 140 sq. ft. for

traditional HEPA filters. The greater media area pro-

vides a longer time period between filter replace-

ments.

• Improved Efficiency – The significant quantity of

media translates into an extremely low media

velocity. Therefore a minimum overall efficiency of

99.99% at 0.30 µm is easily assured. Traditional

HEPA filters have an overall efficiency of 99.97% at

0.30 µm.

• Lower Operating Cost – The typical HEPA filter

pressure drop can range from 1.4 inch w.g. to 1.8

inch w.g. at the rated flow. The pressure drop of the

Superflow 2K is 1.0 inch w.g. at the rated flow.

Product Options

The Superflow 2K filters are available in aluminum

or stainless steel frames and with gasket seal or gel

seal design.

Gasket Seal

The filter gasket is 1/4” x 3/4” black neoprene

attached to the frame with an adhesive and the

gasket joints are dovetailed to ensure no penetra-

tion of particulate due to the gasket. The filter is

designed for installation into Flanders front load B-

1 holding frame, Surelock C Gasket Seal Housing

and Surelock-B Side Access Housing.

Gel Seal

The filter gasket is Flanders Blu Jel filled into a

channel around the perimeter of the frame. The gel

seal design provides the highest degree of sealing

integrity between the filter and holding device. The

filter is designed for installation into Flanders front

load A-4 holding frame or Surelock-C Jel Seal

Housings.

Flanders Pureflo Terminal HEPA/ULPA Filter

Modules are lightweight low profile ducted units.

The mini-pleat filter packs are designed to provide

unidirectional airflow from tee-bar ceilings. Pureflo

modules are available in two sizes: nominal 24” x

24” and 24” x 48” with either 10” or 12” diameter

inlet collars. They are available in two particle size

efficiencies: 99.99% on .0.30 µm and 99.9995% on

0.12 µm and in three filter pack depths: 53, 70 and

100 mm

Installation and Application

Considerations

Pureflo Terminal HEPA/ULPA Filter Modules are

recommended for use in ultraclean applications.

They are ideal for fabrication of microelectronics,

semiconductors, and medical devices; and in aero-

space, biotech and pharmaceutical production.

Selection of the PF70 or PF100 models will help

reduce operating costs because of their lower

resistance and longer service life.

Clips on the module’s top four corners are to be

used to secure seismic restraint wires. Polyfoam

gasket should be applied to the tee-bar surface on

which the module will rest.

The standard face velocity range of 70 to 110 fpm

is easily adjusted from the room side by a screw-

driver operated damper. Static pressure and chal-

lenge aerosol measurements can be taken from a

separate room side port. Standard construction

allows the modules to be operated at a pressure

drop of 2.0 inches w.g.

Construction

The heart of the Pureflo module is a state-of-the-

art minipleat filter pack sealed in an anodized

extruded aluminum casing forming the sides of the

module. The extruded aluminum center divider

holds ports for in-room damper adjustment and

measurement of the challenge aerosol. The one

piece hood/inlet collar is made of aluminum and the

inlet collar is dimpled to secure the flex duct retain-

ing strap. A 20 ga. expanded steel white powder-

coated face grille protects the media pack. Each

module is scan-tested after assembly to meet or

exceed IEST RP-1 requirements for a Type C or F

filter.

Options

Pureflo Modules are available with either nominal

10” or 12” diameter inlet collars. One inch thick

vinyl-backed fiberglass insulation on the top and

sides of the module is also available.

(Where * is efficiency designator of 493 for 99.99% efficient on .3 micron

particles and 591 is 99.9995% efficient on .12 micron particles.)

General

Pureflo-FPM Fan-Powered Terminal HEPA/ULPA

Filter Modules are lightweight unitized low profile

units consisting of a fan/motor assembly and a

minipleat HEPA/ULPA filter pack, designed to pro-

vide unidirectional vertical airflow from tee-bar ceil-

ings. The modules are available in two sizes: nom-

inal 24” x 24” and 24” x 48”; and in two types: a

standard replaceable unit and a room side replace-

able (RSR) unit. Module efficiencies are 99.99% on

0.3 micron particles or 99.9995% on 0.12 micron

particles.

Options

• Nominal 10” or 12” duct collars for conditioned air

• UL Class 1 dimple pleat HEPA filter

• 25-30% efficient pleated prefilter

• Power cord for 115V modules

• 220V 50/60 Hz fan motor

• 277V 60 Hz fan motor

• Integral dual polarity DC air ionizing bar

• Neoprene Gasketed RSR filter pack

• Power indicator light

Application and Installation Considerations

Pureflo-FPM modules are recommended for use in

clean- room applications for fabrication of micro-

electronics, semiconductors, and medical devices.

The filters in standard modules are table-top

replaceable with the entire unit removed from the

ceiling. The filters in room side replaceable (RSR)

modules have an integral extruded channel filled

with cleanroom quality sealing gel. The filters are

clamped into the fan plenum against a continuous

knife edge that is embedded into the gel for a

leakproof seal. Removal of the filter does not dis-

turb the enclosure. Neoprene gasketed filters are

available as an option. Modules include threaded

inserts with 1/4” eyebolts at each top corner for the

attachment of seismic restraint wires. Polyfoam

gasket material should be applied to the tee-bar

surfaces on which the modules rest.

Performance

Pureflo-FPM modules produce HEPA or ULPA fil-

tered air at a velocity of 90 fpm + 15 fpm six inches

below the filter face. When using the solid state

speed control, the sound level 30 inch from the fil-

ter face is approximately 53 dbA (nc45) at a 90 fpm

average face velocity and an ambient sound level

of 25 dbA.

Construction

HEPA filter: Separatorless minipleat with water-

resistant microfine fiberglass media 2.1” (53 mm)

on STD models, and 2.76” (70 mm) on RSR

models.

Improves IAQ through odor abatement

and better particulate air filtration

Many strong odors in living spaces come from

materials that are either strong acids or strong

bases. For example, sauerkraut smells up the

house because it is highly acidic. And the “ammo-

nia” smell of urine is highly alkaline...a strong base.

The Flanders PH Odor Control Pleat is specifically

designed to bring both types of odor

molecules...acid or base...into a more neutral, PH

balanced, odor free state.

The secret of this filter’s odor effectiveness is sodi-

um bicarbonate. It is basically an industrial version

of the baking soda you put in the fridge to remove

odors. The media fibers of the PH Odor Control

Pleat are coated with this material.

And it is sodium bicarbonate’s natural ability to neu-

tralize both acids and bases...balance their

PH...that makes the PH Odor Control filter effective

as a wide spectrum odor neutralizer.

Bonus...better particulate filtration

Fractional efficiency tests on the sodium bicarbon-

ate treated filter medium showed it to perform bet-

ter on particulates as well as on acid and alkaline

odors. Treatment caused no change in pressure

drop.

Examples of applications that might benefit from

such a filter include family residences, hotel rooms,

nursing facilities, athletic clubs and other areas with

odors that come from strong acids or strong bases.

Construction

Cotton and polyester pleat media is prepared by

immersion in a special sodium bicarbonate slurry,

then dried. Media is adhered to galvanized

expanded metal and deep pleated. Pleated pack is

encased and sealed within a moisture resistant

kraft board frame. This filter is offered in 1”, 2” and

4” depths in all of the most popular face sizes, plus

special sizes.

Sensory testing

Body Odor

Odor level testing was conducted in jars set up spe-

cially for headspace odor

testing. Sensory evalua-

tion was run 20 hours

after the jars had been

set up to allow for ade-

quate equilibration. 20

panelists participated in

headspace odor level

testing. The malodor in

the headspace was iso-

valeric acid vapor

(Synthetic Sweat Odor)

that had passed through the filter material.

Untreated filter media was tested vs filter media

treated with baking soda. The chart shows the

average odor levels reported by panelists. A 1 to 10

scale was used, where 1 is no malodor and 10 is

extreme malodor. The difference in scores was sta-

tistically significant at the 99% confidence level.

Strong Food Odor

Deodorization testing was run in sensory rooms. In

each room, a malodor source consisting of 100

grams of sauerkraut was placed behind a 20”x20”

box fan which recirculated the air. Attached to the

outlet of each fan was a

20”x20” filter. A filter

treated with baking soda

was attached to one and

an untreated filter

attached to the other.

The graph here illus-

trates results as rated by

20 panelists. Levels of

odor were rated on a 1 to

10 scale. Initially (after 1

hour), both rooms showed a high level of malodor.

As time passed, the room with the baking soda

treated filter generated lower odor scores. The 18

hour score is statistically significant at the 90% con-

fidence level.

Urine Odor

Cat urine was tested

using the same appara-

tus and method as the

sauerkraut test. The

odor source was a 6”x6”

carpet swatch that had

been sprayed with 0.70

grams of cat urine. The

chart at left shows the

perceived odor levels in

the rooms. The differ-

ences in score for hours

1 and 5 are statistically significant at the 90% con-

fidence level.

Media specification

The filter media shall be manufactured using fine

grain sodium bicarbonate (baking soda) at a rate of

2 grams per square foot of media. The baking soda

will be uniform through the thickness of the media.

Amajority of individual media fibers will be coated

with the fine-grained baking soda. The sodium

bicarbonate coating will be adhered to the fibers.

Proof of fiber coating and uniformity through the

media is to be given in the form of electron micro-

scopic photographs. The media will have a mini-

mum SO2 efficiency of 40% at one hour when test-

ed at the National Ambient Air Quality Standard

(NAAQS) at 1000 cfm.

Model C

Disposable Carbon

Gas Phase Odor Control Filters

50% Fill,models: C50-xxxxx 75% fill,models: C75-xxxxxx

General

The Model C Disposable Carbon air filter is an

easy-to-install partial-bypass carbon type air purifi-

er for light duty IAQ applications in home and com-

mercial recirculated air systems. The filter uses

premium grade granular virgin coconut shell carbon

to remove odors by the adsorption process rather

than masking them with air fresheners. Odors are

controlled by surface adsorption on the carbon,

which has over one million square feet of surface

area per square foot of filter face area. Typical

household applications are the removal of odors

from bathrooms, cooking, smoking and entertain-

ing. Commercial applications may include restau-

rants, schools, medical offices, beauty salons,

health clubs, and offices.

Construction

Alaminated cellulose honeycomb material forms

the base structure of the filter. The honeycomb pro-

vides for the exposure of a great amount of surface

area for full utilization of the carbon. Each individual

honeycomb cell is filled with granular activated car-

bon to either the 50% or 75% level. The 75% fill fil-

ter has a longer life than the 50% fill filter, but its air-

way pressure drop is greater.

The carbon is retained within the honeycomb cells

by a non-woven nylon mesh on both sides of the fil-

ter. The honeycomb is given additional strength by

a moisture-resistant die-cut beverage board frame

(standard sizes) or U-channel beverage board

(special sizes). Each order is individually sealed in

plastic to retain the carbon efficiency prior to instal-

lation.

Service Life

It is difficult to predict the life of any carbon filter. It

is a function of the concentration level of dust and

gaseous contamination for each specific applica-

tion. Even though sensitivity varies with the individ-

ual, the human nose is still the best indicator of the

need to change a carbon filter.

installed with, or in some cases, instead

of an existing dust filter. If the filter track

is 2” thick, it is often possible to slide in

a 1” prefilter and a 1” carbon filter.

Built-up filter banks with holding frames

are particularly easy to retrofit using

Model P fasteners. Model C carbon fil-

ters are ideal for use in the prefilter

track of the two-stage Sureseal filter

housing.

Features and Benefits

•Total detention multi-panel design combines high adsorption effi-

ciency with low pressure drop

•Entire cell is disposable so installation is clean, quick and easy

• Installation flexibility: adsorbers are suitable for both initial and

retrofit applications and in front or side access arrangements.

General

Flanders Superflow-VC Disposable Activated

Carbon Adsorbers are designed for gaseous con-

tamination control in both new and existing HVAC

systems. Superflow-VC Adsorbers have total-

detention capability with all air passing through the

carbon beds. These adsorbers can help mitigate

Indoor Air Quality problems in buildings where the

air must be cleansed of gaseous contaminants.

They are also useful in a variety of other applica-

tions such as the protection of light industrial

processes and works of art.

Construction

Superflow-VC Adsorbers consist of eight activated

carbon-filled panels arranged in a V configuration

and sealed with non-volatile adhesive into top and

bottom injection molded ABS plastic end plates.

The sealant completely eliminates bypass within

the cell. The end plates incorporate a single head-

er to position the cell in holding frames or side

access housings.

Extruded aluminum vertical struts close off the

panel edges in front and are aerodynamically

designed to minimize airflow restriction and turbu-

lence. Vertical steel rods on the downstream side

provide rigidity and minimize twisting and racking.

The activated carbon panels are constructed of

one” (25 mm) thick moisture-resistant corrugated

kraft honeycomb grids. The honeycomb is filled

with granular activated carbon held in place by fine

mesh nylon screens glued to the grid. The screens

act as a secondary prefilter and also as an afterfil-

ter. The activated carbon media is premium HVAC

grade virgin coconut shell granules with a minimum

carbon tetrachloride (CTC) activity of 60% per

ASTM D-3467. Granules are 4 x 8 US mesh size

with a minimum apparent density of 0.49 g/mL. The

minimum hardness is 97 per ASTM D-3802 and the

minimum surface area is 1100 m2/g by the N2 BET

test method.

Application Considerations

Superflow-VC Adsorbers in HVAC airstreams can

remove many gaseous contaminants thus mitigat-

ing their effects on people and processes. They are

especially useful in controlling common contami-

nants that cause poor indoor air quality (IAQ) in

commercial and industrial buildings such as office

buildings and hospitals.Typical applications and

controlled contaminants are:

Airports SOx and NOx

Blueprint facilities Ammonia

Food processing Amines

Loading docks Diesel fumes

Museums Aldehydes and acid gases

Office buildings VOCs and aldehydes

Research facilities Animal odors

Light duty IAQ applications can usually be handled

by Superflow-VC units selected at 500 fpm (2.54

m/s) face velocity with a 0.030 second residence

time. Medium and heavy duty applications include

airports, engine exhaust, some industrial processes

and situations requiring impregnated carbon. For

these applications, adsorbers should be selected at

greatly reduced face velocities for a longer resi-

dence time.

Residence Time

Residence time is the period, usually a fraction of a

second, that the contaminant molecule is within the

boundaries of the media bed depth and is exposed

to adsorption capture and (for chemisorption)

chemical change. The efficiency of an adsorber is a

function of the bed residence time for a given con-

taminant and set of environmental conditions. The

longer the residence time, the greater the efficien-

cy. Residence time is computed as: (bed area

exposed to airflow x bed depth) airflow rate.

Installation

Superflow-VC Adsorbers are not position sensitive.

Airflow may be through the header side face or the

opposite side face. The cell may be turned so that

the panels are vertical or horizontal. Wherever pos-

sible, adsorbers should be installed with panels ver-

tical and air entering the header side face.

Frames and housings used for 12” (305 mm) deep

particulate filters are well-suited for Superflow-VC

adsorbers. In new construction, built up banks of

Flanders Type 9 Holding Frames and Clips or

Flanders K-Trac Framing Modules holding prefilters

and adsorbers are often chosen where 30 inches

(760 mm) of upstream service access space is

available. Flanders Sureseal Side Access Housings

are most often used for small systems and for sys-

tems where in-line service access space is limited.

Type 9 Holding Frames include gaskets on the

flange against which the adsorber header seals.

For side access housing applications, gaskets are

applied to the side of the adsorber header to

Adsorber Protection

Particulate contamination must be considered

when utilizing gas/vapor phase adsorbers. As a

minimum, a Flanders prefilter with an efficiency of

25-30% per ASHRAE Std. 52.1 should be installed

on the upstream side of the Superflow-VC adsorber

in order to extend the service life by significantly

reducing dirt build-up. Even higher efficiency pre-

filtration should be considered when system design

allows for additional space and static pressure.

Packaging

Each Superflow-VC Adsorber is individually sealed

in a polyethylene bag prior to placement in a heavy

duty shipping carton. The bag protects the adsorber

from being expended prematurely and also facili-

tates clean and easy jobsite changeouts. The spent

adsorber can be placed in the plastic bag and then

in the carton for disposal.

Disposal

Routine disposal is usually permitted if spent adsor-

bers with Superflow-VC 201 media have been used

for normal IAQ applications. Spent adsorbers filled

with impregnated carbon and those used in indus-

trial applications may need special handling. Local

environmental authorities should be consulted prior

to disposal.

General

HMZD carbon panels are available from 3/8” to 3”

depths, and are easily installed in any existing side

or front access housing without the usual clean up

caused by carbon dusting. Bonded panels do not

need to be refilled, thus eliminating the labor asso-

ciated with transporting trays. A high initial efficien-

cy can be maintained with replacement panels

which are composed of 100% virgin carbon as

opposed to reactivated carbon.

Providing Clean Air

Indoor air quality problems found within museums,

schools, airports, semiconductor manufacturing

plants, waste water treatment facilities and hospi-

tals can be solved by using HMZD carbon panels.

They offer a carbon solution for the removal of most

specific contaminants.

Carbon Selection

HMZD carbon panels can be manufactured from

virgin carbon, where contaminant removal is

accomplished by physical adsorption or from

impregnated virgin carbon where contaminant

removal by chemical mechanisms are required.

HMZD Carbon Types and Applications:

• 201- Impregnate is virgin coconut shell carbon

for general removal of VOC’s

• 202- Caustic impregnated for removal of acid

gases

• 204- Acid impregnated for removal of alkaline

gases

• 205- Chromate impregnated for removal of

amines

• 209- Universal impregnate for removal of acid

and alkaline gases.

Carbon Usages

Activated carbon is highly effective on many

gas phase contaminants:

Pressure Drop

HMZD Panels can be incorporated into V

shaped configurations with minimal pressure

drop and impact on the system.

Please note that the breakthrough test was

based on continuous 100 ppm Hexane chal-

lenge concentration. Testing conducted at an

independent lab on virgin coconut shell car-

bon.

Efficiency

HMZD panels perform better than

loose filled systems due to increased

density of carbon and elimination of

air bypass

Carbon Selection

In general, contaminants with a

boiling point greater than 100 C

can be effectively removed with

carbon type 201.

Contaminants with a boiling

point below 100 C require other

Clean Air is Only a Block Away

Flanders, through innovative technology, has

resolved the problems associated with loose filled

activated carbon trays by introducing HMZD bond-

ed carbon panels.

HMZD stands for High Mass and Zero Dust. High

Mass refers to the greater density of activated car-

bon installed in each panel, and Zero Dust means

the filters will not release carbon dust into the air

stream. The panels are fabricated from 100% vir-

gin coconut shell activated carbon with a minimum

60% CTC activity. The premium grade carbon is

bonded together during a sintering process to form

a rigid block and framed to provide clean air.

HMZD bonded panels are replaced right at the air

handling unit with the same quality 100% virgin car-

bon as the initial installation. Standard loose filled

tray systems are typically replaced with regenerat-

ed carbon minimizing adsorption performance.

Cleaning the Air

The uniform air velocity through the bed eliminates

high velocity zones and bed fluidization. Bed flu-

idization is a major cause of continuous dusting in

loose granular system designs. HMZD bonded pan-

els are non-dusting, therefore eliminating the need

for downstream after filters.

Superior Performance

HMZD panels provide superior adsorption perform-

ance because there is no settling within the carbon

bed. The carbon granules are bonded together to

provide a uniform density of sorbent media across

the panel eliminating air bypass and stratification

zones for high efficiency and extended service life.

The panel design creates uniform air flow distribu-

tion and uniform residence time ensuring maximum

removal efficiencies.

K-Trac

Modular Filter Framing System

See model number development method on next page.

Important Features

•

Provides substantial savings in field assembly

•

Filters are tightly sealed to eliminate air bypass

•

Filters can be replaced quickly and easily

•

Modules are factory-engineered with built-in stiff-

ening

•

Construction is corrosion-resistant aluminum

General

K-Trac Filter Framing Modules are used for

ASHRAE rated filters 2” to 36” in depth. K-Trac

Modules are complete factory-designed units which

replace multiple field-erected holding frames. They

also provide inherent structural strength and leak-

proof assembly that is sometimes lacking in frame-

type installations.

K-Trac framing members are factory-cut to length,

pre-drilled and gasketed for easy and quick assem-

bly. Simple tools and light labor are all that are

required. Filters are easily inserted or removed and

require no clips or fasteners. Filters are angled into

the upper track, then set into the lower track.

Versatility

K-Trac Filter Framing Modules are available in

sizes up to a nominal 12 ft. high and 14 ft. wide for

upstream or downstream service. Modules may be

joined for larger banks. The 2” prefilter track

accepts disposable or pleated prefilters for single-

stage applications.

The primary filter track accommodates Precision

Pak bag filters, Superflow V, or Rigid-Air filters, or

other filters having nominal 1” thick headers.

Construction

K-Trac framing members are constructed of Type

6063-T5 mill-finish extruded aluminum. Clear

anodizing is available as an option. Prefilter and

primary filter tracks are factory-gasketed at the top

and bottom with polypropylene pile air seals.

Side-to-side gasketing is furnished on the filter

headers with every change. Side gaskets are com-

pressed by a positive-sealing spring-loaded com-

pression bar actuated by a sealing lever. The com-

pression bar is retracted when loading or unloading

filter elements.

Modules 8 ft. wide include one vertical support for

the upstream side. Wider modules are furnished

with vertical supports on the upstream and down-

stream sides. Sealing levers are located on the left

side of each horizontal row when facing in the

direction of air flow unless specified otherwise.

This example represents a K-Trac module, 2 filters high and 3-1/2 filters wide, upstream service and left side

levers. The letter X indicates that special features are required.

1. Height and Width Code: The first numeral represents the number of 24” x 24” filters high or wide. If 24” x 12” filters are also used in the

height or width, the second numeral is “5”.

2. Dimensions are based on using nominal size 24” x 24” and 24” x 12” filters. Select filters from capacity charts for Precision Pak bag filters

or single-headered PrecisionCell or Rigid-Air filters.

3. Sizes using 24” x 12” filters in both height and width require a 12” x 12” blankoff; for example, a KT- 15H35W has a 20 sq. ft. available,

not 21 sq. ft.

Residential Air Cleaner

Refills

For Space Gard®,Air Bear®,Honeywell®Air Cleaners*

See model numbers in chart on next page.

Media for high efficiency air cleaners

For over 50 years, Flanders air filters have been

protecting cleanrooms, hospital operating rooms

and other critical environments. Now, homes and

businesses can benefit from their superior crafts-

manship in a new line of Flanders filters.

Construction

Models 500AB, 600SG and replacement cartridges

for selected Honeywell®air cleaners are made with

a blend of polypropylene and polyethylene electro-

static filtration media which is adhered to an

expanded metal backing. This combination is deep

pleated and encased in a moisture resistant kraft

board frame and offers a MERV 8 rating.

Models 550AB and 650SG cartridges are similar to

our industrial grade PrecisionCell II air filter, with

perfectly spaced mini-pleats of wet laid glass

microfiber media and a moisture resistant kraft

board frame. This provides high efficiency filtration

and a longer filter life and a MERV 10 rating.

Model 650SG media inserts consist of the same

media as the 550AB and 650SG cartridges but are

provided in a convenient, easy to store package.

They are pleated to the proper depth with fastener

strips secured to each outside pleat.

Installation

Air Bear®replacements

Models 500AB and 550AB cartridges are designed

for use with the Trion Air Bear® air cleaner hous-

ings. Simply install in place of the Trion cartridge.

No alterations or equipment are required.

Space Gard®replacements

The Model 650 insert installs in Space Gard®mod-

els 2200 and 2250 air cleaner housings by using

the existing pleat separators and media holding

assembly. An easy-to-follow assembly guide is

printed on the package back.

Model 600SG and 650SG cartridges are also

designed for use in Space Gard®models 2200 and

2250 air cleaner housings. Designed to replace the

traditional collapsible media pack, Models 600SG

and 650SG provide all of the benefits of the origi-

nal, but with considerably less effort to install.

Model 500AB

Air Cleaner Housing

Model 82855.052025

General

The Model 500AB air cleaner housing is designed

for use with the Model 500AB or 550AB cartridge in

an HVAC system. Both of these cartridges feature

deep pleated media whose area is several times

the face area of the housing.

With the advent of modern air tight buildings, many

of us spend our indoor hours in air that can literally

make us feel sick with the recirculation of dirt, dust

pollen, animal dander, and other particulates. It is

for this reason that state-of-the-art air filtration is

essential. Flanders Model 500AB air cleaners offer

a solution you can trust, backed by nearly 50 years

of filtration manufacturing experience.

The non-woven media inserts capture a wide range

of airborne particles as small as 1 micron (1/25,000

of an inch in diameter). These airborne particles

include grease and soot (5 microns), dust (10

microns), pollen and mold (100 microns) which are

commonly found in homes. This type of filtration

not only provides cleaner air but keeps these parti-

cles from building up on cooling and heating equip-

ment.

Construction

The Model 500AB air cleaner housing has a built-in

prefilter track. Using a prefilter can greatly increase

the useful life of a high efficiency filter such as the

500AB or 550AB cartridges. The Model 500AB air

cleaner housing takes a standard 20 x 25 x 1 dis-

posable panel filter as a prefilter.

Dimensions

Important Features

• Allows better filtration and less

maintenance

•Rugged metal construction

•Prefilter track for particulate or gas/vapor

control
