Q Fan

The Model Q™ fan is a quiet, airfoil, in-

line fan specifically designed for air

conditioning applications. This highly

refined axial flow fan is available in 13

sizes from 1,000 through 80,000 cfm.

Small and compact, the Q fan has

proven to be the ideal air moving

device for standalone applications and

also for custom air handling units. It

can be used for supply, return and

exhaust systems.

Available in arrangement 1 (for floor

mounting of larger units with heavier

motors) and arrangement 9 (horizontal

or vertical mounting), it can be selected

in class 1, 2 and 3. Arrangement 9

permits factory mounting of the motor

on top, bottom, or either side of the fan

— see below.

Benefits

• The Q (Quiet) Fan

The Trane Model Q fan generates less

low frequency noise (more difficult to

attenuate) than any other type of fan in

the HVAC industry. Sound level

comparisons show common vaneaxial

fans produce up to 23 db higher sound

levels than the Model Q — significant

in industrial applications. Being quieter

than centrifugal fans allows for

installations closer to building

occupants.

• Saves Mechanical Room Space

The compact quiet Q fan saves floor

space, which reduces system first cost.

• Easy To Install

Rigging and installation is so much

quicker and easier that total installed

cost savings are typically five percent

or more.

• Low Maintenance

Belt-driven with fixed blades, Model Q

fan has very few moving parts. This

design results in exceptionally low

maintenance requirements. No fan

teardowns need be scheduled. In fact,

Q fans installed 25 years ago are still

operating just as quietly as when they

were installed.

Super Q II Plus

More than twenty years after the

introduction of the Model Q™, it still

retains its reputation as one of the

quietest HVAC fans in the world. This

tradition of excellence continues with

the introduction of a new Q fan

acoustical enclosure and duct silencer

so effective and so compact that we

named it the Super Q II.

Super Q II Fan

Available with Model Q fans from 1,000

to 43,000 cfm, the Super Q II enclosure

inhibits radiated fan and motor noise

from entering the surrounding space. It

internally isolates the fan on high

deflection spring isolators so ductwork

can be connected directly to the

enclosure. It is uniquely designed to be

floor or ceiling mounted with ease.

Although the Model Q needs very little

maintenance, future maintenance

requirements were considered by

Super Q II designers. Every unit has the

bearing grease lines extended through

the casing and every unit has two full

size access panels that provide

complete access to all internal

components.

Variable Air Volume Compatible

The Super Q fan is modulated for VAV

with variable frequency drives (by

others), not with inlet vanes. Variable

speed inverter fan modulation offers

exceptional energy saving and

exceptionally quiet part load operation.

VAV variable speed Q fans are

structurally reinforced to handle the

uneven harmonic loadings associated

with variable speed fan operation. In

addition, the factory gives variable

speed Q fans a precise, 10-point

balance to further help assure trouble-

free operation. Only constant pitch

drives should be used with variable

frequency inverters.

Super Q II Accessories

• Inlet screen — safety accessory

mounted to fan inlet. Heavy, plated

steel wire

• Inlet bellmouth — used with unducted

or plenum applications. Improves air

flow and reduces noise.

• Inlet silencer (long or short) — rigid

connection to Super Q fan

• Outlet flow stabilization screen — small

mesh outlet screen. Helps offset effect

of poor outlet airflow conditions

• Outlet silencer (short or long) — flex

connected to Q fan

• Variable frequency inverter balancing

and reinforcement (frequency inverter

by others). This option requires

constant pitch drives.

• Outlet screen — safety accessory

mounted to fan outlet. Heavy, plated

steel wire.

Trane Plus Duct Silencer

The Plus option is a high performance

duct silencer. Designed specifically for

the Super Q II and Model Q™, it has

several unique features that reduce

airborne noise and turbulence to

exceptionally low levels. Briefly, the

Plus option develops maximum static

regain while simultaneously limiting

objectionable mid and high frequency

noise. The Plus option should be used

whenever quiet comfort is desired

and the duct system is acoustically

unable to provide it.

Trane’s Plus Silencer provides

significant noise attenuation, up to

32 db at 1,000 Hz, without a significant

increase in fan horsepower

requirements.

Plus Silencer

The modular, component design

approach of the Super Q II air handling

system makes it exceptionally well

suited for renovation, retrofit and

replacement projects. The Super Q II air

handling system components (fan,

silencers, filter/coil module, etc.) fit

through most doors and elevators and

can be easily field-assembled into any

system configuration (blow-thru, draw-

thru, etc.).

By carrying the concept of noise source

attenuation to its economic maximum,

Trane has created a fan system that can

move significant amounts of air

without creating objectionable low

frequency rumble. It provides proven

acoustical performance with less

design risk. In project after project, the

Trane Model Q fan has been the key to

creating NC 15 to NC 35 quiet

comfort jobs.

Beyond quiet, the Super Q II Plus

system is small and compact. In fact, it

is small and quiet enough that it can be

successfully installed in ceiling

plenums. Locating a Super Q II Plus in

the plenum helps reduce and even

eliminate the floor space needed for

the mechanical room.

Features

and Benefits

The low sound and high performance

of the Trane Model Q™ fan are achieved

by reducing noise-creating, energy-

consuming turbulence within the fan.

Airflow research and development

techniques employed were similar to

those used in perfecting today’s high

performance axial flow jet engine

compressors. The resulting smooth air

path has made the Model Q the first

vaneaxial fan to provide quiet, efficient

operation, suitable for air conditioning

duty.

Aerodynamic Air Path

A component by component analysis

of the Model Q points to 12

aerodynamic features which are keys

to a smooth air path. Starting at the

inlet, the struts [1] of the patented

bearing support are precisely

positioned in relation to the fan blades.

Air passing over the struts strikes the

blades in a pattern that prevents blade

whine.

The aerodynamically shaped inlet bell

[2] and inlet cone [3] provide uniform

axial flow parallel to the fan shaft. Air is

delivered equally to the leading edge of

the fan blades — no crowding toward

the fan tips.

Air separation is reduced by the

precision cast aluminum airfoil cross

section [4] of the fan blades. Blade pitch

[5], using a variable angle of attack in

the radial dimensions, is precisely

controlled to prevent energy loss.

Exceptionally close clearance

[6] between the blade tips and housing

reduces the eddy currents of fan tip

recirculation. The reinforcing ring

rigidizes the housing to maintain the tip

clearance. The interior of the fan wheel

is insulated to prevent hub

strengthening protrusions from

[7] windmilling in the airstream.

A precisely controlled space [8]

between the fan blades and diffuser

vanes is necessary to allow airflow

stabilization ahead of the vanes. The

vanes themselves are precision cast

aluminum and have an airfoil cross

section [9] and a precise radial pitch

[10]. This provides smooth, spiral-free

discharge.

The diffuser section design [11] is

critical. A precisely determined

diffusion angle produces the greatest

possible static regain within the

confines of the fan. An end cone

[12) covers the fan drive assembly,

thereby reducing the turbulence

generated by air passing over exposed

drives.

Precise Manufacturing Assures

Performance — Advanced

manufacturing techniques assure the

same performance characteristics for

each production Model Q fan.

•Fin Struts — The fin struts of the

patented bearing support are precisely

positioned in relation to the fan blade.

Air passing over the struts strikes the

plate in a pattern that prevents the

irritating whine, from blade frequency,

which is characteristic of industrial

vaneaxials.

•Inlet Bell and Cone — The

aerodynamically shaped inlet bell and

inlet cone provide uniform axial flow

into the fan parallel with the fan shaft.

Air is delivered equally to the leading

edge of the fan blades. This prevents

crowding toward the blade tip.

•Wheel — The wheel consists of 8

precision cast blades with a twisted

radially projected shape and airfoil

cross section. This radial projection

utilizes a variable angle of attack in the

radial dimension and prevents radial

movement as the air particles move

through the wheel.

•Tip Clearance — Close clearance

between the blade tips and housing

reduces eddy currents due to tip

recirculation. The reinforcing ring holds

the housing in its precise shape to

maintain proper clearance.

•Vane Spacing — Precise space

between the fan blades and the diffuser

vanes is necessary to allow flow

stabilization ahead of the vanes. The 29

diffuser vanes also have an airfoil cross

section and a twisted, radially projected

shape. This provides smooth, spiral-

free air discharge.

•Precision Cast Aluminum Fan and

Diffuser — Being cast, blade and vane

shapes are permanently and precisely

fixed. They are not subject to

misalignment or distortion as are

welded, sheet metal forms.

•Diffuser Section — The diffuser

section design is critical. A precisely

determined flare angle at the diffuser

end produces the greatest possible

static regain within the confines of the

fan. Thus, externally mounted diffuser

accessories, common for industrial

vaneaxials, are not necessary.

•Hydraulically Expanded Flow-

Formed Housing — In this process,

the cylindrical housing is drawn to its

final form over an expansion die. The

metal, expanded beyond its elastic

limit, permanently retains the precision

form imparted by the die.

•Ductile Weld Technique — This

technique is required for the fan

housing seam to guarantee success of

the expansion forming process. The arc

and “puddle” are submerged in

molten flux that shields the weld

material from oxidation. This prevents

brittleness and also anneals the weld.

The result is a flexible, ductile seam

capable of being drawn and formed —

another example of the advanced

technology used in the Trane Model

Q fan.

Features

and Benefits

The Trane Model Q™ and Super Q II

fans can help you maximize your

building’s usable floor space by using

them in place of centrifugal fans. The

smaller the equipment room, the more

space left for tenants, merchandise, etc.

Saving Valuable

Equipment Room Space

Return or Exhaust Applications

Figure F-1 shows a size 44, single

width, low pressure airfoil centrifugal

fan delivering 20,000 cfm of air.

Because of its size and weight, it is floor

mounted and connected to a return air

plenum. In contrast, a 44-inch Model Q

fan is used in Figure F-2 instead of a

centrifugal fan. Its smaller size and

lighter weight permits ceiling

suspension and approximately 75 sq ft

of floor space is freed up for other use.

Draw-Thru Supply Application

(Small Capacity)

The fan system in Figure F-3 is a

27-inch, single width, medium pressure

airfoil centrifugal fan rated at 9,000 cfm.

Even though it is a relatively small fan,

it is floor mounted beside the coil bank

plenum. Figure F-4 shows a 27-inch

Model Q substituted in place of the

centrifugal. The small size and weight,

plus the installation flexibility of the

Model Q, permits mounting in a

vertical position on top of the plenum.

The space savings is about 25 sq ft.

Features

and Benefits

Draw-Thru Supply Application

(Large Capacity)

A 60-inch, single-width, medium

pressure airfoil centrifugal fan is used

in the system illustrated in Figure F-5 to

supply 45,000 cfm of air. This capacity

can be easily achieved by installing a

pair of 40-inch Model Q™ fans in

parallel as shown in Figure F-6. The

resulting floor space savings is

approximately 85 sq ft!

Blow-Thru Supply Application

Figure F-7 shows a typical medium

pressure, built-up, blow-thru system.

The fan, enclosed in a plenum, is a 33-

inch, double width, airfoil centrifugal

that delivers 30,000 cfm of air. The

bulkiness of the plenum is dictated by

the necessary clearances around the

fan. To save floor space, a 44-inch

Model Q replaces the centrifugal in

Figure F-8. The suspended mounting of

the Model Q frees about 70 sq ft for

installation of pumps and other

equipment.

11

Features

and Benefits

The Trane Model Q™ fan, with all its

precision and quality, is still a cost

effective fan. When all necessary

system components are considered, it

provides substantial installation cost

savings. In addition, its small size and

variable mounting positions allow

more freedom to the designer and

installer.

First Cost Comparisons

True first cost is the total cost of an

operable installation. With the Trane

Model Q, this consists of only the fan,

drive and isolation. By comparison, the

airfoil centrifugal typically requires

these three components, plus an

integral base. In addition, cost of

isolation for the airfoil is greater

because it is typically twice as heavy as

the Model Q.

The common vaneaxial also requires

more components in most

applications. Besides the fan, drive and

isolation, an inlet bell and diffuser are

frequently necessary to meet cataloged

performance. A sound attenuator is

also required to reduce noise to a level

equivalent to a Model Q fan without

attenuation.

Reduce Installed Cost

By Up To 20 Percent

Lower Installation Costs

The Trane Model Q fan has fewer

components to install and the

advantage of lighter weight. With only

half the weight of airfoil and tubular

centrifugals, it requires less manpower

for rigging and setting the fan in place.

The result is reduced labor, with

corresponding dollar savings on the

typical job.

Lighter weight also reduces inertia pad

requirements. With the Model Q, a pad

has to be considered only on large

requires purchase of motor, motor

rails, belt guard and isolation in

addition to the basic fan.

Arrangement 3 airfoil centrifugal fan

requires purchase of motor, belt

guard, motor slide rail, isolation and

subbase in addition to basic fan.

Class III fans. Airfoil and tubular

centrifugals, because of greater weight,

often require pads for Class I and II to

minimize the effect imposed by normal

vibration.

Combined Saving Significant

A comparison of average total installed

cost is shown in Table F-1. Average cost

figures were developed based on

estimates by experienced installing

contractors. In all cases, the Trane

Model Q represents a significant

savings.

The System

An air system may consist of a fan,

ductwork, air control dampers, cooling

coils, heating coils, filters, diffusers,

noise attenuation, turning vanes, etc.

The fan is the component in the system

which provides energy to the airstream

to overcome the resistance to flow of

the other components.

System Component Losses

Every system has a combined

resistance to flow which is usually

different from every other system and

is dependent upon the individual

components in the system. The

determination of the “pressure loss” or

“resistance to flow,” for the individual

components can be obtained from the

component manufacturers. The

determination of pressure losses for

ductwork and branch piping design is

well documented in standard

handbooks such as the ASHRAE

Handbook of Fundamentals.

System Curve

At a fixed volume flow rate (cfm)

through a given air system, a

corresponding pressure loss, or

resistance to this flow, will exist. If the

flow rate is changed, the resulting

pressure loss, or resistance to flow, will

also change. The relationship

governing this change for most

systems is:

PRESSUREc/PRESSURE = (CFMc/CFM)2

The characteristic curve of a typical

“fixed system” plots as a parabola in

accordance with the above

relationship. Typical plots of the

resistance to flow versus volume flow

rate are shown with normalized duct

system curves, Figure A-1.

For a fixed system, an increase or

decrease in system resistance results

from an increase or decrease in the

volume flow rate along the given

system curve only.

Refer to Duct System A, Figure A-1.

Assume a system design point at

100 percent volume and 100 percent

resistance. If the volume flow rate is

increased to 120 percent of design

volume, the system resistance will

increase to 144 percent of the design

resistance in accordance with the

system equation. A further increase in

volume results in a corresponding

increase in system pressure. A

decrease in volume flow to 50 percent

results in a 75 percent reduction in

design resistance.

Application

Considerations

Performance Data Determination

The fan performance section of this

catalog contains a fan performance

table and fan curve for each fan size.

The performance data contained in this

catalog was calculated from tests

conducted in accordance with AMCA

Standard 210 Laboratory Methods of

Testing Fans for Rating.

The AMCA test procedure uses an

open inlet and 10 wheel diameters of

straight discharge ductwork to assure

maximum static regain. The fan is

direct driven by a dynamometer.

The fan performance tables in this

catalog are based upon standard air:

0.075 lbs/ft3 (70 F, barometric pressure

29.92-inches Hg).

Fan Performance Curves

A fan performance curve is a graphical

presentation of the performance of a

fan. Usually it covers the entire range

from free delivery (wide open cfm, no

obstruction to flow) to no delivery

(blocked tight, an airtight system with

no air flowing).

The point of intersection of the system

curve and the fan performance curve

determines the point of operation and

actual flow volume. If the system

resistance has been accurately

determined and the fan properly

selected, their performance curves will

intersect at the design flow rate. Refer

to Figure A-2. The normalized Duct

System A from Figure A-1 has been

plotted with a normalized fan

performance curve.

Temperature and Altitude Corrections

The fan performance values in the

tables and curves of this catalog are

based on standard air (.075 lbs/ft3). If

the airflow requirement for a particular

job is stated in terms of nonstandard

air, a density correction needs to be

made before selecting the fan. It is

important to also note that most air

friction charts for ducts, filters, coils,

etc. are also based on standard air and

corrections must be made to determine

proper losses at other conditions.

Figure A-3 illustrates the ratio of air

densities to standard air at various

temperatures and elevations. A Q fan is

designed for operation between -20 F

and 150 F only.

Figure A-2 — Point of Operation — Interaction of the System Curve

and the Fan Performance Curve

Figure A-3 — Air Density Corrections

15

The following is the procedure to use

when selecting a fan for elevations and

temperatures other than standard:

1

Determine the air density from

Figure A-3.

2

Divide static pressure at the non-

standard condition by the air density

ratio.

3

Use the actual cfm and corrected static

pressure to determine rpm and bhp

from the fan performance tables.

4

The rpm is correct as selected.

5

The bhp must be multiplied by the air

density ratio determined in step one to

get the actual operating bhp.

Option and Installation Kt Corrections

System effect losses due to less than

ideal inlet or outlet configuration can be

expressed in terms of velocity pressure

by the following expression:

Inlet SP Loss =

Kti

(

Inlet Velocity

)

2

4005

Where Kti =

Inlet Option Kt + Inlet Installation Kt

Outlet SP Loss =

Kto

(

Outlet Velocity

)

2

4005

Where Kto = Outlet Option Kt + Outlet

Installation Kt

Kt is the loss factor for the inlet or

discharge condition being considered.

It is necessary to add all of the static

pressure loss determined from the

above equation to the component

static pressure to determine the point

of duty static pressure for selection of

the fan.

Fan Option Kt Corrections

The fan static pressure should be

adjusted for fan options. Option

pressure drops are documented as Kt

losses and are handled the same way

as installation Kt effects (losses). Use

Table A-1, Q Fan/Super Q II Fan Kt

corrections, to determine the Kt values.

Add these values to any installation Kt

values. Use the result to select the fan.

Q and Super Q II Fan Modulation —

AC Inverter Capacity Control

Q fans and Super Q II fans can be

modulated with AC frequency drives.

The Trane Company recommends

Magnetek low noise inverter drives and

Century high efficiency motors for

optimum modulation performance.

Operating the Q or Super Q II fan on AC

frequency drives requires the Q fan to

be strengthened and balanced in the

factory. This option “beefs up” the

mechanical bracing of the Q fan inlet

bearing assembly and calls for a

precision factory balance. Precision

balancing covers 10 operating points

on the system curve from 10 percent

load to full load.

Minimum cfm with AC inverters —

Above 1.5” static pressure, the

minimum cfm is the surge (do not

select) line. Below 1.5” static pressure,

it is 1000 cfm.

Q Fan Modulation — Inlet Vanes

Inlet vanes are a widely used form of

fan modulation. As inlet vanes close,

they impart a spin on the incoming air

in the direction of the fan wheel

rotation. This reduces airflow, static

pressure and brake horsepower.

However, inlet vanes do increase

sound levels. If a job is acoustically

sensitive, AC inverters are

recommended for modulation. As

shown in Figure A-5, a separate cfm

static pressure curve (cfm-sp) is

generated per each inlet vane position.

Likewise, the figure shows brake

horsepower curves that apply for

various inlet vane positions.

Inlet vanes are controlled by placing a

static pressure sensor in the

downstream ductwork, typically about

two-thirds of the way down the longest

trunk duct. This sensor is set at a static

pressure that will ensure sufficient

pressure is available to move air from

that point through the remaining duct

work. The sensor will respond to duct

pressure changes and signal the inlet

vane operator to open or close the

vanes to maintain the control setting at

the sensor location.

As VAV terminal units begin to close in

response to a decreasing cooling load,

static pressure in the ductwork

increases. This causes the fan

operating point to temporarily move

upward to the left on a constant rpm

curve as shown in Figure A-5 (point A

to point B). The static pressure sensor

will detect an increase in duct pressure

and signal the inlet vane operator to

begin to close the vanes. The inlet

vanes will close until the static pressure

sensor is again satisfied, moving the

operation point to C (Figure A-5). As the

cooling load continues to decrease, the

modulation curve will be formed

(point C to D, and point D to E) on

Figure A-5. This curve passes through

the design point and through the static

pressure sensor control point. The

static pressure of any point on this

curve can be calculated using the

formula:

Sp = (Cfm/Cfmd)2 x (SPd-SPc) = SPc

SPd = static pressure at design,

SPc = static pressure control setting,

Cfmd = cfm at design.

The VAV system modulation curve can

be drawn using a Trane system

modulation overlay. The axis of the

overlay is placed on a static pressure

control setting. The curve that

intersects the design points is the

system modulation curve.

Because the axes of the inlet vane

performance graph are in terms of

percent wide open cfm (wocfm)

and percent peak static pressure, the

first step in establishing the system

modulation curve is to find the

proper design points. By plotting the

design point on the performance

curve for the fan in question, one can

easily determine the percent wocfm.

Knowing this, plot a point on the

cfm-sp curve (Figure A-6) for inlet

vanes wide open, at the design point

of wocfm. By tracing to the left, one can

determine the percent of peak static

pressure. By knowing the design cfm,

static pressure and the percent of wide

open cfm and percent peak static that

these values represent, one can

calculate wocfm and peak static

pressure.

Figure A-5 – VAV System Modulation Curve

17

Application

Considerations

The control static pressure can then be

expressed as a percent of peak static

pressure and plotted. The system

modulation curve is described by the

curve on the modulation overlay that

passes through the design point when

the axis is placed on the control static

pressure point.

The minimum inlet vane cfm can easily

be determined after the system

modulation has been established. It

will be one of two things, either a) the

point where the system modulation

curve intersects the surge line, or

b) 40 percent wocfm, whichever is

greater. Forty percent wocfm is the

minimum point a Q fan with inlet vanes

can modulate, due to inherent

instability that results when the vanes

close to a certain angle.

A plot of part load cfm versus brake

horsepower can also be made after the

system modulation curve is established.

At each intersection of the system

modulation curve with a cfm-sp curve

for a certain inlet vane opening, a

vertical line is traced to the appropriate

bhp-cfm curve. At each intersection of a

bhp-cfm curve, a horizontal line is

traced to the scale of percent brake

horsepower. This will lead to a percent

wocfm versus percent peak bhp plot.

The design rpm and bhp need to be

corrected to account for performance

losses due to inlet vanes being in the air

stream. A correction of one percent to

the rpm and three percent to the bhp is

made in order to get to design

conditions with the inlet vanes fully

open.

Part load fan power consumption with

inlet vanes can be determined by

entering Figure A-6 at the desired

percent wide open cfm. (Wide open

cfm is found on the fan curve by

following the fan rpm to the right until

it intersects the 0” static pressure axis.)

On Figure A-6, plot a system curve from

the control static pressure through the

point of operation defined as a

calculated percent wide open cfm. Read

vertically upward from the 25, 50 and 75

percent intersections to determine the

percent bhp at part load.

Intermediate operating points are found

by extrapolation. Inlet vanes increase

Q fan sound levels. See Table A-5.

Figure A-6 – Inlet Vane Performance

18

Application

Considerations

Parallel Fan Operation

The Q fan performance curve has a

characteristic shape where two

different cfm’s are possible at the same

static pressure. Therefore, when

selecting fans for multiple installation

connected with either a common inlet,

a common discharge or both, care

must be taken to eliminate the

possibility of fan paralleling.

Figure A-7 shows two typical cfm-sp

performance curves for the Q fan. Fan

paralleling can occur when multiple

fans are selected in the shaded area.

The shaded area is determined by

going straight across from the lowest

point of the fan performance curve at

the left of the surge line (A and A1) to

the same curve to the right of the surge

line (B and B1). Points B and B1 fall on a

constant system curve.

Motor and Drive Selection

The Model Q fan has been designed for

use with NEMA “T” Frame

motors. Motor hp limits for Class I, II,

and III construction are listed in the

roughing-in Dimensional Data section

of this catalog.

Minimizing belt tension forces

increases bearing life and reduces fan

noise. The Q fan and Super Q II fan

drive selection is totally computerized

by the factory to achieve quiet, long life

operation. If Trane provides Q fan

drives, all fan motor information must

be made available to the Trane sales

engineer.

Table A-4 defines this constant

system curve as a percent of wide-

open cfm. If fans in parallel are

always operated to the right of this

constant system curve, fan paralleling

will not occur.

Considerations

Operating Cost/Efficiency

The quiet Q fan is a very efficient fan.

The Q fan mixed-flow type airfoil thrust

blades offer outstanding efficiency and

operating cost savings over such fan

types as plug fans. Designers can

compare the Q fan efficiency with other

fans by using the fan selection program

and the Trane Customer Direct Service

(C.D.S.™) Network FanMod program.

The Trane fan selection program

provides accurate part load energy

consumption no matter what fan

modulation method is selected. The

FanMod program compares two or

more fans economically for one or

more years. FanMod is an easy-to-use

program for equipment life cycle cost

analysis.

When comparing the Q fan

performance with centrifugal fans,

remember to recalculate the fan

external static pressure. The in-line

delivery of the Q fan often eliminates

the need for a 90 degree turn right off

the fan outlet. Turns directly

downstream of the fan outlet consume

energy and generate noise and,

therefore, should be avoided whenever

possible.

Q Fan Sound Data

Trane Q fans are designed to be used in

any installation where a standard airfoil

centrifugal fan can be used. The sound

level of the Q fan in the difficult to

attenuate lower frequencies is lower

than that produced by standard airfoil

centrifugal fans with the same capacity.

Sound levels in the higher octave

bands compare favorably. Therefore,

the Q fan will provide quieter sound

levels in a typical installation.

Designing the system for lower static

pressures and selecting the fan at high

efficiency will result in quieter fan

operation, as well as power savings.

The best method of acoustical design

makes use of unit sound power levels

in all eight octave bands. These sound

power levels for each Trane Q fan can

be obtained from the Trane

computerized fan selection program.

In the past, it has been an industry

practice to test air moving devices

within a reverberating room to

determine total sound power. This has

presented the problem of

distinguishing between inlet and

discharge sound power ratings, where

significant differences do exist.

Trane engineers solved this problem by

locating the fan adjacent to the

reverberating room and ducting to it.

By turning the fan around, inlet and

discharge sound power can be

measured separately and accurately.

By ducting both the inlet and outlet,

radiated shell sound power was

determined. Using this method with

the Trane reverberant room that

conforms to ASHRAE standards,

acoustical data on the Q fan is

substantially more accurate than fan

ratings made using conventional

techniques. Tests covered all sizes and

speeds over the entire performance

range of the line. A computer program

was then used to determine the precise

relationship of speed, size, point of

operation and frequency.

Plus silencer attenuation is shown in

Tables S-1 and S-2. Use the Trane fan

selection program to obtain precise

Plus attenuation with regenerated

noise included.

Trane ASA10B Sound Analyzer

Trane offers a low cost 10 octave

band sound analyzer for sound

measurements. Capable of measuring

noise from 30 to 123 db sound

pressure with flat, dbA and dbC sound

LCb weightings this rugged meter

permits comparative and absolute

sound measurements to be taken.

Ideas On How To Use The ASA10B

The ASA10B can be used on existing

jobs to measure equipment sound

levels by octave bands. Compare this

data with NC charts to determine what

frequencies need to be attenuated and

by how much. The type and cost of

noise control options is a function of

the problem

frequency and amplitude.

On acoustical retrofits, the ASA10B can

accurately compare before and after

noise levels. Real measurements

establish the benefit of the retrofit.

Trane Acoustics Program

Trane has a system level acoustics

computer program that accurately

converts fan sound power to room NC

levels. This program uses ASHRAE

approved algorithms and is the most

complete and accurate sound predictive

program in the HVAC industry. Use of

the Trane acoustics program allows all

sound paths to be checked and

attenuated to achieve the desired room

sound levels without costly

overdesigning. Contact your Trane sales

engineer for more details on this

Customer Direct Service (C.D.S.)

Network program.

Q Fan/Super Q II Plus Silencers

Trane has a unique silencer for the

Q fan. This low turbulence, high

attenuation silencer dramatically

reduces airborne noise from the Q-Fan.

A bulleted cylindrical silencer attenuates

medium and high frequency noise

generated by the Q Fan to a point where

the Q Fan can be successfully installed

in such sound sensitive applications as

ceiling plenums successfully.

Trane’s Plus silencer has a field

repositionable bullet (center body) that

can be relocated close to the Q Fan

outlet. This unique feature eliminates

low frequency turbulence and makes

the Q fan quieter than plug fans or other

axial or mixed flow fans. Pressure drop

through the Plus silencer is

approximately .1-inch sp. The Plus

silencer has been used on many

projects in the last five years to

consistently create NC 15-35 spaces.

If inlet vane modulation was selected,

increase the rpm by 1 percent and

increase the bhp by 3 percent.

10

If the air density ratio is nonstandard

(different than 1.00), the rpm is correct

and the bhp must be multiplied by the

Q FAN ASSEMBLY

Housing

Housings are 14-gauge steel

hydraulically expanded to form

integral inlet bell and diffuser sections.

Hydraulically expanded stiffening ring

welded in area of wheel raceway. On

VAV variable speed fan units, fan inlet

supports are structurally reinforced to

handle extra stresses of variable speed

fan modulation and fan is balanced at

ten different fan speeds over the

desired operating range.

Inlet/Outlet Shells

Fan has tapered inlet and outlet

shells over fan hub assembly. Shells

uniformly accelerate air through

blade area. End bell covers fan drive

assembly, thereby reducing flow

turbulence. Eight fan blades are

precision aluminum casting with airfoil

cross sections. Blade to shell clearance

is in the range of 30 mils.

Fan Wheel

Fans size 16-44 have fan wheel of

precision aluminum casting with eight

radially projected blades with air-foil

cross sections.

Fans size 49-60 have fan wheel of

sixteen precision cast and machined

aluminum blades mounted on a steel

wheel plate.

All wheels are dynamically balanced

and keyed to fan shaft.

Diffuser

Cast aluminum diffuser with 29 radially

projected straightening vanes with

airfoil cross sections. Leading edge of

vanes are curved to reduce tone noise

generation. Clips on almost every other

vane eliminate harmonic ring potential.

Shaft

Solid AISI-C1040 hot-rolled steel, turned

and polished. Close tolerances

maintained where shaft makes contact

with bearings.

Bearings

Precision, flange-mounted, self-aligning

ball bearings at inlet and discharge.

Bearings on all sizes are grease

lubricated and selected for a minimum

average life (AFBMA L-50) in excess of

200,000 hours at maximum cataloged

operating conditions. Bearing

greaselines are extended out through

fan shell for easy servicing.

Mechanical

Specifications

Drives

Mechanical drives are computer

selected for low noise, low

maintenance operation. Center

distance and arc of contact is

maintained within prefixed limits.

Constant speed fans use variable or

constant pitch drives; variable speed

modulated fans use fixed drives only.

SUPER QUIET II FANS

Trane Super Quiet II (SQ2) fans include

fan housing, wheel, shaft, bearings,

diffuser section, motor mounting

support, ODP standard or high

efficiency motor, drives, spring

isolation in acoustically-treated casing

in a factory-assembled unit. Fan motors

are outside of airstream.

Constant volume units (SQ2C) are

equipped with variable or constant

pitch drives. Variable air volume units

(SQ2V) use adjustable frequency

inverters for fan capacity modulation

and must have constant pitch drives.

Inlet vanes are NOT available for

Super Q II fans.

ENCLOSURE

Fans are internally isolated on four

height saving spring isolators and

then flex connected inside of an airtight

acoustical enclosure. Walls are

16-gauge steel, internally lined with

two-inch thick three-pound per

square foot density fiberglass. Airside

surface of acoustical lining is coated

with black matte faced lining to prevent

scuffing.

Enclosure has two large full size

side access panels. Access panels are

fully gasketed and mechanically

attached to casing for easy removal.

Enclosure has access panel positioning

feet to insure easy access panel

replacement after removal.

Duct connections in enclosure end

panels slip connect to standard U.S.

round duct sizes.

Fan grease lines are extended through

enclosure for easy servicing of fan.

Optional fan motor leads are extended

through casing for easier installation.

Two rails support the entire enclosure.

Rails can be rested on floor or hung

from the ceiling with steel rods. Ducts

can be directly connected to enclosure

since fan is internally isolated.

Enclosure is rated for four-inch

negative or five-inch positive pressure.

ACCESSORIES

Inlet Screen (Q, SQ2)

Heavy-gauge steel wire mesh.

Inlet Bellmouth (Q, SQ2)

On unducted inlets, the radius

bellmouth uniformly accelerates air

into the fan, reducing noise and energy

requirements.

Plus Duct Silencer (Q, SQ2)

Significantly attenuates fan airborne

sound levels. Center body of round

silencer is dimensional matched to

Q-fan hub. Center body is field

adjustable in the direction of airflow.

This allows hub to be located close to

Q-fan, thereby reducing flow

generated turbulence and noise.

Silencers can be on inlet and/or outlet

and come in short and long length

versions. Silencers are flex connected

to Q fans and slip connected directly to

Super Q II enclosures. Silencers are

shipped loose for field installation.

Inlet Flange (Q)

Rolled steel ring, factory-mounted, for

flanged duct connection. Sizes 16 to 21

one-inch flanges, sizes 27 to 44 are

1½-inch flanges.

Adjustable Inlet Vanes

11 steel vanes operated by a positive

peripheral control mechanism located

out of the airstream. Each vane is

supported at both ends by a precision

bronze bearing. The control arm is

suitable for manual or automatic

operation. Inlet vanes are shipped

loose for field installation.

Mechanical

Specifications

Outlet Flange (Q)

Rolled steel ring, factory-mounted, for

flanged duct connection.

Outlet Diffuser (Equalizer) (Q)

Steel spinning with 30 degree included

diffusion angle. Permit same size slip-

duct connection on discharge as inlet.

Outlet Screen (Q)

Heavy-gauge steel wire mesh.

Outlet Flow Stabilization

Screen (Q, SQ2)

Similar to outlet screen, but openings

are much smaller. Designed to act as

an airflow stabilization device on the

outlet of each fan.

Since The Trane Company has a policy of continuous

product improvement, it reserves the right to change

design and specification without notice.
