Severe Duty Options

Seismic

With changes in

building codes

and standards,

more equipment

is required to

be seismically

certified in areas

of the country not

commonly thought of

as being in seismically active zones.

The International Building Code (IBC) is designed

to provide model code regulations that safeguard

public health and safety in all U.S. communities.

The IBC 2009 is the latest version adopted on state

or local levels. With this code, the standards are

intended to improve the performance and design of

non-structural systems subject to seismic events.

The State of California, one of the most active

seismic areas in the United States, has the Office

of Statewide Health Planning and Development

(OSHPD). OSHPD regulates the design and

construction of healthcare facilities to ensure they

are safe and capable of providing services to the

public after a seismic event. OSHPD developed

their own unique certification process to incorporate

the IBC and ASCE testing standards to ensure

equipment remains operable after a seismic event.

Protocols designed for seismic standards:

Seismic

Testing

Criteria

All Greenheck seismically certified models

have been tested using the most severe

seismic event that is found on the Spectral

Response Map per IBC Figures 1613.5

(1-2). Because our testing is performed

under the worst case scenario, using the

highest mapped seismic load, highest level

occupancy category, worst case site class,

and highest code mandated importance

factor, this allows Greenheck seismically

certified fans to be used anywhere in the

United States under any conditions.

California

OSHPD Test

Protocols

The California Office of Statewide Health

Planning and Development (OSHPD)

requires all certified models be shake table

tested in accordance with ICC ES AC-156,

in which the fans are physically subjected

to the same or greater forces than they

will see during a seismic event. Subjecting

Greenheck models SWB, SFD and SFB fans

to this type of testing ensures the fans will

operate without problems after a seismic

event. (OSP-0113-10 - SWB Series 100 and

200 SFB, SFD)

Certified

Independent

Third-Party

Testing

All Greenheck seismically certified fan

models have gone through extensive

testing procedures. Greenheck models

SWB, SFD and SFB have been certified to

IBC 2006, 2009, ASCE 7-05 and California

OSHPD standards through both engineering

calculations and shake table testing by

independent third party engineering firms.

(SWB Series 100 and 200, SFB and SFD)

Protocols designed to protect against

wind borne debris and severe wind loads:

Miami-Dade

County Test

Protocols

Greenheck worked with Miami-Dade

County to outline a high velocity hurricane

zone standard for rooftop fans. The SFD,

SFB and SWB Series 100 and 200 have

been certified by an independent third

party to the ASTM E-330 Static Pressure

Difference Standard, Florida Building

Code Test Protocol TAS-201 (large missile

impact), 202 (static pressure difference)

and 203 (cyclic pressure) Static Pressure

Florida

Product

Approval

Florida Product Approval ensures that

products which have been approved can

be used anywhere in the State of Florida

which are not governed by the Miami-

Dade County high wind regulations. More

information can be found on the Florida

Building Code website. Florida Product

Approval FL12680

High

Wind and

Hurricane

Greenheck is

leading the high

wind standard for

roof top fans and

ventilators. Forceful

winds and wind-

borne debris are

the cause of most hurricane damage. Hurricane

winds start at 75mph. At speeds over 150mph, wind

can exert a force of 75poundspersquarefoot of

pressure or over 900pounds on a fan. Forceful winds

are not the only problem, wind-borne debris can also

cause detrimental effects to objects and structures.

High winds and extreme forces are the cause of

most storm damage. By analyzing calculations,

computer simulations and actual testing—Greenheck

developed the High Wind Standard.

Temperature Options

Spark-Resistant Construction Options

The following AMCA Standards apply to fan

applications that may involve the handling of

potentially explosive or flammable particles,

fumes or vapors.

•AMCA Type A - All parts in contact with the

airstream are constructed of nonferrous material

(aluminum). Model SWB does not meet AMCA

Type A spark resistant construction because the

fan shaft is steel.

•AMCA Type B - The fan wheel is constructed

of nonferrous material (aluminum). A nonferrous

(aluminum) rub ring surrounds the fan shaft where

it passes through the fan housing. Available on all

SWB sizes with an aluminum wheel and rub ring.

•AMCA Type C - The inlet cone is constructed

of nonferrous material (aluminum). A nonferrous

(aluminum) rub ring surrounds the fan shaft where it

passes through the fan housing.

The constructions listed minimize the potential of

ferrous components making contact with each other

that may produce sparks. However, they do not

guarantee against the potential of producing sparks.

The installer must electrically ground all fan and

system components.

Testing

High temperature testing was conducted at

Greenheck’s Research and Development facility

with airstream temperatures in excess of 1000°F

(538°C). Temperatures were monitored at the

following critical locations throughout the tests:

bearings, bearing compartment, motor, motor

compartment, airstream and fan housing.

Operating Temperatures

Utility set fans are suitable for applications with

elevated temperature airstreams. Refer to the

chart at the right for operation temperature

guidelines and optional accessories.

High Temperature/Emergency Smoke Control

The SWB Series 200 sizes 212 to 224 and

Series 300 may be equipped for emergency

smoke removal applications by specifying a

high temperature option. The table below right

indicates the construction features included in

the high temperature options enabling exhaust

of heat and smoke at 500°F (260°C) for a

contact and provide snubbing for side loads. Springs

provide an additional 50% overload capacity and are

color coded to indicate load capacity.

Free-Standing Open

Spring Mounts -

Type 3, 1-inch Deflection

Free-standing spring isolators

are unhoused laterally stable

steel springs. They provide a

minimum horizontal stiffness

of 0.8 times the rated vertical

stiffness and provide an additional 50% overload

capacity. These isolators are equipped with a

top-mounted adjusting bolt and an acoustical

non-skid base. Springs are color coded to indicate

load capacity. Restrained Spring

Mounts -

Type 4A, 1-inch Deflection

Restrained spring isolators

consist of laterally stable,

free-standing springs

assembled into a steel

housing. These assemblies

are designed for vertical and horizontal motion

restraint. Restrained spring isolators can be used

for blocking during equipment installation and are

provided with leveling bolts. Springs provide 50%

indicate load capacity. Restrained spring mounts are

recommended for equipment subject to wind loading

or large torquing forces.

Equipment Supports

Models GESS and GESR equipment

supports are available for roof

mounting of utility fans up to size 36.

Equipment supports are available in

a number of lengths, widths, heights,

and can also be built for a pitched roof.

Vibration Isolators

Base-mounted neoprene or spring isolators are available to lessen mechanical vibration and assure quiet

operation. Free-standing, restrained and housed spring isolators are also available. Isolators are sized to

match the weight of each fan.

Mounting Rails

with Isolators

Isolation mounting

either rubber mount,

free-standing open

or restrained spring

isolators. The isolators

are mounted between

aluminum rails that

run the length of the

fan base. Isolation rails provide easy

installation on isolated systems,

and are ideal for

applications where

there is a large overhung load.

Mounting rails are available for fans up

to size 36.

Direct Mount - Type A

No base required. Isolators

are attached directly to

equipment. Direct isolation

can be used if equipment

is unitary and rigid without

the use of additional

support. If there is

any doubt whether or

not equipment can be

supported directly on isolators,

use rails, bases or consult the factory.

Engineering Data

Selection

The first consideration in any fan

selection is the amount of air to be

moved and the resistance to this air

movement. Air volume requirements are

established through specific codes or

accepted industry standards. Once the

air volume is known, system resistance

can be determined by summing up the

losses through the system components.

Duct layout, duct size, coils, filters,

dampers, and fan accessories all affect

system resistance. ASHRAE Guide and

Data Books and manufacturer’s data

on individual system components are

common sources of information available

to the system designer.

In most applications, several fans may

meet the required airflow and system

resistance conditions. An optimum fan

selection requires evaluation of alternative

fan types and fan sizes, as they relate

to initial cost, operating cost, available

space, and allowable sound levels. The

relative importance of these facts varies

with each system.

Two types of wheels are available:

1. Backward-inclined or airfoil wheels

turn at twice the speed of forward-

curved fans and feature:

• Higher operating efficiencies

• A non-overloading horsepower

curve which reaches a peak

near the middle of the normal

operation range

• Stronger wheel design allowing for

operation at higher static pressures

2. Forward-curved wheels typically

have lower performance capabilities

compared to the backward inclined

and contain:

• Overloading type wheel (meaning

that changes in performance

can result in significant brake

horsepower changes)

• Forward-curved wheels have lower

sound levels

Comprehensive air performance data for

these utility fans can be found in the fan

tables and fan curves section, starting on

page 15.

Effects of Installation on Performance

Fan ratings presented in the performance tables and curves

of this catalog are in accordance with AMCA Standard 210

“Laboratory Methods of Testing Fans for Aerodynamic

Performance Rating.” The AMCA test procedure utilizes an open

inlet and a straight outlet duct to assure maximum static regain.

Any installation with inlet or discharge configurations that deviate

from this standard may result in reduced fan performance.

Restricted or unstable flow at the fan inlet can cause pre rotation

of incoming air or uneven loading of the fan wheel yielding large

system losses and increased sound levels. Free discharge or

turbulent flow in the discharge ductwork will also result in

system effect losses.

The examples below show system layouts and inlet and

discharge configurations which can affect fan performance.

to meet restaurant and foodservice applications.

These fans are UL and cUL Listed for grease

removal and have been tested under elevated

temperature conditions.

Due to high temperatures and grease-laden

airstreams in commercial kitchen ventilation, system

designers must be aware of governing codes and

guidelines. The National Fire Protection Association

(NFPA) is the primary source used by many local

codes for commercial kitchen ventilation systems.

Local code authorities should be consulted before

proceeding with any kitchen ventilation project.

Installation must include a means for inspecting,

cleaning and servicing the exhaust fan.

Fans selected for grease removal must include a

weatherhood, access door and 1-inch (25 mm) drain

connection. For grease applications where the fan is

mounted indoors, the welded scroll option must be

selected. An outlet guard is strongly recommended

when the fan discharge is accessible. When an

outlet guard is not ordered with the fan, it must be

provided by the installer. An upblast discharge is

recommended. No dampers are to be used in

the system.

The fan discharge must be a minimum of 40 inches

(1016 mm) above the roof line and the exhaust

duct must be fully welded to a minimum distance

of 18 inches (457 mm) above the roof surface.
