Severe Duty Options
High
Wind and
Hurricane
Greenheck is
leading the high
wind standard for
roof top fans and
ventilators. Forceful
winds and windborne 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.
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 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
Difference. NOA #09-0303.31
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 MiamiDade County high wind regulations. More
information can be found on the Florida
Building Code website. Florida Product

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.

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.

Mounting Options
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.
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.
Housed Spring Mounts
Type 4B, 1-inch Deflection
Housed spring isolators
consist of steel springs
assembled into a telescoping
housing with a top-mounted
adjusting bolt and an
acoustical non-skid base.
Housed spring isolators
include resilient inserts to prevent metal-to-metal
contact and provide snubbing for side loads. Springs
provide an additional 50% overload capacity and are
color coded to indicate load capacity.
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.
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.
Rubber Mounts -
Type 2, ¼-inch and
½-inch Deflection
Neoprene mountings
consist of a steel top plate
and base plate completely
embedded in colored (oilresistant) neoprene for easy
identification of capacity. Neoprene mountings are
furnished with a tapped hole in the center. This
enables the equipment to be bolted securely to
the rubber mount.
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%
overload capacity and are color coded or identified to
indicate load capacity. Restrained spring mounts are
recommended for equipment subject to wind loading
or large torquing forces.
Mounting Rails
with Isolators
Isolation mounting
rails are available with
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.

Engineering Data
Selection
Effects of Installation on Performance
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.
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.
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.
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.

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.
Upblast Discharge
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.
