Applications
High Wind and Hurricane
High Wind and Hurricane SFD, SFB and SWB Series 100 and 200
Greenheck is leading the High Wind Standard for rooftop fans and ventilators. Forceful
winds and wind-borne debris are the cause of most hurricane damage. Hurricane
winds start at 75 mph and can exert
a force of 75 pounds per square foot
of pressure—or over 900 pounds
on a fan and curb. 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, actual testing, and
other standards—Greenheck
Atlantic, Gulf and Pacific history of major hurricane tracks.
developed the High Wind Standard.
Protocols designed to protect against wind-borne debris and severe wind loads:
Structural
Performance Load
A static load that is 2 times the design load (180 pounds per square foot pressure) is applied both positive
and negative to simulate wind force loads in each direction. Structural Performance per Dade County
Protocol TAS-202 (ASTM E-330).
Large Missile
Impact Test
Large Missile Impact Testing is required when objects are located 30 feet or less from the ground.
The test is per Dade County Protocol TAS-201. The test unit is impacted three times with a piece of
lumber (2 in. x 4 in. x 6 ft.) weighing approximately nine pounds and traveling at 34 mph. This simulates
wind-borne debris striking the fan.
Greenheck has gone the extra mile and worked with Miami-Dade County to design a High Velocity
Miami-Dade County Hurricane Zone standard for rooftop fans. The SFD, SFB and SWB Series 100 and 200 models are
certified and approved by the Miami-Dade Building Code Compliance office and Texas Department of
Test Protocols
Insurance for use in hurricane zones.
Miami-Dade NOA
Numbers
The certifications can be viewed on the Miami-Dade County website under the NOA numbers listed below.
Models SFD, SFB and SWB Series 100 and 200 are the first upblast aluminum/steel fans in the industry
that have received a Miami-Dade NOA for high wind (150 mph) and hurricane zones.

Florida Building Code. The ASCE 7-05 Standard meets the IBC, Florida and Miami-Dade County codes.
Certified
Independent
Third-Party Testing
Each of the Greenheck models have been subjected to extensive testing procedures. 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 Protocols TAS-202 Static Pressure Difference
and TAS-201 Large Missile Impact. All tests are video taped for documentation of test method and results.
Computational
Fluid Dynamics
(CFD)
All Greenheck high wind models have been analyzed using Computational Fluid Dynamics (CFD). CFD is
computer software designed to simulate the flow of high speed winds over the surface of objects. The
software records the force profile exerted on the fan so it can be utilized in Finite Element Analysis (FEA).
Finite Element
Analysis (FEA)
Utilizing the results from CFD analysis Greenheck can accurately predict the stress, strain, and deflection
resulting from high wind loads. Greenheck high wind units have been proven to withstand high winds
through Finite Element Analysis utilizing CFD results.

Applications
Seismic and Spark-Resistance
Seismic - SFD, SFB
and SWB Series 100 and 200
With changes in building codes and standards more equipment is being
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.
IBC 2009 and 2012 are the latest versions 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
Dev
and
an construction of healthcare facilities to ensure
they
are safe and capable of providing services to
t
the
t public after a seismic event. OSHPD developed
their
own unique certification process to incorporate
t
the
t IBC and ASCE testing standards to ensure
equipment
remains operable after a seismic event.
e
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, it 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 model
SFD, SFB and SWB Series 100 and 200 fans to this type of testing ensures the fans will operate without
problems after a seismic event.
OSHPD Certification
No. 0113-10
The OSHPD certification numbers and supporting documents can be viewed on OSHPD’s
website and ensures that the fan has been subjected to and passed rigorous testing standards.
State Licensed
P.E. Calculations
When using the fans in applications which are not covered by California OSHPD standards Greenheck
models SFD, SFB and SWB Series 100 and 200 have been certified by a third-party engineering firm to
IBC 2009, 2012 and ASCE 7-05 standards. These engineers hold professional engineers (PE) licenses in
all 50 states so no matter where your job is located you are backed by a PE signature for your state.
Certified
Independent
Third-Party Testing
All Greenheck Seismically Certified Fan models have gone through extensive testing procedures.
Greenheck models SFD, SFB and SWB Series 100 and 200 have been certified to IBC 2009, 2012, ASCE
7-05 and California OSHPD standards through both engineering calculations and shake table testing of all
models by independent third-party engineering firms.

these AMCA Standards.
• AMCA Type A - All parts in contact with the airstream
are constructed of nonferrous material (aluminum).
Models SFB, SWD and SWB do 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 models
SWD and SWB Series 200 and 300.
• 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.

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 topmounted adjusting bolt and an acoustical non-skid
base. Springs are color coded to indicate load capacity.
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 (oil-resistant) 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.

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.

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

• Forward-curved wheels have lower

utility fans can be found in the fan tables and
fan curves section, starting on page 18.
