Models H-G and H-GB
®
The Greenheck Models H-G (direct drive) and H-GB (belt drive) are centrifugal roof exhaust fans designed
specifically for high wind applications, such as hurricanes, tornadoes, and other high wind areas. The down
blast design is ideal for general clean air applications where air is discharged directly onto the roof surfaces.
Performance ranges up to 14,000 cfm (24,000 m3/hr) and up to 2.75 inches wg (700 Pa).
High winds can reach upwards of 150 mph in much of the world. At these elevated wind speeds roof top
equipment can see a force of over 750 pounds (340 kg). High winds and extreme forces are the cause of most
storm damage. In 2005, over $125 billion dollars in damage is linked to high winds and storms.

Government Certification
The H-G and H-GB Models are the only downblast aluminum fans in the
industry that have received a Miami-Dade NOA for high wind (150 mph)
and hurricane zones. (NOA # 07-0503.07).
State Licensed P.E. Calculations
The H-G and H-GB Models have been analyzed and stamped by a state licensed P.E.
to the ASCE 7-02 Standard which meets the IBC, Florida and Miami-Dade codes. Both
models have been proven to withstand winds in excess of 150 mph (61 psf).
Testing
Each of the Greenheck models have been subjected to extensive testing procedures. The H-G and
H-GB have been certified by an independent third party to the ASTM E330 Static Pressure Difference
Standard and TAS-202 static pressure difference Florida Building Code Test Protocol.
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 (150 mph) 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
150 mph winds through Finite Element Analysis utilizing CFD results.
Standard Construction Features
Roof Curb - High wind load fans are certified
with one of two Greenheck high wind roof curbs.
Standard 12 inch (305 mm) in height H-GPF curb has
a 5 inch (127 mm) flashing flange. Roof curbs ship
separate for field installation with attachment details
provided.
Internal Supports - Heavy gauge supports and
bracing are added for additional strength to
withstand a wind of 150 mph.
Wheel - An aluminum, backward-inclined, nonoverloading centrifugal wheel is utilized to generate
high efficiency and minimal sound. Wheel cones
are carefully matched to the venturi for maximum
efficiency. Each wheel is robotically welded and
statically and dynamically balanced for long life and
quiet operation.
Disconnect Switch - NEMA-1 switch is factory
mounted and wiring is provided from the motor as
standard (other switches are available). All wiring
and electrical components comply with the National
Electric Codes (NEC) and are either UL listed or
recognized.
Internal Conduit Chase - A large diameter conduit
for installing electrical wiring through the curb cap
into the motor compartment.
Fan Shaft - Is precisely sized, ground, and polished
so the first critical speed is at least 25% over the
maximum operating speed. Where the shaft makes
contact with bearings, close tolerances result in
longer bearing life.
Bearings - 100% factory tested and designed
specifically for air handling applications with a
minimum (L10) life in excess of 100,000 hours (L50
average life of 500,000 hours).
Motor Cooling - Cooling fins located on top of
fan wheel draw outside air through a large space
between the fan shroud and the motor cover directly
into the motor compartment. Positive motor cooling
with fresh air results in maximum motor life.
®
Motor - Carefully matched to the fan load and is
mounted out of airstream.
Motor Cover - Constructed of aluminum, machine
punched, and attached with stainless steel hardware
for easy removal and access to motor compartment
and drive assembly.
Drive Assembly - Belts, pulleys, and keys are
oversized 150% of driven horsepower. Machined
cast pulleys are adjustable for final system balancing.
Belts are static free and oil resistant.
Vibration Isolation - Vibration isolators support the
drive assembly and wheel for long life and quiet
operation.
Fan Shroud - One piece, heavy gauge aluminum
with a rolled bead for extra strength directs exhaust
air away from the mounting surface. The curb cap
and integral deep spun venturi are attached to the
windband and also constructed of aluminum to
prevent corrosion.
Nameplate - Permanent stamped aluminum plate for
exact model and serial number identification.
Galvanized Birdscreen - Galvanized rigid wire
protects the fan’s discharge from birds or small
objects.
Curb Cap - Curb cap (with integral deep spun venturi)
is constructed of aluminum and is one piece for a
weather-tight fit.
Lower Windband - Heavy gauge aluminum with
formed edges for added strength and provide
weather resistance.
Lifting Points - Select models have various lifting
points located on the drive frame and bearing plates.

Due to the varying airstreams encountered in commercial
ventilation, system designers must be aware of national,
state, and local codes and guidelines governing these
installations. Local code authorities should be consulted
before proceeding with any ventilation project.

In order to assure proper fan performance, caution must be exercised in fan placement and connection to the
ventilation system. Obstructions, transitions, poorly designed elbows, improperly selected dampers, etc., can
cause reduced performance, excessive noise, and increased mechanical stress. For performance to be as
published, the system must provide uniform and stable airflow into the fan.
