Standard Construction Features
A backward-inclined, non-overloading centrifugal wheel is utilized to generate high-
Wheel 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 NEMA-1 switch is factory-mounted and wiring is provided from the motor as standard
Switch (other switches are available).All wiring and electrical components comply with the
National Electrical Code®(NEC) and are either UL Listed or Recognized.
Precisely sized, ground and polished, so the first critical speed is at least 25% over
® Fan Shaft the maximum operating speed. Where the shaft makes contact with bearings,tight
tolerances result in longer bearing life.
0 Bearings 100% factory tested and designed specifically for air handling applications with a
minimum L10 life in excess of 100,000 hours(L50 life of 500,000 hours).
Motor Carefully matched to the fan load and mounted out of the airstream.
Motor Cover Constructed of aluminum and attached with fasteners for easy removal and access to
motor compartment and drive assembly.
Cooling fins located on top of the fan wheel draw outside air through a large space
® Motor Cooling between the fan shroud and the motor cover directly into the motor compartment.
Positive motor cooling with fresh air results in maximum motor life.
0 Lifting Points Various lifting points are located on the drive frame and bearing plate(on select sizes).
�J d True Vibration Vibration isolators, with no metal-to-metal contact, support the drive assembly and
Isolation wheel for long life and quiet operation.
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.
Lower Windband Heavy-gauge aluminum with formed edges for added strength and provides
weather resistance.
Curb cap(with integral deep spun venturi)is constructed of aluminum and is one-piece for

a weather-tight fit.
Not Internal Conduit A large diameter conduit for installing electrical wiring through the curb cap into the
Shown Chase motor compartment.
® Nameplate Permanent embossed aluminum plate for exact model and serial number identification.
Galvanized Rigid wire protects the fan discharge from birds and small objects.
Birdscreen
® Fan Shroud One-piece, heavy-gauge aluminum with a rolled bead for extra strength directs exhaust
air downward.
Mounting Holes Curb cap has prepunched mounting holes to ensure correct attachment to the roof.
High Wind Construction Features
Internal Supports Heavy-gauge supports and bracing are added for additional strength to withstand
a load of 75 psf.
Reinforced High wind fans include additional reinforcement for maximum strength.
Windband
Roof Curb High wind-load fans are certified for use with Greenheck model GPFHL, GPFHD, GPF or
(page 11) equivalent in high wind applications. Roof curbs ship separate for field installation with
attachment details provided.

Models G and GB exhaust fans meet the needs of
general clean air applications. Tests were conducted
to ensure safe, rugged and reliable fans. o00
Due to the varying types of airstreams encountered
in commercial ventilation, system designers must
be aware of national, state, and local codes and
guidelines governing these installations. Consult Figure 1

Fan Inlet Connections
To ensure proper fan performance, exercise caution
in fan placement and connection to the ventilation Good
system. Obstructions, transitions, poorly designed
elbows, improperly selected dampers, etc., can Good
cause reduced performance, excessive noise, and
increased mechanical stress. For performance to be
