Standard Construction
Features
Superior
Hood Design
Greenheck’s interlocking rib design combines four material thicknesses with I-beam design principles producing
a hood far superior in strength to conventional designs (an important feature in high snow or wind load regions).
Formed channels adjacent to the ribs provide water drainage to ensure weather tightness.
Hoods are available in galvanized steel, painted steel, or aluminum construction. Hood support angles are
heavy-gauge galvanized steel. Hood panels and supporting frame members are shipped loose to the field.
Construction Features
• Fan hoods and bases are constructed of
galvanized, aluminum, steel, or painted steel as
specified. Hood panels are arched and precision
roll-formed for strength and weather tightness.
Hoods are field bolted to heavy-gauge support
angles. Bases include prepunched mounting holes.
• Propellers are constructed with fabricated steel,
fabricated aluminum or cast aluminum blades and
hubs. All propellers are statically and dynamically
balanced. Reversing fan propellers are designed
to produce a high level of efficiency over a broad
selection range. Tapered airfoil blades are cast of
aluminum alloy. The reversible propeller is designed
to move air in both the exhaust or supply modes.
block bearings are 100% factory tested and are
designed specifically for air handling applications
with a minimum (L10) life in excess of 100,000 hours
(L50 average life of 500,000 hours) at maximum
cataloged operating speeds.
• Fan shafts are precisely ground and polished
steel sized so the first critical speed is at least
25% over the maximum operating speed. Close
tolerances where the shaft makes contact with the
bearing result in longer bearing life.
• Heavy-duty ball bearing motors are carefully
matched to the fan load.
• Drives shall be sized for a minimum of 150% of
driven horsepower. Pulleys shall be fully machined
cast iron, keyed and securely attached to propeller
and motor shafts. Motor sheavesshall be
adjustable for final system balancing. Belts are
static-free and oil resistant.
• Drive frames (belt drive fans) or motor support
frames (direct drive fans) and panel assemblies are
constructed of heavy-gauge steel.
• Fan panels are constructed of heavy-gauge steel
with a deep-formed inlet venturi. Reversible fans
are constructed of heavy-gauge steel with a double
venturi for efficient airflow.

Features
Access and Service
Periodic maintenance requires accessibility to fan
components such as motors, belts, pulleys and
propellers located under the hood. Greenheck’s
hooded roof propeller fan design incorporates many
service-friendly features which reduce maintenance
time and promotes proper servicing.
These features include:
• Hinged Hood - Sizes 36 and smaller can be
hinged by removing two of the four hood fasteners.
The hood may then be laid over on the roof deck
while servicing.
• Removable Hood - Sizes 36 and larger allow for
complete removal of the hood by removing the four
hood fasteners.
• Removable Birdscreens - Inspection of fan
components is quick and easy by removing the
quick-release
birdscreen sections
on either end of the
unit while leaving
the hood in place.
Birdscreens are
constructed of 1/2
inch galvanized
steel mesh. Filters
are optional. Access for sizes 42 and larger is from
underneath the hood by removing the birdscreen
or filters.
Easy Field Assembly of Hoods
Fans ship in kitted sections—assembled fan module,
hoods and supporting structural components – for
easy assembly. Hood assembly requires no special
tools or training. Each fan comes with complete
illustrated assembly and installation instructions.
Reversible Fans
Ventilation requirements are often subject to daily
or seasonal changes in temperature. Greenheck’s
reversible fans (models RPDR, RPBR, RPDRF, and
RPBRF) are designed for non-ducted systems or
those with short duct runs and offers the ability to
either exhaust or supply air on demand to maintain
comfortable working conditions. By exhausting
excess heat or supplying fresh outside air, the
reversing fan saves cooling costs. Fewer fans
required on the job means lower initial costs and
lower installation costs with fewer roof penetrations.
Filtered Supply
Filtered supply
fans (models RBF,
RBCF, RPDRF, and
RPBRF) with a 2-inch
aluminum mesh,
washable filters
are available for
applications where
contaminants must be removed from supply air.
Basic hood and fan construction is similar to the
non-filtered models.
Filter removal for cleaning or replacement can be
easily done by opening the hood and sliding the filters
out of the open end racks. In fan sizes 36 and larger,
access panels on either end of the hood are provided
to allow filter removal without raising the hood.
One Fan — Two Functions
EXHAUST SUPPLY
Evacuates excess
heat to reduce
cooling costs.
Outside air can
be supplied when
temperatures are
cooler (as at night) to
reduce cooling costs.

Options and Accessories
Tall Base –
Tall bases are
recommended
for installations
that include a
gravity damper
or a motorized
damper and
greatly simplifies installation and servicing. The
damper components are factory assembled as part
of the tall base and shipped as a single unit reducing
field assembly time and costs. Inspection, service
and cleaning of the damper, actuator and linkages are
made easy with an access door including two cam
latches with plated steel handles and a slide-out rack.
Tall bases provide the necessary minimum spacing
between the propeller and the damper. The tall base
increases the standard height to provide additional
weather tightness from rain and snow intake due to
the elevated hood. There is ample space within the tall
base for ease of initial electrical wiring.
Tie Down Feature – In locations where strong winds
may occur, cable tie-downs are recommended to
secure fans to the roof structure to prevent damage to
the hood. Cables are by others.
Roof Curbs – Prefabricated roof curbs are available
to reduce installation time and costs by ensuring
compatibility between the fan, the curb and the roof
opening. All curbs are available in steel or aluminum
construction and are lined with fiberglass insulation to
prevent condensation and reduce sound levels. See
Greenheck’s roof curb catalog for complete details.
Curb Cap Stripping – Rubber curb cap stripping
attached to the underside of the curb cap is available
to provide a seal between the fan and the roof curb.
Insect Screen Base – Insect screen bases are
available for applications where the building must
be insect free, as in food processing operations.
Construction is steel or aluminum with a fine mesh
aluminum screen. The base includes an access door
to allow easy removal of the screen section
for cleaning and periodic inspection.
Access Door
Insect
Screen
Base
Four galvanized steel brackets are provided as
standard on all hooded propeller roof fans as cable
attachment tie-down points at the ends of each hood
support rail.
Safety Guards – Safety
guards mounted to the fan
inlet are recommended to
protect the fan and nearby
personnel in non-ducted
applications. The installer
should provide a safety
guard if not ordered with
the fan.
Aluminum Housings – Aluminum exterior
construction is available for the hood sections and
bases of all models. Aluminum housings can also be
coated with decorative or protective finishes.
Hood Insulation – Fiberglass insulation attached to
the underside of the hood to minimize condensation
and reduce sound is available in either 1/2-inch or
1-inch thicknesses.
Special Coatings – Special coatings are available
for decorative or protective purposes. Decorative
coatings are applied to exterior surfaces of the hood
and base. Protective coatings are applied to the
entire unit. Coatings include baked polyesters,
enamels, epoxies, phenolics, vinyl, and others.
Protection from corrosive atmospheres requires
individual consideration.
Extended Lubrication Lines – Extended lubrication
lines allow for fan shaft bearing lubrication without
disassembling the unit or removing the hood.
Lubrication lines with grease fittings extend from the
fan shaft bearings to the exterior of the fan base.
Lifting Lugs – Four heavy-gauge steel brackets are
available to provide lifting points when raising the fan
to the roof.

Options and Accessories
Disconnect Switches – Toggle type and heavy-
duty disconnect switches are available for positive
electrical shut-off and safety in servicing fans. The
following switches are available to meet individual
electrical requirements and can be factory mounted
or shipped loose for field mounting. Wiring from the
motor to the disconnect box is provided with factorymounted disconnect switches.
• NEMA-1 for general purpose
• NEMA-3R for rain resistance
• NEMA-4 for watertight
• NEMA-3R and NEMA-4
for heavy-duty
• NEMA-7 and NEMA-9 for Class 1 and Class 2
hazardous locations and explosion
resistant applications.
UL/cUL 705 – All belt and selected direct drive fans
with totally enclosed, TE standard efficiency, singlespeed motors are available with the UL/cUL 705
listing for electrical.
1-Point Wiring – Available when the following items
are selected: a tall base, common voltages on the
motor and the actuator, and disconnect mounted and
wired. The wires are pulled from the motor and the
actuator on the damper to the disconnect box. (Hardwiring of the components to the disconnect switch is
by others.)

Exception: When a specific voltage is not available
on the actuator, Greenheck will provide a hard-wired
transformer to the actuator. Greenheck will then pull
the wires from the transformer to the disconnect box.
Wiring Pigtail – Available only in conjunction with
factory mounted disconnect switches. Liquid-Tite
wiring extends beyond the fan and allows direct hookup to the power supply. This eliminates field wiring
within the fan. Internal or external power supply can
be specified.
End Switches – Factory-mounted end switches
allow the damper to open completely before the fan
is energized. This reduces back pressure and brake
horsepower load on the fan motor at start-up.
Dampers – Backdraft dampers (also called gravity
dampers) allow airflow in one direction and prevent
reverse airflow for use in the exhaust or intake HVAC
systems. Backdraft dampers can either be operated
by gravity (where pressure or velocity opens and
closes the damper) or motorized to open and close
when required. When the damper is not factory-
installed in a tall base, the damper is to be installed
under the roof curb to provide adequate distance from
the fan.

changes in volatile organic compounds (VOCs). VOCs
are gasses that are emitted from humans, building
materials, perfumes, foods, and furniture off-gassing.
The range is 0-2000 CO2 PPM equivalent.
For reversible models, RPDRF and RPBRF, with 2-inch
washable aluminum filters, use the filter performance
graph above to determine the static pressure drop
added by the filters. The filter loss is included in the
performance data and no calculation will need to be
determined for the RBF and RBCF models.
The airflow (CFM) and the desired fan size must be
known to determine the pressure drop added by
the filters.
Example: Size 42-inch RPDRF for 20,000 cfm at
0.125 in. wg.
• On the graph above, locate the 20,000 cfm line and
read upward to its intersection with the 42-inch
curve. Read left to the static pressure (in. wg), in
this case 0.14 in. wg.
• Add 0.14 in. wg from the filter chart to the original
0.125 in. wg for a total of 0.265 in. wg.
• Using the RPDR-42 performance table on page 17,
20,000 cfm at 0.265 in. wg falls into the 5 hp range
at 1025 frpm. In a supply mode you do not want to
exceed 600 frpm to prevent intake of moisture.

Reversible Fan Control Center
Model ES-CC control center is designed specifically
for Greenheck’s reversible fan models. Its function
is the selection and control of the exhaust/supply
operation from a convenient remote location.
The ease of installation and operation of the control
center makes it more economical than the design and
construction of a custom control system in the field.
(Wiring between fan and control center is by others).
Controls are housed in a NEMA-1 cabinet constructed
of heavy-gauge steel and coated with Greenheck’s
Permatector
switch is provided to help prevent electrical shock
when the door is opened. Magnetic starters are
included as part of the control center as standard.
Controls
• Mode Selector – The mode selector switch is used
to engage the desired fan function. A time delay is
provided to allow the fan to come to a complete
stop before reversing.
• Options – An indicator light mounted on the control
panel door is available to indicate power to the fan.
The model number system is designed to completely identify the fan. The correct code letters must be specified
to designate direct drive with exhaust or supply air configuration. The remainder of the model number is
determined by the size and performance selected from the following pages.
