Belt Drive Fan Selection
Three propeller drive frame construction levels are available with either a
L or H type propeller. The application requirements for sound and static
pressure determine propeller type. Propellers are available in fabricated
steel, fabricated aluminum or cast aluminum.
• Propellers typically run at lower
RPMs and generate low sound
levels.
• The best selection for sound
critical applications or
applications that require the
best combination of both air and
sound performance.
• Typically used when the static
pressure is 0.5 in. wg (125 Pa)
or less.
H Type Propeller:
• Straight, moderately pitched
blade.

Disconnect Switches
Coatings
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 factory mounted disconnect switches.
A variety of special coatings ranging from enamels
to phenolics are available for decorative or protective
purposes. When a special coating is selected for the
fan, all accompanying accessory items are also coated
unless specified. Consult your local representative for
more details.
• NEMA-1 - General purpose
Welded and Painted Fan Construction
• NEMA-3R - Rainproof
For applications where extra heavy construction
is required, welded steel construction is available.
With this option, all stationary connections which
are normally bolted, are welded and coated with an
industrial grade paint. This option applies to belt drive
level 3 fans and direct drive level 2 and 3 fans only.
• NEMA-4 - Watertight
• NEMA-3R & NEMA-4 Heavy Duty
• NEMA-7 & 9 - for Class 1 and
Class 2 hazardous locations.
NEMA-3R
and NEMA-1
UL/cUL 705
All belt and selected direct drive fans with TE standard
efficiency, single-speed motors are available with the
UL 705 listing for electrical.
Extended Wiring Pigtail
Available only in conjunction with factory mounted
disconnect switches, liquid tight wiring pigtails allow
direct hook-up to the power supply which eliminates
field wiring at 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 will
reduce the back pressure and brake horsepower load
on the fan motor at startup. (Field supplied motor
starter with a relay is required to complete the wiring on
a system using an end switch.)
One-Point Wiring
Available when the following items are selected:
• Common voltages on the motor and the actuator
• Disconnect mounted and wired
• Wall housing
The wires are pulled from the motor and the actuator on
the damper to the disconnect box. (Hard wiring 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.
(see below)
Greenheck MSAC Motor Starters
Can be used to coordinate dampers, end switches and
motor starting. They protect the motor, offer control
options, and provide Lockout/Tag out features as well.

Weatherhood
Weatherhoods shield wall openings and dampers from
rain and snow. Weatherhoods are shipped unassembled
in kit form for field assembly. Construction is of galvanized
steel with wire mesh birdscreen. Mounting flanges have
prepunched mounting holes. 45° turn down is for exhaust
and 90° turn down is for exhaust and supply. Options
include aluminum construction, insect screen and painted
finish. The weatherhood cannot be used with the damper
guard option.
Damper Guard
Damper guards meet the OSHA requirements to completely
enclose the damper or wall openings on the discharge side
of the fan. They are constructed of expanded galvanized
steel screen in galvanized steel frames. Mounting flanges
have prepunched mounting holes. Options include aluminum
construction and painted finish. The damper guard cannot
be used with the weatherhood option.
Dampers
Used alone or in conjunction with the wall housing or wall
collar, a complete line of dampers are available for exhaust
or supply configurations.

spacer
For exhaust fans, there is a minimum dimension
(M) which must be maintained between the
propeller and damper, or guard to achieve
optimum performance (failure to meet this minimum
dimension will result in loss of fan performance,
increased noise and shortened fan and damper
life). There is also a minimum required wall opening
dimension (W.O.) to allow the venturi to fit into the
wall opening.

Louver Mounting
Where an exterior louvered appearance is desired, a variety of louvers
can be used in conjunction with the wall housing or wall collar as shown.
However, since louver free area is less than half of the wall opening,
pressure drop across the louver must be considered when specifying the
fan. The graph below shows louver pressure drop for Greenheck model
EDJ-430 based on CFM and fan size.
For additional louver information visit www.greenheck.com or refer to the

Wall Housing Mounting
Wall Collar Mounting
Wall housings are the
safest, most efficient and
sturdy platform for mounting
sidewall propeller fans and
their optional accessories.
Wall housings allow for a
wide range of mounting
arrangements to meet
specific applications. It is
constructed of galvanized
steel (painted steel optional) with heavy gauge
mounting flanges and prepunched mounting holes.
Protective guards of welded steel wire completely
protect the drive side of the wall housing. Guards are
coated with Permatector™, a thermal setting polyester
urethane. Other paint finishes are also available.
Wall housing guards that meet OSHA requirements
are also available.
Wall collars offer an alternate
method for mounting sidewall
propeller fans and the optional
accessories shown here.
Standard construction is of
galvanized steel (painted
steel is optional) with heavy
gauge mounting flanges and
prepunched mounting holes.
Note: Wall collar, fan, damper and guards
ship completely factory assembled
except when ordered as a kit.
Weatherhood ships loose.
The wall housing is designed to reduce installation time
and provide maximum installation flexibility. Attached
accessories such as backdraft dampers, guards
and weatherhoods may mount to either end. As a
result a wide variety of configurations are available to
accommodate the needs of the system designer.
Note: Wall collar, fan, damper and guards
ship completely factory assembled
except when ordered as a kit.
Weatherhood ships loose.
Water Ingress and Mitigation
Fans installed to supply air to a building carry the
inherent risk of supplying moisture to the building as
well. Rain, snow, driving wind, and cold temperature
frosting can all contribute to the possibility of unwanted
moisture entering the building.
The amount of water captured is dependent on air
velocity, water droplet size, length of event, wind
strength and wind direction. Because of these variables
some degree of water entrainment can occur. Caution
should be exercised when supplying air with a sidewall
propeller fan.
Wall housing or wall collar should be tipped slightly to
the outside for water drainage.
• Weatherhoods and louvers are recommended to
reduce the likelihood of water entering a building
through the fan opening.
• Installing the fan with a slight slope toward the outside
(1/8 inch per foot or more) will minimize water ingress
to the building.
• Air velocities below 500 ft/min reduce the risk of rain
ingress; however snow can be captured at much
lower rates.
• Installation orientation consideration - mounting a fan
on west or south side of a building increases potential
for driving rain/moisture. Consider the north or east
side for supply air fan mounting.
• Consider mounting under an eave with a rain gutter if
fan will be mounted near the roofline.
12
Selection Basics
The first consideration in any fan selection is the
amount of air to be moved and the resistance to this air
movement. With specific performance and application
criteria in mind, propeller fan selections typically require
decisions based on the following criteria.
Belt Drive vs. Direct Drive
Belt drive fans offer the ability to adjust fan speed for
system balancing if necessary. They also offer more
flexibility in speeds and motor selections. In a cost
comparison, belt drive fans are typically less costly
than comparable size direct drive fans with low
speed motors.
Direct drive fans are often preferred for jobs where
maintenance access is difficult. Maintenance costs are
generally lower with direct drive fans, since there are no
belts or bearings to replace and no pulleys to adjust.
Larger Fans vs. Smaller Fans
In most applications, several fans may meet the
specified airflow and pressure requirements. Just as
larger fans tend to turn slower and generate less sound,
they also tend to have higher initial costs but lower
operating costs. Smaller fans, with their higher speeds,
have more stable performance curves, lower initial
costs, higher sound levels, and higher
operating costs.
Low Sound vs. High Static Pressure
Fans selected for high static pressures run at higher
speeds and produce higher tip speeds, resulting
in higher sound levels. Conversely, in low pressure
applications, fans generally run at lower speed
producing lower sound levels and are recommended
for sound sensitive applications.
How Accessories Affect Static Pressure
All accessory losses must be accounted for when
calculating static pressure load. In most cases
dampers, guards and weatherhoods actually add
very little to the total system pressure. This means
that propeller fans used in conjunction with common
accessories can typically be specified with low pressure
capabilities below .375 in. wg (93 Pa). However, in
cases where airflow velocities exceed 1,500 ft/min
(7.6 m/s) through the damper or where filters are
used, static pressure loss may be significant. For
more specific information on pressure losses due to
accessories, refer to pages 10 and 11.
Motor Service Factor
Motors for sidewall propeller fans are cooled by the
airstream. With an uninterrupted flow of cooling air,
motors may be operated in their service factor range
(up to 20% above the motor’s nameplate horsepower)
without damage due to overheating. Lesser overloads
are recommended for applications using totally
enclosed or explosion resistant motors.
Belt drive performance tables in this catalog
show two speed selections for each propeller
type (L or H) at a given motor hp. The first selection is
at 1.0 service factor. The second speed selection is at
1.2 service factor. Direct drive performance tables show
Bhp levels with service factors ranging up to 1.2. When
a selection at 1.2 service factor is not desirable for the
application, specify the next higher motor horsepower.
Propeller Fan Rotation Guide
Propeller blade should cup and throw the air when
rotating in the correct direction as shown below.
13
Mounting Options
Flush Exterior
Sidewall propeller housings can be oriented in eight
horizontal and eight vertical configurations. The two
main considerations for determining which orientation
the project requires are:
1. Will the fan and housing be placed inside the building
or outside of the building?
2. How will the motor and drives be most easily
accessed, from inside of the building or from outside
of the building?

Mounting Options
Flush Interior
Flush Interior: The fan and housing will be outside the
building and the end of the housing will be flush with the
interior wall.
Flush Exterior: The fan and housing will be inside the
building and the end of the housing will be flush with the
exterior wall.
Motor Access: The motor and drives can be placed
on either side of the propeller for access to grease
bearings, check or change belts and inspect the motor/
wiring connections. Failure to assess the best access
point can place maintenance personnel in extreme
danger if they must reach through the propeller.

WD-320, which has the
prepunched mounting
flange located on the
outlet end of the damper
for a flush exterior
appearance.
For applications where
the mounting flange is
required on the inlet end
of the damper (so that
the damper projects to
the exterior), the model
WD-300 is available.

Dampers
Volume Control / Heavy Duty
Volume control dampers are available for exhaust
or supply configurations and may be used alone or
in conjunction with the wall housing or wall collar.
Constructed with heavy galvanized steel frames and
blades, model VCD dampers are designed to handle
higher air volumes than the standard backdraft
damper. Dampers are available in standard leakage
(VCD-20), low leakage (VCD-23) and insulated low
leakage (VCD-34) configurations. Actuators are
available in 24, 120, 208, 230 or 460 volts. Actuators
for 50 cycle voltages are also available.

Vari-Green® Options
Vari-Green® Motors
Features
Model SE1
Greenheck’s electronically commutated (EC)
Vari-Green® (VG) motor combines motor
technology, controllability and energy-efficiency
into one single low maintenance unit. When combined
with Greenheck’s SE1 fans, the VG motor offers variable
volume capability and energy-efficiency without using a
variable frequency drive (VFD). The Vari-Green motor
has built in overload and temperature protections,
so it does not require a stand-alone motor starter
for protection.
1. Dial on Motor Control - A potentiometer (dial on
motor control) is mounted on the motor for easy
speed adjustment for system balance. Simply turn
the dial; there are no belts and pulleys to adjust.
2. Control Wire Inputs - the motor accepts a
0-10 VDC signal from Building Automated
Systems, Vari-Green controls or other
controls to adjust motor speed.

Vari-Green® Controls
Transformer - 24V power from the existing line voltage
at the fan to the Vari-Green motor and controls. Dual
voltage primary (120/240V) transformer provided with
the fan.
Remote Dial - Allows for remote, manual airflow
adjustments. Wall plate with dial may be mounted in a
standard 2x4 inch electrical junction box.
Two Speed Control with Integral Transformer
Control allows motor RPM to be set at two
independent speeds (high or low). Meets minimum
airflow requirements with the ability to bump up
to high speed in an emergency or meet maximum
airflow requirements, or reset down to low for energy
conservation.
Constant Pressure Control - Control Vari-Green motor
via static (variable volume) or velocity (constant CFM)
pressure on the inlet or outlet side of the fan. Optional,
duct or room probes for use in:
• Multifamily structures - Apartments, condos, hotels;
dryers, residential kitchens and bathrooms.
• Institutional facilities - Schools, prisons, multistory
office buildings; bathrooms.
22
Air Quality - VOC - Control a Vari-Green motor via
changes in volatile organic compounds (VOC’s). VOC’s
are gasses that are emitted from humans, building
materials, perfumes, foods, and furniture off-gassing.
Range is 0-2000 CO2 PPM equivalent.
• Institutional facilities - Schools, court houses,
hospitals; bathrooms, waiting rooms, cafeterias.
• Commercial buildings - Office spaces, conference
rooms, bathrooms, break rooms.

Vari-Green® Motor Options
Benefits
Operates on AC power that’s converted to DC—
providing a more efficient motor operation as compared
to an AC operation.
• Maintenance costs are reduced as there are no belts
or bearings to replace and no pulleys to adjust.
• Direct drive fans are often preferred where
maintenance access is difficult.
• The motor can attain up to 85% efficiency and reduce
energy consumption.
• Provides a solution for demand controlled ventilation
applications.
• Watt savings of 30-70% depending on rpm.
Vari-Green Advantages
Note: As motor speed is turned down, efficiency stays high
as compared to an AC motor that decreases dramatically.
• Initial cost is less than a belt drive/motor starter
combination.
• Operates cooler than a standard AC motor at lower
RPMs. A cooler motor has longer motor life and
reduces energy consumption.
• Lower operating cost
• 80% usable RPM turndown as low as 300 rpm.
• Easy RPM adjustment
• No maintenance, no belts, pulleys or bearings
• SEI fans with Vari-Green motors can provide all the
CFM and static pressure ranges of a comparable
belt drive.

Using The Performance Table
Shown below is a portion of a typical performance table used in this catalog. Performance data shown
offers the best selections for each propeller type (“L” or “H”) relative to sound, RPM and static pressure.
Consider “L” type propellers first for most applications.
Many sidewall applications can be met with the “L” type propeller. When using the performance
tables, look first at the “L” selections, because they offer the lowest speed and sound levels.

Performance certified is for Model SB for installation type A: free inlet, free outlet. Power rating (Bhp) does not include transmission losses. Performance ratings do not include
the effects of appurtenances (accessories). The sound ratings shown are loudness values in fan sones at 5 ft (1.5 m) in a hemispherical free field calculated per AMCA Standard 301.
Values are for installation type A: free inlet hemispherical sone levels. *Sones shown apply to the highest cataloged CFM in black type at each fan RPM. For selections at other CFM and static
pressure points, refer to CAPS, the Computer Aided Product Selection Program.

Performance certified is for Model SB for installation type A: free inlet, free outlet. Power rating (Bhp) does not include transmission losses. Performance ratings do not include
the effects of appurtenances (accessories). The sound ratings shown are loudness values in fan sones at 5 ft (1.5 m) in a hemispherical free field calculated per AMCA Standard 301.
Values are for installation type A: free inlet hemispherical sone levels. *Sones shown apply to the highest cataloged CFM in black type at each fan RPM. For selections at other CFM and static
pressure points, refer to CAPS, the Computer Aided Product Selection Program.

Performance certified is for Model SBC for installation type A: free inlet, free outlet. Power rating (Bhp) does not include transmission losses. Performance ratings do not include
the effects of appurtenances (accessories). The sound ratings shown are loudness values in fan sones at 5 ft (1.5 m) in a hemispherical free field calculated per AMCA Standard 301.
Values are for installation type A: free inlet hemispherical sone levels.*Sones shown apply to the highest cataloged CFM in black type at each fan RPM. For selections at other CFM and static
pressure points, refer to CAPS, the Computer Aided Product Selection Program..
