Sidewall Propeller Fans
Greenheck’s sidewall propeller fan line is the ideal choice for factory and
warehouse applications where high volumes of air and low pressures are
required. From general ventilation to industrial duty, the range of construction
and performance capabilities offered represent the most comprehensive sidewall
propeller fan line in the industry.
Performance spans the range between 300 to 87,000 cfm (510 to 147,814 m3/hr)
with static pressures to 1.25 in. wg (249 Pa). Fan sizes range from 8 to 54 inches
(203 to 1372 mm) for direct drive and 20 to 72 inches (508 to 1829 mm) for belt
drive. Regardless of fan size, performance or duty level, all Greenheck sidewall
propeller fans are built to perform with the same high standards of reliability and
durability. All models are available in exhaust or supply arrangements.
Models SE1, SS1, SE2, SS2, SCE3, SCS3, SCR3, SBE-1, SBS-1, SBE-2, SBS-2, SBE-3, SBS-3, SBCE, SBCS, and SBCR.
Filtered Supply
Filtered supply wall housings are available in seven sizes for fans ranging
from size 24 to 54 inches (610 to 1372 mm). They are designed with
the draw-thru concept to achieve the highest filter and fan efficiencies.
Permanent 2 inch (51 mm) washable filters are accessed through a bolted
panel and can be easily removed for cleaning.
General Safety Information
Only qualified personnel should install this fan.
Personnel should have a clear understanding of
these instructions and should be aware of general
safety precautions. Improper installation can result
in electric shock, possible injury due to coming in
contact with moving parts, as well as other potential
hazards. Other considerations may be required
if high winds or seismic activity are present. If
more information is needed, contact a licensed
professional engineer before moving forward.
the National Fire Protection Agency (NFPA),
where applicable. Follow the Canadian Electric
Code (CEC) in Canada.
2. The rotation of the propeller is critical. It must
be free to rotate without striking or rubbing any
stationary objects.
3. Motor must be securely and adequately
grounded.
4. Do not spin fan propeller faster than max
cataloged fan RPM. Adjustments to fan speed
significantly effects motor load. If the fan RPM is
changed, the motor current should be checked
to make sure it is not exceeding the motor
nameplate amps.
DANGER
Always disconnect, lock and tag power source before
installing or servicing. Failure to disconnect power source
can result in fire, shock or serious injury.
5. Do not allow the power cable to kink or come
in contact with oil, grease, hot surfaces,
or chemicals. Replace cord immediately if
damaged.
CAUTION
When servicing the fan, motor may be hot enough to
cause pain or injury. Allow motor to cool before servicing.
CAUTION
Precaution should be taken in explosive atmospheres.
6. Verify that the power source is compatible with
the equipment.
7. Never open access doors to a duct while the fan
is running.
1. Follow all local electrical and safety codes, as
well as the National Electrical Code (NEC) and

Fans mounted to the wall require a different wall
opening (W.O.) size than those mounted in collars or
wall housings. Propeller-to-damper distance (M) is
important to reduce turbulence and damper flutter
which may lead to premature damper failure.
Pre-Installation Checks
• Check chart below for correct wall opening
dimensions.
• Check motor voltage and amperage rating for
compatibility with electrical supply. Supply wiring
must be properly fused and conform to local and
national codes.
Figure 1 and 2 show the wall opening (W.O.) required
for installations with either a wall housing or collar.
Figure 3 shows the recommended wall opening
(W.O.) and the minimum distance (M) suggested
between the fan and damper for direct to wall
installations.
Figure 4 shows the dimensions and wall opening
(W.O.) required for installations with a filtered supply
wall housing.
• Motor load amperage must be checked and
compared to nameplate rating to avoid serious
damage to motor when speed is increased.
Wall Opening Requirements
Wall opening size and propeller-to-damper distance
are two important dimensions for fan installation.

source can result in fire, shock or serious injury.
Typical Installation
Move fan to the desired location and determine the
method by which the fan is to be mounted as shown
in Figures 1-4 shown on page 3. Optional wall mount
housings (Figure 1) and wall mount collars (Figure
2) provide a convenient means of mounting sidewall
propeller fans while maintaining the proper distance
between propeller and damper.
Step 3 Install Weatherhood
Optional 90º
Weatherhood
Attach the fan by inserting a suitable fastener
through each of the prepunched mounting holes in
the fan panel. Care should be taken not to bend or
distort the fan panel or drive components during
installation.

number of turns open. Any increase in fan speed
represents a substantial increase in horsepower
required from the motor. Always check motor load
amperage and compare to nameplate rating when
changing fan speed.
Bearings (For belt drive fans only)
Bearings are the most critical moving part of the
fan and should be inspected at periodic intervals.
Locking collars and setscrews, in addition to
fasteners attaching the bearings to the bearing
plate, must be checked for tightness. In a clean
environment and temperatures above 32ºF (0ºC)
and below 200ºF (93ºC), fan shaft bearings with
grease fittings should be lubricated semi-annually
using a high-quality lithium based grease. If unusual
environmental conditions exist, temperatures below
32ºF (0ºC) and above 200ºF (93ºC), moisture or
contaminants, more frequent lubrication is required.
Routine Maintenance
Once the fan has been put into operation, a periodic
maintenance program should be set up to preserve
the reliability and performance of the fan. Items to
be included in this program are: Belts, Bearings,
Fasteners and Setscrews, Lubrication, and Removal
of Dust and Dirt.
WARNING
With the unit running, add grease very slowly with
a manual grease gun until a slight bead of grease
forms at the seal. Be careful not to unseat the seal
by over lubricating or using excessive pressure.
Bearings without grease fittings are lubricated for
life.
Always disconnect, lock and tag power source before
installing or servicing. Failure to disconnect power
source can result in fire, shock or serious injury.
Belts
Fasteners and Setscrews
Any fan vibration has a tendency to loosen
Premature belt failures are frequently caused by
improper belt tension (either too tight or too loose) or
misaligned pulleys. The proper tension for operating
a V-belt is the lowest tension at which the belts will
not slip at peak load conditions. For initial tensioning,
the proper belt deflection halfway between pulley
centers is 1/64 inch (0.4 mm) for each inch of belt
span. For example, if the belt span is 64 inches
(1626 mm), the belt deflection should be one inch
(25 mm) using moderate thumb pressure at midpoint
of the drive. See figure shown below.
mechanical fasteners. A periodic inspection should
include checking all fasteners and setscrews for
tightness. Particular attention should be paid to
setscrews or taper-lock bushings attaching the
propeller to the motor shaft and the motor shaft to
the bearings. Loose bearing setscrews will lead to
premature failure of the fan shaft. In addition, check
all fasteners attaching the motor to the motor plate.
Lubrication
Refer to the paragraph on bearings for bearing
lubrication. Many fractional horsepower motors
installed on the smaller fans are lubricated for life
and require no further attention. Motors equipped
with oil holes should be oiled in accordance with the
manufacturer’s instructions printed on the motor.
Use a high grade SAE 20 machine oil and use caution
not to over lubricate. Motors supplied with grease
fittings should be greased according to directions
printed on the motor.
Slack
Side
Check belt tension two times during the first 24
hours of operation and periodically thereafter. To
adjust belt tension, simply loosen four fasteners
(two on each side of the motor plate) and slide the
motor plate away from the fan shaft until proper
belt tension is attained. On some fans, fasteners
attaching the motor to the motor plate must be
loosened in order to adjust the belt.
Removal of Dust and Dirt
Dirt clogs cooling openings on the motor housing,
contaminates bearing lubricant and collects on
propeller blades causing severe imbalance if left
unchecked. The exterior surface of the motor, fan
panel and entire propeller should be thoroughly
cleaned periodically. Use caution and do not allow
water or solvents to enter the motor or bearings.
Motors or bearings must not be sprayed with steam
or water.
