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  
Sidewall Propeller Fans • Exhaust, Supply and Filtered Supply

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.

WARNING  
Always disconnect, lock and tag power source before  
installing or servicing. Failure to disconnect power  
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.  
Support Braces  
Wall Housing sizes 42 and larger with heavy motors  
and all Filtered Supply Wall Housings need additional  
bracing.  
Position weatherhood over end of wall housing  
and fasten through mounting holes with self-  
tapping screws. Caulk, flash and complete  
electrical hook-up to finish installation.

The propeller should rotate freely and not rub on the  
fan panel venturi. Rotation direction of the propeller  
should be checked by momentarily turning the unit  
on. Propeller blade should cup and throw the air  
when rotating in the correct rotation as shown in  
the figure below. Rotation should be in the same  
direction as the rotation decal affixed to the unit.

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.
