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.

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.

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.

1. Follow all local electrical and safety codes, as
well as the National Electrical Code (NEC) and

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.

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.

6. Verify that the power source is compatible with
the equipment.

7. Never open access doors to a duct while the fan
is running.

Receiving

Upon receiving the product, check to make sure
all items are accounted for by referencing the bill
of lading to ensure all items were received. Inspect
each crate for shipping damage before accepting
delivery. Notify the carrier if any damage is noticed.
The carrier will make notification on the delivery
receipt acknowledging any damage to the product.
All damage should be noted on all the copies of the
bill of lading which is countersigned by the delivering
carrier. A Carrier Inspection Report should be filled
out by the carrier upon arrival and reported to the
Traffic Department. If damaged upon arrival, file
a claim with carrier. Any physical damage to the
unit after acceptance is not the responsibility of
Greenheck Fan Corporation.

Unpacking

Verify that all required parts and the correct quantity
of each item have been received. If any items are
missing, report shortages to your local representative
to arrange for obtaining missing parts. Sometimes it
is not possible that all items for the unit be shipped
together due to availability of transportation and
truck space. Confirmation of shipment(s) must be
limited to only items on the bill of lading.

Note: The filtered supply unit ships with all ordered
components completely factory assembled. The
optional weatherhood ships knocked down for field
assembly and installation.

Storage

Fans are protected against damage during shipment.
If the unit cannot be installed and operated
immediately, precautions need to be taken to prevent
deterioration of the unit during storage. The user
assumes responsibility of the fan and accessories
while in storage. The manufacturer will not be
responsible for damage during storage. These
suggestions are provided solely as a convenience to
the user.

INDOOR
The ideal environment for the storage of fans and

accessories is indoors, above grade, in a low
humidity atmosphere which is sealed to prevent the
entry of blowing dust, rain or snow. Temperatures
should be evenly maintained between 30° to 110°F

(-1° to 43°C), wide temperature swings may cause

condensation and “sweating” of metal parts. All
accessories must be stored indoors in a clean, dry
atmosphere.

Remove any accumulations of dirt, water, ice, or
snow and wipe dry before moving to indoor storage.
To avoid “sweating” of metal parts allow cold parts to
reach room temperature. To dry parts and packages
use a portable electric heater to remove any moisture
build up. Leave coverings loose to permit air
circulation and to allow for periodic inspection.

The unit should be stored at least 3½ inches

(89 mm)

off the floor on wooden blocks covered with moisture
proof paper or polyethylene sheathing. Aisles
between parts and along all walls should be provided
to permit air circulation and space for inspection.

OUTDOOR
Fans designed for outdoor applications may be

stored outdoors, if absolutely necessary. Roads or
aisles for portable cranes and hauling equipment are
needed.

The fan should be placed on a level surface to
prevent water from leaking into the fan. The fan
should be elevated on an adequate number of
wooden blocks so it is above water and snow levels
and has enough blocking to prevent it from settling
into soft ground. Locate parts far enough apart to
permit air circulation, sunlight and space for periodic
inspection. To minimize water accumulation, place all
fan parts on blocking supports so rain water will run
off.

Do not cover parts with plastic film or tarps as these
cause condensation of moisture from the air passing
through heating and cooling cycles. Fan wheels
should be blocked to prevent spinning caused by
strong winds.

Inspection and Maintenance During
Storage

While in storage, inspect fans once per month. Keep
a record of inspection and maintenance performed.

If moisture or dirt accumulations are found on parts,
the source should be located and eliminated. At each
inspection, rotate the wheel by hand ten to fifteen
revolutions to distribute lubricant on motor. If paint
deterioration begins, consideration should be given
to touch-up or repainting. Fans with special coatings
may require special techniques for touch-up or
repair.

Machined parts coated with rust preventive should
be restored to good condition promptly if signs of
rust occur. Immediately remove the original rust
preventive coating with petroleum solvent and clean
with lint-free cloths. Polish any remaining rust from
surface with crocus cloth or fine emery paper and
oil. Do not destroy the continuity of the surfaces.
Thoroughly wipe clean with Tectyl

®

506 (Ashland Inc.)
or the equivalent. For hard to reach internal surfaces
or for occasional use, consider using Tectyl® 511M
Rust Preventive, WD-40® or the equivalent.

Removing From Storage

As fans are removed from storage to be installed
in their final location, they should be protected
and maintained in a similar fashion until the fan
equipment goes into operation.

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.

• 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.

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.

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.
