Options and Accessories
UL/cUL 762 - SWB Series 200 and
300 models are listed for grease
removal (UL/cUL 762). The UL/cUL
762 option includes a weatherhood,
threaded drain connection and
access door. Indoor mounting
requires the fan to have welded
scroll construction.
Weatherhood - Available to completely cover the motor
and drive compartments; protecting the shaft, bearings,
motor and drive components from moisture and other
adverse weather conditions. Weatherhoods are vented to
provide sufficient motor cooling, designed to meet OSHA
guidelines and are easily removed for service access.
Series 300 includes an access door.
Drain Connection - Threaded drain connections can
be provided to drain moisture from the bottom of the
fan housing.
Grease Trap (SWB Only) - Aluminum trap is designed
to collect grease residue and avoid drainage onto roof
surface. Disposable grease absorbents are available for
easy maintenance.
Access Doors - Access doors provide access for
inspection and cleaning. Either bolted or hinged, quick
opening access doors are available on all models except
SFD. (Series 100—bolted option only)
Welded Scroll Construction - Welded scroll
construction is available on SWB Series 200 and 300.
Aluminum Construction - Aluminum airstream option is
available on SWB Series 200.
Dampers - Gravity or motorized
parallel blade backdraft dampers
feature sturdy galvanized frames with
prepunched mounting holes, aluminum
blades with felt edges and balanced
design for minimal resistance to
airflow. Backdraft dampers are not
suitable for downblast or bottom
angular downblast discharge positions. The fan must
be supplied with a flanged outlet to install a backdraft
damper directly to the fan. Heavy-duty dampers are
available for high pressure applications on fans with
motors equal to or greater than 7
1 ⁄
2
horsepower.
Disconnect Switches - A wide selection
of NEMA rated switches are available
for positive electrical shutoff and safety,
including: dust-tight, rainproof and
corrosion-resistant.
Wiring Pigtail - Allows direct hookup to the power
supply eliminating field wiring to the fan.
Extended Lube Lines - Lubrication lines with grease
fittings are extended from shaft bearings to the base
of the drive frame panel or weatherhood for easy
bearing lubrication.
Inlet and Outlet Guards - Constructed
of expanded metal mounted in a steel
frame to provide protection for non-ducted
installations. The guards can be easily
removed for fan maintenance or inspection.
Flanged Inlet and Outlet - Flanges are available for
damper mounting or flanged duct connections. Inlet
flanges have prepunched mounting holes. Outlet flanges
are bolted on standard; welded for UL 762 applications
Companion Flange - Connects to the inlet flange and
then attaches to the ductwork. Recommended for slip-fit
duct connections.
Inlet Vane Dampers (SWB only) - External inlet vane
dampers are available on model SWB fans, sizes 112–
124 and 212–224. External vanes are mounted on the
inlet flange. Inlet vane dampers feature
zinc-plated steel blade axles, stainless
steel washers and bearings. Vanes can
be used for either manual or automatic
operation, with controls furnished
by others. Maximum operating
temperature is 200°F
(93°C) .
Coatings - A wide variety of coatings and
colors are available for decorative to acidic applications
on SFB and SWB Series 200 and 300. All Greenheck
coatings can be found in the Performance Coatings for
Commercial and Industrial Fans publication.
Permatector™ is our standard coating. Typically
used for applications that require corrosion
resistance in indoor and outdoor environments.
Hi-Pro™ Polyester is resistant to salt water,
chemical fumes and moisture in more corrosive
atmospheres. Typically used for applications
requiring superior chemical resistance, excellent
abrasion and outdoor UV protection. This coating
exceeds protective qualities of Air Dried Heresite
and Air Dry Phenolic.
Baked Enamel Decorative Coatings are heat
cured enamels applied as electrostatic powders.
Customers can choose from 16 standard
decorative colors or color match any color.
Heat Slinger and Shaft Seal (all belt models) - Heat
slinger is an aluminum cooling disc mounted on
the fan shaft between the inboard bearing
and the fan housing. The disc dissipates
heat conducted along the fan shaft.
The shaft seal with an aluminum rub
ring is available for applications where
contaminated or high temperature air is being handled. ed on
