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.
