WALL HOUSING: This heavy-gauge, all galvanized G-90 steel (aluminum optional) housing provides a
simple solution to installing a fan and all specied accessories in a rough wall opening. It can be used
in exhaust or supply applications and maintains the proper clearance between the fan and damper.
Depending on space and maintenance requirements, the wall housing may be installed projecting inside
or outside of the building. All housings ship assembled with the fan to lessen job site installation costs.
Wire motorside guard, damper or propeller side guard and rainhood may be attached to the ange. We
strongly recommend a rainhood and motorized shutter for all supply applications and whenever additional
weather resistance is desired.
