OPTIONS/ACCESSORIES
Automatic Belt Tensioner: Available on sizes 8-24,
The Automatic Belt Tensioners eliminate the need for
regular manual retensioning of drives, and the risk
of inadvertently over-tensioning drive components
is avoided and overall drive operating efciency is
enhanced. Benets include reduction in startup and
maintenance costs, increased belt life, increased drive efciency, and ensure drive components do
not snag obstructions.
Roof Curb: Prefabricated heavy-gauge galvanized steel, welded construction,
12” high (other heights are also available) with 1-1/2” wood nailer. Assures perfect
t of exhauster to roof opening. Options include burglar bars, single or double pitch
construction and hinged curbs for easy duct access.
Common Curb: Designed to allow both the supply fan and exhaust fan to be mounted on the same
curb. This curb requires only one roof opening and speeds installation time.

backdraft. (Not for UL762 use).
Automatic Damper: Automatic aluminum damper for ease in installation and effective
backdraft protection. (Not for UL762 use).
