Heavy-gauge galvanized steel and zinc fan housing promotes durability and is treated with a rust proof paint to impede oxidation. Adjustable mounting brackets (up to 26 inches), detachable adaptors, and a double-hanger bar system are all included to make the installation process user-friendly and trouble-free. Built-in backdraft damper prevents chilly, outside air from entering. Internal configuration of components allows the condenser motor to operate at cooler temperatures, preventing degradation and increasing the lifespan of the motor and bearings. UL Listing permits use in tub and shower enclosures when used with a GFCI branch circuit wire.
