Broan 764WH is a ventilation fan with light that can be used for general ventilating purposes, but not for exhausting hazardous or explosive materials and vapors. It is designed for installation in flat ceilings only and must be grounded. The product is U.L. listed, Type I.C. inherently protected. It features a glass light shade, a permanently lubricated motor, and a counter-balanced damper flap that prevents air from entering the unit or finished space when there is a backdraft. The fan can be used with a dual control switch box and comes with a grille pan and mounting hardware.
