Product Details
Backdraft dampers are non-flanged horizontal mount exhaust backdraft dampers designed for efficient operation. The frame is constructed from galvanized steel, ensuring durability, while the aluminum blades feature a felt seal on the leading edge to provide quiet closing and enhanced weather protection. These dampers are spring assisted, allowing for quick blade opening. They are ideal for use in roof curbs, ductwork, or wall collars in conjunction with a fan or power roof ventilator, making them particularly recommended for horizontal mount exhaust applications. All components are manufactured in the USA.
