Product Details
Backdraft dampers are non-flanged horizontal mount exhaust backdraft dampers designed for various ventilation applications. The frame is constructed from galvanized steel, while the blades are made of aluminum and feature a felt seal on the leading edge to ensure quiet closing and enhanced weather protection. These dampers are spring-assisted, allowing the blades to open quickly, making them ideal for use in roof curbs, ductwork, or wall collars when paired with a fan or power roof ventilator. They are specifically recommended for horizontal mount exhaust applications and are proudly made in the USA.
