The FAMCO Butterfly Damper is one of the easiest, least complicated dampers on the market. It is used as a backflow damper in forced air systems, solar systems and exhaust/intake systems. It has no metal hinges or springs to rust or break and is maintenance free. The BD has a foam seal providing minimal air leakage. Due to its unique design it opens easily with normal air flow - closes by gravity. It will work in either horizontal or vertical positions (except vertical down).
