Butterfly Backdraft Dampers

Butterfly Backdraft Dampers prevent the flow of outside air into a house through ducting when either an exhaust fan or intake is off. These sensitive butterfly dampers will accomplish this with minimal effect on the exhaust stream while providing a good seal against backdrafts.
