Spring-loaded Butteryfly backdraft damper 

Backdraft dampers are used to let air flow out of it, when the air flow stops gravity takes over and the backdraft damper closes and will prevent contaminated air to filter back through it. A backdraft damper is used on heat exchangers, exhaust systems, solar heating systems; and can be installed in either a horizontal or vertical position with minimal leakage.
