BDD backdraft dampers improve comfort and save energy and money by keeping unwanted air from entering a duct when a fan is not operating. This can be very beneficial in keeping outside air from being drawn into a room, or preventing the reversal of indoor air when a number of fans are joined to exhaust through a common duct.  Utilizing a backdraft damper in this manner prevents air that is being exhausted from one area from backing up into other areas connected by the common duct.

The gravity damper features a galvanized steel housing and aluminum butterfly damper blades.
