Additional Features
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.

BDD backdraft dampers are available in the spring-loaded and gravity style backdraft dampers. The spring loaded dampers feature a center pin design in 4 inch, 5 inch, 6 inch and 8 inch models and a center post design in 10 inch and 12 inch models. The gravity damper features a galvanized steel housing and aluminum butterfly damper blades.
