Technical Specs: BDD Backdraft DampersBDD 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″, 5″, 6″, & 8″ models and a center post design in 10″ & 12″ models. The gravity damper features a galvanized steel housing and aluminum butterfly damper blades.Features & Benefits of BDD Backdraft DampersSpring Loaded Backdraft DampersNeoprene damper seal minimizes leakage20 gauge steel housing, aluminum spring loaded butterfly damper bladesGasket designed to withstand temperatures from -22 F to 180 FRequires from 0.04 to 0.08 in. wg pressure to openSimple installation in any position – entire assembly inserts into ductExterior foam gasket assures a tight seal against duct4″, 5″, 6″ & 8″ sizes include stamped metal sleeve with center pin design10″ & 12″ sizes include rolled metal sleeve with center post design
