1200 Extruded Aluminum Backdraft Damper (Formerly BDD)

The Ventex 1200 (In-Duct Frame)/1205 (Flange Frame)/1207 (Front Flange Frame) is a superior concept in back draft dampers. This unique AMCA Licensed, all-aluminium product eliminates the shortcomings of previous designs on the market. Pivot pins that quickly wear out or rust out, or rivets that shake loose and pull through the blade are no longer a problem. The extruded blades are engineered to combine strength and durability with smooth operation by virtue of their aerodynamic design. For motorized operation see Model Series 1300.
