The WD-100 series are horizontally mounted backdraft dampers designed to allow vertical airflow up and prevent reverse airflow. The dampers are opened by air pressure differential (assisted by springs) and closed by gravity. Optional motor pack converts the dampers to motorized operation. The primary application is with roof mounted exhaust fans.
