WD-100 20x20 Backdraft Damper Horizontal Mount, Vertical Airflow Up

Item #GRF20.20WD100

: 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 on sizes larger than 12 in. x 12 in. [305 mm x 305 mm]) and closed by gravity. Optional motor pack converts the dampers to motorized operation. The primary application is with roof mounted exhaust fans.
