The WD-300 series backdraft damper prevents reverse airflow in horizontal exhaust applications. Model WD-300 has a flange on intake, model WD-320 has a flange on discharge and model WD-330 does not have a flanged frame. Dampers open using air pressure differential and close by gravity. Optional mot
The WD-200 series backdraft dampers are motorized to open when energized and the spring return closes when de-energized. Model WD-200 has no flange, model WD-210 has a flange on the motor side and model WD-220 has a flange opposite the motor. The WD-200 series is for horizontal or vertical mounting
The WD-100 series backdraft dampers mount horizontally to allow vertical airflow up and prevent reverse airflow. Model WD-100 has no flange, model WD-110 has a flange on the discharge side, and model WD-120 has a flange on the intake side. These dampers open using air pressure differential (assiste
