AIR CONTROL CONTROL DAMPERS AND BACKDRAFT DAMPERS Air control dampers regulate airflow through ductwork by opening and closing their blades. They feature automatic air control and manual balancing for low- to high-pressure and velocity applications. Backdraft dampers allow airflow in only one direction, preventing unwanted outside air and wind from entering the building, plenum, or built-up unit. CONTROL DAMPERS Control dampers are an integral part of every HVAC system. They are positioned manually or automatically to control air volume, pressure and temperature throughout the air handling system.

BACKDRAFT DAMPERS Backdraft dampers employ gravity-operated extruded-style blades to restrict reverse airflow while allowing air to flow freely in the intended direction. They can be mounted vertically or horizontally (airflow up) in either exhaust and intake installations.
