Aluminum Alloy Air Control Damper/Volume Damper Material can be made of galvanized steel sheet and general plate Aluminum Alloy Air Control Damper/Volumer DamperApplication: The air control damper is usded in ventilation system pipe to control air volume . Also used for mixed new air and return air regulation.KC-SF manual volume damper is divided into two types: single-blade and multiblade ones.Used can control the wind volume by regulating the angle of the blades using the handle. Manual volume damper is usually installed in the square or rectangle-section windpipe.

The KC-DF is made on the base of manual volume damper, with its handle manipulation replaced by motor manipulation, in which, the motor manipulates the angle of blades to blades to control the wind volume using the connecting-rod mechanism. The size of the damper body can be made according to the customers' requirement.
