A Damper is a blade or plate that can stop or regulate the flow of air inside a duct, or other air handling equipment. A damper can be used to cut off central air conditioning (heating and cooling) for an unused room, or it can regulate it for room-by-room temperature and climate control.

Barclay Engineering Dampers can be designed for manual or automatic operation ( Pneumatic or Electric )

Manual Dampers are turned by a handle on the external part of a duct. 

Automatic Dampers are used to regulate airflow and are operated by electric or pneumatic motors.
