A Volume Control Damper (VCD) is a device designed to regulate and balance airflow within duct systems, chimneys, VAV boxes, and other air handling equipment. It provides accurate and reliable airflow control in ventilation systems.

Manual dampers are operated by an external handle mounted on the duct.
Automatic dampers regulate airflow continuously and are operated by electric or pneumatic actuators.
