Regulation of Airflow: Collar Dampers are used in HVAC systems to regulate the volume of air passing through ducts by adjusting the damper blade position.

Adjustable Design: They feature adjustable blades or dampers that can be manually or automatically controlled to modulate airflow.

Installation: Typically installed within ductwork, either near air outlets or junctions, to control airflow to specific zones or rooms.

Materials: Constructed from durable materials such as galvanized steel or aluminum to withstand the rigors of HVAC system operation.

Energy Efficiency: By controlling airflow, Collar Dampers contribute to energy efficiency by ensuring that conditioned air is directed where it's needed most, reducing energy waste.
