Circular Air Dampers

Features and Applications

Circular air dampers are mechanical control elements used in round duct systems to regulate, direct, or shut off airflow. They are typically manufactured from galvanized steel, aluminum, or stainless steel. Available in single-blade or multi-blade configurations, they can be operated via manual lever, geared mechanism, or motorized actuator. Sealed designs with gaskets are preferred to ensure airtight performance. They provide low pressure drop, improving overall system efficiency.
