The VAV damper HFB contains an averaging airflow measurement probe, airflow controller and actuator. Airflow is controlled based on actual flow measurement by changing the damper
blade position. Flow control damper HFB maintains the required airflow independent of duct pressure variation.
HFB airflow control damper is available in several versions. The blade gasket enables airtight shut-off operation, and external insulation is used to attenuate radiated sound into the space.
Control damper for different airflow and duct pressure control applications.
Galvanised steel design.
