Control damper for different airflow and duct pressure control applications. Pressure-independent operation.

Control damper for variable and constant airflow control applications in dual duct systems. Pressure-independent operation. Tight shut-off operation at closed damper position. Factory-set airflow range limits (min./max. airflow rates).

Constant airflow damper without external power supply, self-balancing operation. Large operation area.

Linear airflow control unit for constant low-pressure applications. Airflow characteristic is linear in relation to damper position and control signal.

Control damper for different airflow and duct pressure control applications. Pressure-independent operation. Factory-set airflow range limits (min./max. airflow rates).

Duct pressure control application. The static pressure control damper HFS is designed to be used in combination with static pressure measurement unit MSS to maintain the desired constant duct pressure.
