Round transition multi-blade dampers PWR

Round transition multi-blade dampers PWR

PWR round transition multi-blade dampers are used for airflow control and shutoff in rectangular air ductwork. They offer a much finer control of airflow than the previously used single-blade round dampers. Working temperature: -20 to +90°C, (50°C with actuator).


PWR dampers are based on the PW damper, therefore standard designs of the PWR damper correspond to those of the PW damper. The square damper is equipped with round transitions that are suitable for connecting to a SPIRO system.


The construction of the dampers ensures very good air tightness characteristics in the closed position and a low airflow resistance when they are open.
