VENTS has optimized the range of round and rectangular dampers of KRA and RRV series.
The actuated damper models KRA and KRAF with a return spring and various actuator models were substituted with the unified KRV air damper compatible with various actuators. The KRV model is equipped with a specially designed plate for actuator fixation and an elongated shaft for mounting of any actuator types.
The KR damper model design was also modified. This damper is featured with a handle for manual regulation of the damper position.
Rectangular duct dampers
The KRA and KRAF models are taken out of production.
The model RRV without actuator, the RRVA model with actuator, the RRVAF model with actuator and return spring were substituted with a unified RRV air damper that is compatible with any actuator type. The RRV model is equipped with a specially designed plate for actuator fixation and an elongated shaft for mounting of any actuator types.
The Belimo actuators as described in Electric Accessories section of the Industrial Ventilation Catalogue, are available on separate order.
As a result of this damper range modernization a single air damper is used as a basic model and various actuator types are selected depending on the project and operating conditions.
