Multi-leaf damper HK

Fields of application

Multi-leaf damper type HK can be used in air-conditioning and ventilation systems as control, throttle or shut-off dampers to control pressure and volumetric flow.


The flow-favouring blades are adjusted together, rotating in opposite directions, via external plastic gear wheels. The external arrangement of the gears has the advantage that, in comparison with internally arranged gears exposed to the air flow, they do not become soiled that quickly.

Volumetric flow range

400 - 25000 m³/h
