Multi-Leaf Damper NK

Fields of application

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

Function

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