Multi-Leaf Damper NK

Domenii de utilizare:

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.

Funcţionare

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.
