Multi-leaf damper JK
Fields of application
The multi-leaf dampers types JK are used in ventilation and air-conditioning systems as control, throttle or shut-off dampers to control pressure and volumetric flow. The multi-leaf damper type JK also allows air-tight sealing to DIN EN 1751, up to class 4.
The flow-favouring aluminium blades are adjusted together, rotating in opposite directions, via external plastic gear wheels. The external arrangement of the gears has the benefit that in comparison to internally arranged wheels exposed to the air flow, they do not become soiled so quickly.
