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.

• Does not seal airtight.
• Multi-leaf damper with adjustable hollow profile blades.
• Frame and blades made of galvanised steel.
• Electrical or pneumatic motorisation possible.
• Optional: Certified according to ATEX Directive 2014/34/EU.
