Siegwart multi-leaf dampers for precise airflow control

Multi-leaf dampers are used wherever air flows need to be efficiently regulated or shut off – whether in ventilation systems, industrial air ducting systems or building services engineering. The flexibly adjustable blades of the multi-leaf damper enable precise control of the volume flow and contribute significantly to energy efficiency and a pleasant indoor climate.

Function and areas of application of the multi-leaf damper

The multi-leaf damper consists of several overlapping blades that can be adjusted manually or by motor. Depending on the opening angle, they regulate the air flow continuously – from completely closed to fully open. They are ideal for:

Ventilation and air conditioning systems in commercial and industrial applications

Exhaust air systems in production or laboratory environments

Supply air ducts with individual air volume requirements

Thanks to their compact design and high robustness, Siegwart multi-leaf dampers can be flexibly integrated into a variety of ventilation systems.
