Diaphragm flow control damper IRIS used for adjusting and measuring airflow in ventilation systems.
Execution diameter: Ø 125 mm
Designed for direct installation in ductwork, especially round ducts.
Unlike traditional throttle or blade dampers, this design operates on the principle of a diaphragm – the cross-sectional area of the air decreases or increases uniformly in a circular shape.
Advantages and Application
- More stable airflow.
- High accuracy in airflow regulation — the damper allows you to precisely set the required volumes of air.
- Suitable for balancing ventilation systems so that supply and exhaust air are balanced.
- Ability to integrate into various ductwork systems due to different diameters.
- Reduced noise level in the ductwork.
