Application of the Iris Damper


Iris dampers are typically used for controlling the air volume and measuring the circular duct in ventilation
and air conditioning systems. The diaphragm valve ensures a perfect accordance between a diameter

with no control mechanism in the airstream, thus allowing easy and effective cleaning of the duct work system.
