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 indication on the handle and an opening of a valve. A fully opened iris damper provides a 100% free area with no control mechanism in the airstream, thus allowing easy and effective cleaning of the duct work system.
Mounting of the Iris Damper
Iris damper is to be mounted between the two ducts according to the mounting instructions. Once mounted, an iris damper can be set on a desired air volume according to the set-table (joined with each damper).
