Stamping Components HVAC Stainless Steel Uct Volume Iris Damper SGS Certification
Product Description
The body and valve of the iris damper are made of galvanized steel DX53 D+ Z275 or stainless steel 316L.
The seal ring has double lips made of EPDM rubber. Iris damper typically has a plastic regulator nut and a
plastic key.
The class of air tightness is a C class according to the EN1751:2014 and the color of the plastic quadrant
comes available in orange and yellow.
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.
