IRIS Dampers

IRIS dampers are a brilliantly simple solution for fast and exact measurement, balance and control of airflow. They are ideal for supply and exhaust tracking control, individual comfort control, and any space requiring accurate airflow regulation. Applications for IRIS dampers include office buildings, pharmaceuticals, clean room environments, and laboratories. Its unique design allows for airflow to be measured and controlled at a single station, thus saving time and money in initial installation and commissioning, and those applications requiring air balance on a regular basis.

IRIS dampers are comprised of a casing, damper blades, an adjustment or regulating nut, and airflow adjustment chart, and airflow taps.  Blades and casing are manufactured from galvanized steel or 316 stainless steel (IRIS-S).  The remaining components are made from high strength plastics and rubber.
