IRIS-S Stainless Steel Dampers are a brilliantly simple solution for fast and exact measurement, balance and control of airflow. It is ideal for supply and exhaust tracking control, individual comfort control, and any space requiring accurate airflow regulation. IRIS-S dampers are ideal for clean room or corrosive environment applications. 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-S Stainless Steel 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 316 stainless steel. The remaining components are made from high strength plastics.
The calibration accuracy of an IRIS damper during disturbance free airflow is 5%. However, when an IRIS damper is installed near duct fittings, measurement accuracy may be affected. For optimum operation and airflow control, the chart (Fig. 1) indicates the recommended distances between an IRIS damper and duct elbows, tees and transitions. From the chart, to achieve the airflow accuracy, m2, distance Lmin defines the minimum distance separating an IRIS damper from the fitting.
