HVAC Air Duct Manual Balancing Damper IRIS Damper
IRIS Damper Brief Introduction
The IRIS is composed of regulation plates, regulating handle and regulation scale plus manometer connections and casing.
The casing and regulation plates are made of hot-galvanized steel (standard IRIS) , other components of plastic.
The joining collars are supplied with rubber sealing gasket.
1.Regulation and measurement of air flow
2.The regulation plates form a virtually ideal measuring orifice which enables an easy and reliable measurement of the air flow.
3.To determine the air flow, measure the pressure difference Δpm at the manometer connections and check the corresponding air flow from the regulation chart.
4.The chart is shown on the damper casing and in the separate information for air flow regulation and measurement (the selection diagrams do not serve the air flow measurement).
5.Air flow is regulated by the regulating nut or handle.
