Iris Duct Dampers - Air Controls 

   
 

Galvanized airflow regulator, specifically designed for circular ducts with nylon gear mechanism and rubber gasket on in- and outlet. Two manometer connections measure the differential pressure with a chart to calculate the values on either side whereby the removable key opens the blades.

It is recommended to install the damper at minimum twice the diameter from T connection or from outlet, and at minimum once the diameter from curves and inserted in ducts by 30mm each side for dia 200mm and inferior and by 40mm for the two larger sizes. Use in temperature -10°C to +80°C.
