Damper with flow meter IRIS HAVACO

Control damper, lenticular IRIS HAVACO is used for smooth regulation of air pressure in the ventilation duct. The special design in the form of a lever allows a smooth change of the diameter of the opening. Thanks to the lenticular closure, throttling does not cause turbulence and noise in the duct. IRIS throttle can be used in both exhaust and supply ducts. In addition, it is equipped with two terminals that allow the connection of a device measuring the air flow rate to the damper. The IRIS lenticular damper has the possibility of complete opening, which facilitates cleaning of ventilation ducts. There is no possibility of complete closure (the remaining gap diameter is about 25% of the nominal diameter).
