Fantech IR 5 - Manual 5" Duct Iris Damper


The Fantech IR 5 Iris Damper is used for adjusting and measuring the airflow in ventilation systems and for exhausting air.


The Fantech IR 5 Iris Damper is manufactured with galvanized steel sheet. It has an adjustable aperture, which allows the damper to control the airflow and thus achieve precise balancing of the ventilation system. It also helps to maintain low turbulence and minimal self-generated noise. The aperture opens up completely, making the 5-inch diameter duct accessible for maintenance and cleaning without any access door. This iris damper also features a calibrated airflow measuring device that takes accurate measurements at precise points and permanent pressure taps. The Fantech IR 5 can also be used in exhaust fans and is easy to install owing to its compact construction. When installing the damper, the distances required to minimize air-flow deviation should be taken into consideration.
