Fantech Iris Dampers

The IR Iris Damper is the ideal device for measuring and adjusting airflow through a duct. The design of the adjustable aperture ensures low turbulence resulting in minimal self-generated noise.

The damper is manufactured from galvanized sheet metal and is fitted with a rubber seal tested for air-tightness. The IR enables the taking of precise air flow measurements at all points including points close to duct deviations such as T-junctions and bends, and points in front of other supply-air devices.

#2 Q:   Can these dampers seal completely (or nearly completely)? What is the smallest hole size when fully closed?
