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.
Stocked in both Oregon and New York state. See transit maps below.
Some products might ship from multiple warehouses.
