7. High accuracy and excellent adjustment properties.
Design & Material:
The damper is manufactured from galvanized steel sheet and is fitted with a rubber seal tested for air tightness.
Damper Mounting:
The damper must be installed in accordance with the distances required to minimize air flow deviation. Reducing or enlarging to the duct to the next duct size does not require any specified distances for minimizing deviation. IRIS 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,.
