The Iris damper finely balances a circular ducting system, while ensuring a very low leak rate (class C airtight performance).
Iris balancing damper
The Iris damper features a diaphragm for precise adjustment of airflow in a circular ducting system. This adjustment is made using a handle which operates a hexagonal nut. Lip seals at each end enable a ducting connection with a low leak rate.
The + products
- precise airflow control.
- class C airtight performance as per EN 1751
The Iris diaphragm is opened and closed using a handle which operates a hexagonal nut.
- airflow setting tolerance +/-10%,
- airflow / pressure measurement tap integrated (Ø 6 mm),
- class C product airtight performance as per EN 1751,
- temperature range: -20°C / +80°C.
- in circular ducts,
- the IRIS damper must be installed in accordance with the required distances to reduce deviation of airflow to a minimum,
-
the required distances to observe are:
- before bends: 1xD,
- after bends: 1xD,
- before T-pieces: 2xD,
- after T-pieces: 2xD,
- before diffusers: the 2xD.
