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
before bends 1 x Diameter.
after bends 1 x Diameter.

The IRIS is composed of regulation plates, regulating nut or handle (size 80) and regulation scale plus manometer connections and casing.
The casing and regulation plates are made of hot galvanized steel (standard IRIS) or acid-proof steel AISI 316 L (IRIS-S), other components of plastic. The joining collars are supplied with rubber sealing gasket.
IRIS is an ideal solution for the exact and quick air flow measuring and regulation.Because of its acid proof material, the IRIS-S is best suited for premises, where acid proof ducts are used.
The IRIS damper is secured to the ducting with rivets. For vertical mounting ensure the weight of the interconnecting ductwork is fully supported.Refer to page 5 for recommended safety distances
