Product Introduction:
The iris damper is an ideal air flow regulator and measuring device for circular ducts, the diaphragm valve ensures a perfect accordance between the diameter indication on the handle and the opening of the valve, in the fully open position the iris damper provides 100% free area with on control mechanism in the airstream allowing easy and effective cleaning of the duct work system. Available in sizesφ80-800mm
Product Features:
1. Quick and simple installation and maintenance.
2. Extended spigot connections
3. 100% opening capacity
4. Low noise generation
5. Good air tightness
6. Linear choking for simple operation
7. High accuracy and excellent adjustment properties.
Material:
The body and valve are made of galvanized steel sheet
Seal ring is made of EPDM
Composition:
Body and valve are made of galvanized sheet steel
Plastic regulator nut with plastic key
Measuring point on either side of the valve for connection of manometer.
Sticker with selection graph, mentioning the air volume at the different opening positions of the valve and the according pressure level.
Flexible joints for air tightness when placed inside the duct.
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,.

Construction
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.
Use
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.
Installation
The IRIS damper is secured to the ducting with rivets. For vertical mounting ensure the weight of the interconnecting ductwork is fully supported.
Protective Distance:
before bends 1 x Diameter.
after bends 1 x Diameter.
before T-pipes 3 x Diameter.
after T-pipes 1 x Diameter.
before supply-air devices 3 x Diameter.
