What are Plastic /Stainless Steel Exhaust and Supply Air Valves?
Both Plastic Air Valves (PAV) and Stainless Steel Valves (SSAV) have the same functions as the metal ones. They are designed to offer simple but effective means of providing air supply and air extract for most commercial, industrial and domestic ventilation applications. The only differences in contrast to metal valves are materials used and their construction. The plastic air valves and the stainless steel air valves can be used for both air supply and air exhaust (2 in [...]
Air valves are designed to offer simple but effective means of providing air supply and extract capabilities for most commercial, industrial and domestic ventilation applications. They are typically installed in hotels, houses, apartments, halls of residence and hospitals and are being used to handle air volumes in small confined and closed up indoor spaces such as toilets, washrooms, utility rooms, or any other small rooms.
What Are The Metal Exhaust and Supply Air Valves Made Of?
The body of an exhaust air valve is made of SPCC steel with thickness of 0.6mm or 0.8mm upon request.
The mounting ring of an exhaust air valve is made of DX53D+Z80 hot dipped galvanized steel (plated zinc thickness 6-8mm)
The exhaust air valve body has a gasket made of circular [...]

IRIS Damper is an ideal air flow regulator and measuring device for the circular ducts. The diaphragm valve ensures a perfect accordance between the diameter indication on the handle and the opening of the valve. When in a fully open position, the iris damper provides a 100% free area with no control mechanism in the airstream, allowing easy and effective cleaning of the duct.
Advantages of an Iris Damper (compared to the other VOLUME CONTROL DAMPERS)
Precise air flow measuring & regulating
Low sound level
100% open to facilitate duct cleaning
Air Tightness class C
Full size ranges from dia. 80mm to 800mm.
