WIS 20-75hp Oil-Free Water Injected Screw Compressors

WISAIRƒ??s water injected screw offers the most innovative oil free technology and improved energy efficiency thanks to the superior cooling capability of water. Removing the wasted energy that heat represents gives more air per kW of power. The low temperatures of the compressed air reduces the stress on components ensuring long life. the WISAIR range is certified to ISO 8573-1 Class 0.


At the heart of the wisAIR, there is the water-injected
screw airend producing highly efficient near isothermal compression. The
polymer ceramic rotors with their optimized rotor profile are supported by
water-lubricated bearings, ensuring that no oil contaminates the compression
element, thereby producing pure oil-free air. The wisAIR comes standard with an
advanced graphic controller. Configurations include air and water-cooled
versions, multiple pressures and an optional integrated dryer.
