Quincy Compressor WIS Oil-Free Water Injected Screw Compressors

Quincy Compressor WIS Oil-Free Water Injected Screw Compressors 20-75hp Oil-Free Water Injected Screw Compressors WISAIR’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.

The power of our oil-free screw range

WIS 20-75V oil-free compressors provide high-quality compressed air for a range of industrial applications. The continuous investment in product development has resulted in both economical and ecological compressors. The range is built focusing on three pillars to make them stand out.

Oil-free quality air

  • Ultimate 100% oil free, clean air.
  • The integrated air dryer enhances the air quality and protects your air network against corrosion.

Energy efficiency

  • The most energy efficient compression due to low air discharge temperatures, optimized rotor profiles and no bearing losses.
  • Integrated inverter technology assures a perfect match of air supply and air demand eliminating no load power losses.
  • Direct driven no loss drive train.
  • Graphic, full color screen controller with intelligent energy saving features.

Ultimate reliability

  • Friction free hydrodynamic bearings lubricated by clean, filtered lubricant.
  • Durable materials to exclude any risk of corrosion.
  • Reduced rotor stresses due to soft start up process.
