We aim to provide you with compressors that fulfill and even exceed your expectations and demands. Built as the result of decades of experience in oil-less design and manufacturing, the WIS oil-free range of water-injected screw compressors gives you all of this experience and knowledge in a class leading package. 

  • Certified 100% oil-free air – water-injected screw compressors provide 100% pure, clean air, complying with ISO 8573-1 CLASS 0 (2010) certification. CLASS 0 means zero risk of contamination; zero risk of damaged or unsafe products; zero risk of losses from operational downtime; and zero risk of damaging your company’s hard-won professional reputation.
  • Superior efficiency and performance – In your competitive production environment, being able to reduce costs is one of your main concerns. With IVR technology you obtain energy savings that will greatly downsize your electricity bill. By automatically tuning compressor capacity to the precise air demand, only a minimum amount of energy is required. 
    The highly effective cooling capabilities of water combined with precision engineering ensure the supreme energy efficiency and impressive FAD levels of the WIS compressors.
  • Water-inject screw technology – At the heart of the WISAIR range is a unique water-injected screw element 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.


Industries such as pharmaceuticals, food and beverages, electronics and textiles must exclude any risk of oil contamination.


For these applications, they need a technology that excludes any risk of contamination. Therefore, they look to ISO 8573-1 (2010) certification, in which Class Zero represents the best possible air quality. The only way to ensure oil-free air for your critical processes, is with an ISO 8573-1 certified compressor. 

Outstanding reliability, low maintenance and operating costs make the class zero compressors a sound investment. 

Class 0 means:
  • Zero risk of contamination
  • Zero risk of damaged or unsafe products
  • Zero risk of losses from operational downtime
  • Zero risk of damaging your company’s hard-won professional reputation.
