What is water injected screw compressor ?

  Water injected screw compressor is next generation product which combines advantages of both Oil injected screw compressor and ordinary 2 stage oil free screw compressor.

  Instead of oil, the compressor uses water for lubrication. So water itself acts as Lubricant, Sealing and Cooling function.

  Like oil injected screw compressor, it is mechanically simple, on top of that, the compressed air is OIL FREE.


What is the advantage of water injected screw compressor compare to oil injected screw?

  • Environmental friendly thanks to No oil lubricant usage
  • - No oil mist and odors

    - No disposal of drain included oil 

    - Cut the work load and cost of compressor user to take care of disposal of drain included oil

  • High quality Oil free air

What is the advantage of water injected screw compressor compare to ordinary 2 stage oil free screw?

  • High efficiency and performance with energy-saving

  • - Water as lubricant helps to reduce pressure loss and keep high compression efficiency

  • Simple structure

  • - 1 stage machine, No timing gear

  • Outlet compressed air stays low temperature
  • - Isothermal compression thanks to lubricate water

  • Minimum maintenance parts and low running cost

  • - Thanks to the simple structure
