Water injected screw compressor is a next generation product which combines advantages of both an oil injected screw compressor and an ordinary two stage oil free screw compressor.
Instead of oil, the compressor uses water for lubrication. So water itself acts as lubricant and a sealing & cooling method.
Like oil injected screw compressor, it is mechanically simple, on top of that, the compressed air is OIL FREE.
- 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 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
- Isothermal compression thanks to lubricate water
Minimum maintenance parts and low running cost
- Thanks to the simple structure
