  • Oil-free water-injected screw air compressor
    Patent number: 11686308
    Abstract: An oil-free water-injected screw air compressor comprises a housing that encloses two rotors for generating compressed air, and an air water separator for separating the water from the compressed air. Water injection can effectively cool a compressor, and some embodiments provide a sealing system for isolation of compressor bearing lubricant from water used for cooling.

  • OIL-FREE WATER-INJECTED SCREW AIR COMPRESSOR
    Publication number: 20220003234
    Abstract: An oil-free water-injected screw air compressor comprises a housing that encloses two rotors for generating compressed air, an air water separator for separating the water from the compressed air. Injecting water during compression can remove the heat of compression and thus enhance efficiency of compression. However, injecting water may complicate bearing lubrication. According to the present subject matter, these challenges are tackled using a sealing system for isolation of bearing lubricant from water used for cooling.
