100% oil free water injection screw air compressor for medicine production and package use

From the production of tablets to the application of preservatives, during filling and dosing. Compressed air is usually in direct contact with the product or package. Zero-grade oil-free air prevents oil from being transferred directly to the product. For process-grade aseptic air requirements, zero-grade oil-free air is essential. Royal machinery Zero-grade 100% technology Reduced product safety issues.

Product Description


High reliability of oil free screw air compressor

  • Oil free screw compressor applies rotary single screw air-end.
  • By being in market every since 1982, it has undergone practical for over 30 years, all of it’s air quality, power saving and high reliability features have turned out to be state of the art in design and performance.
  • Air and water are becoming a major trend in compressor market due to their high compatibility, availability, reliability and environment friendliness.



High efficiency (lubricated water)

  • Lubricant water functions
  • Serves as sealant, coolant and lubricant.
  • Sealing function reduces/seals “blow hole” between rotors and housing to absolute minimum, ensuring efficient compression with delivered air volume per horse power increased by 15% as compared to general dry-type screw units.
  • Lubricant water also very effectively absorbs and dissipates heat generated during compression process.




Near isothermal compression(oil free water lubricant screw air compressor):

  • Thermal energy and water film, arising from the compressed air cooled by the lubricant water that has being injected into the compression chamber, seals up rotor gaps to prevent air back flow. The ideal isothermal compression thus achieves optimum efficiency. Theoretically, when air at 20℃ is compressed to 7kg/cm2G in a thermal isolation process, the discharge air temperature will be over 250℃, injection of lubrication water that has a cooling effect, into the compression chamber will bring the temperature down to about 40℃, achieving high efficiency ideal isothermal compression.
