Product Description

Accessible in 16 different models, this Double Stage Screw Compressor is reckoned for its utilization of energy efficient motor, advanced control section, cutting edge safety control valve and filtration section with ergonomic design. This screw compressor is preferred over its single stage based version for its higher load enduring capacity. Suitable for large scale project purpose, this type of compressor requires uninterrupted supply of compressed air for its operation. Advanced oil leakage protection arrangement of this compressor promotes its oil injection process. We would like to introduce ourselves as a quality conscious manufacturer and exporter of Double Stage Screw Compressor. 

Double stage screw compressor

  • Two stage compression reduces each level of compression ratio and leakage, improving volume efficiency, so that reduced the bearing load, and improving the service life of the air end.
  • Two compression instead of single-stage compression, the exhaust volume increased by nearly 15%, can achieve more than 15% of the energy saving effect.
  • The rotor adopts the latest design patented line of UV rotor, after finishing 20 process, ensure the rotor profile accuracy, reliability and validity.
  • The first-stage compression rotor and the second-stage compression rotor are combined in one casing and directly transmitted through the helical gear, so that the optimal linear speed can be obtained for each stage rotor, and the compression transmission efficiency is the highest.
  • The compression ratio of each stage is reduced by the exact design of the bearing and gear load.
  • The patented oil lubrication system separates the compression chamber and the bearing oil separately. The compression chamber adopts the common cleanliness lubricating oil. The bearing part adopts the high cleanliness lubricating oil to ensure the high reliability of the bearing.
  • Level compression ratio is small Each the leakage is smaller the volumetric efficiency is high.
  • The same power the load is borne by two heads the bearing force is small and the life is longer. Under.
