    Mr.Kerry Robinson from Australia
    today I ran the compressor and I am very happy with the workmanship and the quality , it is connected to a nitrogen generator that requires around 0.8 MPA feed air from the 30 kw compressor we are commissioning it I have found that it loads and unloads from 25.5 kw - 30 kw this will be a huge saving on power consumption.

Product Description

Shanghai Rotorcomp supplying oxygen compressor is completely oil-free and does not use any lubricating oil.
The cylinder uses stainless steel and the piston ring is self-lubricating. All these ensure the cleanliness and pollution-free of oxygen.
The working speed of the compressor is very slow, usually 200-400 rpm, suitable for continuous working conditions for 24 hours.
Generally, according to the customer’s oxygen usage, our oxygen compressors have one-stage compression, two-stage compression, three-stage compression, four-stage compression, and five-stage compression in the form of cylinders, which are single-cylinder,

Thanks to their oil-free, dry-running and gas-tight design, Shanghai rotorcomp compressors are ideally suited for use in the compression of oxygen.

  • no gas contamination due to oil-free and dry-running compression
  • Safe operation through the use of special, oxygen-compatible materials
  • technically tight gas compressors during operation and at standstill


  • Completely oil-free and dry-running piston compressor
  • Gas-tight design with integrated motor
  • Environmentally friendly because it is oil-free, gas-tight and efficient
  • Compressor leak rate < 0.0001 mbar l/s
  • Air-cooled
  • Motor powers from 3 to 44 kW
  • Rotary speed range 200 to 1700 1/min
  • Suction pressure max. 40 bar(abs)
  • Final discharge pressure max. 200 bar(abs)
  • Modular cylinder configuration with cylinder diameter up to 75 mm
  • Version with 1 cylinder for 1-stage compression
  • Maximum flow rate at atmospheric suction pressure approx. 150 Nm3/h
  • Booster-version flow rate max. approx. 50 Nm3/h
  • OEM block version available without pipework and instrumentation for integration in an OEM system
  • Very robust and long-lasting construction
  • Compact and foundation-free installation
  • Very quiet and hence suitable for installation directly at the workplace
