   Down-to-earth investment for the future

  • Lower running cost is your gain.
  • Initial cost not a big issue, life cycle cost matters.

2    What you pay should be only for what you use

  • Matching your demand means no extra power used.
  • You pay for what you use and not generate.
  • Big energy saving.

3   Innovative motor oil cooling technology

  • Innovative closed loop oil cooled motor.
  • Special coolant and independent fan

4   Special Morse connection

  • Motor rotor is directly mounted on the air end rotor shaft.
  • Motor with no gears or belts, no shaft seal, no coupling.
  • Zero transmission loss.
  • Easy installation and dismantling.
  • No adjustment/ alignment required.
  • Reduced maintenance cost.

5   Double Frequency conversion system.

  • Constant pressure output.
  • Significant energy-saving.
  • Match to demand pressure and flow rate.
  • Constant temperature output

⑪ Electrical control cabinet

● Siemens core electrical components are used to further enhance reliability. 

⑫ All-steel internal pipe system

● All steel internal pipe work is used to prevent leakage and premature ageing often seen with flexible pipes

● Less pipe pressure loss 



Data conforms to ISO 1217 (Pressure 1 bar (a), Temperature 20 deg C, R.H 0%)

Standard voltage is 380V/50HZ/3P, other voltage is available.

The recommended best capacity range is 60%-100%.

Alpine/high altitude, high temperature, high humidity, high dust loads or other adverse working conditions will require specialized custom designs. These are available on special request.

We reserve the right to make changes and improvements to the design and appearance.

Specifications may change without prior notice.
