product advantages
  • 1 Less Power, similar capacity, good energy saving

    Compare with the standard compressor, the two stage screw compressor has better efficiency, it can save more than 10% energy compare with the standard compressor that both work at 100% loading.

  • 2 Isothermal Compression

    AFE31 is area of isothermal compression

    AC31 is area of standard compression

    AB,BF,FD,31 is area of two stage compression

    Two stage compression saving area is BCDF comparison with standard compression

    ★After first grade compression, the volume of compressed air become smaller, then the second compression could use smaller rotor, which reduce the compression leakage.

    ★It reduce compression ratio,  reduce the leakage.

  • 3 Heavy Duty Air Filter:

    Double imported safety filter core，improve air filtration effect, Long service life，Large filtration area, Low suction resistance，improve air inlet efficiency.  Specially for the dusty environment, like cement industry, textile industry, fibre industry, chemical industry etc. 

  • 4 Oil/air tank(125HP-300HP)

    Big capacity oil tank, Hold internal pressure, Reduce Lubricating oil producing foam. 

    Tank cover design with SCR rotating shaft, Simplify oil separator core replacement

    Enlarge oil separator core size , Better separation effect, Reduce the pressure drop during operating period, Improve system efficiency

    Double oil separator core is for big size type above 340HP and above, to help better oil separation.

    Oil content is less than 3PPM during 4000Hours running period.

Note:

The capacity is measured as GB3853 standard.(equivalent to ISO1217 Annex C)

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.
