 ​​    

PRODUCT ADVANTAGES

1   Less Power, similar capacity, good energy saving

Less power consumption, high energy saving.

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 reduces compression ratio, reduce the leakage.


3    Heavy Duty Air Filter

  • Double filter core, improved filtration, long service life, large filtration area, low suction resistance, improved air inlet efficiency.

  • Made for dusty environments like:  cement, textile, fiber, chemical industry etc.

4    Oil/air tank(125HP-300HP)

  • Big capacity oil tank, reduced lubricating oil foaming. 

  • Tank cover fitted with lifting aid for simple air/oil separator replacement

  • Large air/ oil separator core, better separation, reduced pressure drop, higher system efficiency

  • Double oil separator core for 340HP and above, better oil separation.

  • Oil content< 3PPM over 4000 run hours.
