product advantages
  • 1 Germany GHH-RAND Oil Free Airend.

    Two Stage Dry Compression, The first-grade rotor is E35 steel. The second-grade is stainless steel, it’s 100% oil free during compression process. 

    Ultra Coating at rotor surface, make sure the tolerance of airend.

    Stainless steel hermetic seal and labyrinth oil seal. Double protection method to guarantee 100% oil-free compressed air.

    Direct energy saving

  • 2 Centrifugal fan

    As for air cooling type, it take use of centrifugal fan, which has low noise, high wind pressure features, more environment friendly.

    Variable frequency soft start

  • 3 Air inlet system

    Independent inlet silencer box, Ensure the air filter inlet temperature equal to the ambient temperature, which will help reduce the power consumption. At the same time, it isolate the noise inside of this box, so help reduce the noise level a lot.
