PRODUCT ADVANTAGES

   Low pressure air end

High efficiency air end profile, specially designed for low pressure application, like textile, cement, glass industry, etc.

Big air end with 1500 RPM help get better performance, and extended life.

   High efficiency PM motor with VSD technology.

Atrotech low pressure compressor with VSD drive and PM motor, help energy saving and reduce life cycle cost.

   Heavy Duty Air Filter:

Two stage filter element, longer service life, low suction resistance, improved air filtration efficiency. Specially designed for cement, textile, fiber, chemical industry, etc. 

  Oil/Air tank

  • Big capacity oil air tank, no foaming.
  • Easy access to oil/air separator and its replacement.
  • Large air/oil separator element, lower pressure drop, longer life and reduced cost.
  • Double oil separator element for 340HP and larger, better oil separation.
  • Oil content below 3PPM over 4000 hours running period
