Double Stage Oil Free Airends

Dry running screw compressor airends

Decades of experience in the construction of compressor design enable us to deliver leading oil free air screw compressor airends. The compressor stage is directly flanged onto a gearbox, resulting in an integral solution including oil-tank, oil-pump and oil-filter. Protection of corrosion in the compression chamber is reassured with the application of unique ULTRACOAT. The second stage or the high-pressure stage is flanged onto the gearbox beside the low pressure stage. Mounted on anti-friction bearings the rotors run absolutely free without contact.

Caratteristiche

High performance reliable 2-stage oil free compressor blocks for continuous operation in demanding applications including: chemical, automotive, pharma-ceutical, food and beverage industries, air separation systems, etc.

  • Totally oil free air compression
  • Lifetime compression efficiency: rotors and internal housing surfaces treated with Ultracoat (Our coating prevents corrosion and improves efficiency of the compression process. Ultracoat has an
  • exceptionally long life and is resistant to high temperatures and pressures.)
  • No corrosion due to stainless steel rotors in the high-pressure-stage
  • GHH RAND rotor profiles for high efficiency
  • Robust design reliable in operation under the most difficult conditions
  • Over 60 years market experience in oil free compressor units!
