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.
