ROTARY SCREW AIR COMPRESSORS Our lubricated and oil-free rotary screw compressors incorporate the very latest technological advances and guarantee a continuous supply of high quality compressed air. The screw compression element is designed and manufactured in-house, using the latest CNC rotor grinding machinery. BENEFITS: • Operate in the most extreme temperatures, between -47º to 55º C • Save floor space with an optimized footprint • Offer simple “Plug & Play” Installation ROTARY SCREW COMPRESSOR TECHNOLOGY. PRINCIPLE OF OPERATION The screw compressor is a rotary, positive displacement compressor with two axles. The screw compression element is the heart of the compressor. Both the male and female rotors have optimally matched screw-shaped lobes that are very close together and run in the rotor housing that surrounds them closely. Screw compressors do not have any pulsating parts such as pistons, rods and valves. This facilitates lower vibration operation as far as possible and lowers dynamic loads on supports and coupling. The relatively low number of mechanical parts, especially closure parts, means the risk of a machine break-down is very low. Unlike piston compressors which use the same principle of compression, the screw element is not equipped with valves. As such, it can work at a high shaft speed and there are no mechanical or volumetric losses to create imbalance. This means that screw technology can combine a large flow rate with a compact, space-saving design. OIL-FREE SCREW MODELS Unlike oil-flooded compressors, compression in the compressor stages is completely “dry.”
