Oil free air compressor Oil-free screw air compressors are widely used in industries that require high quality air sources such as : pharmaceutical,food, electronics, chemical,packaging,etc. 100% pure compressed air is a necessary procedure to guarantee satisfactory crafts and product quality, which ensures the production of high-end products safely and risk-free. The lubrication system of an oil free screw air compressor is an individual fuel recycling unit, the compression chamber and the bearings were separated by a set of sealed high-performance mechanical assembly. The lubricating oil can only flow in the enclosed area and is prevented to enter the compression chamber, which only contains 100% pure compressed oil-free air.The users could obtain 100% pure compressed air with some slight post-treatment of water and dust removal.
