The units are ready for connection and are easy to install, requiring no additional foundations. High air quality The large size of the tube cooler allows water cooler technology to replace conventional oil lubrication. This ensures absolutely no risk of contamination and a class 0 air output. What is an oil-free compressor? An oil-free compressor or oil-free air compressor is a type of air compressor that does not use oil for lubrication. This type of compressor runs at a lower speed, which makes them quieter and more efficient. What is the difference between an oiled and an oil-free compressor? Direct piston oil-free compressors differ from oiled compressors because they do not require oil to operate. Oil-operated air compressors are ideal for applications where high pressure and capacity are required. Oil needs to be added to the compressor to allow for higher RPM and to keep the compressor running at high speed. Oil-free air compressors do not require oil and are lighter in weight and easier to carry. This oil-free compressor is ideal for applications where noise and air quality need to be considered. Oil free piston air compressor applications and industries The laboratory, medical, electronics, dental and food and beverage industries benefit greatly from oil free piston air compressors because they are quiet and easy to maintain.
