A water-lubricated oil-free fixed speed screw air compressor is a type of air compressor that uses water as a lubricant instead of oil. This type of outstanding oil free air compressor is designed to provide a continuous supply of compressed air that is free of oil contaminants, making it ideal for applications where clean, oil-free air is required.
