CompAir DH Series Oil-less Rotary Screw Compressors combine 100% oil-free construction and variable speed technology to provide an energy and cost efficient oil-free solution. 

Low operating temperatures and maintenance free sealed bearings eliminate the need for lubricating oil in the compressor.  In addition to its oil-free distinction, CompAir DH Series is referred to as an oil-less line because it contains no oil in the compression chamber nor anywhere else in the package.      

At the heart of the compressor package is a high output single screw compression element which uses water injection technology for lubrication and cooling.  Simplified construction and reduced component count decrease the number of moving parts, which drastically improves reliability.    

Available in both air-cooled and water-cooled options.
