Industrial Oil-Free and Oil-Less Air Compressors
John Henry Foster of Eagan, Minnesota, distributes industrial oil-free and oil-less air compressors and provides air compressor maintenance and compressor parts on all brands and parts of compressed air systems in the greater five-state area including Minnesota, North Dakota, South Dakota, Wisconsin and northern Iowa.
In an oil-free compressor, the air is compressed entirely through the action of the screws, without the assistance of an oil seal but oil can be found on the machine. In an oil-less air compressor, no oil is present in or on the compressor.
