ABSTRACT:
An apparatus for providing relatively dry, oil free compressed instrument air includes a first compressor for receiving air at ambient temperature and pressure and compressing it to an elevated pressure. A cooler is provided for cooling the compressed air while a vortex directs its cold fraction discharge air to a second compressor. A heat exchanger is disposed intermediate the cooler and the vortex tube for transferring heat from the cooled, compressed air to the cold fraction discharge air. An air-water separator may be disposed between the vortex tube inlet and the heat exchanger for removing any condensed water from the compressed air. The second compressor receives the cold fraction discharge air and generates a supply of instrument air at a pressure not in excess of 25 p.s.i.g. and which has a dewpoint below the freezing temperature of water. A method for producing relatively dry, compressed instrument air is also disclosed.
