An air cooler and cleaner for cooling compressed-air coming from an air-compressor and for removing the moisture content thereof and for removing lubricant oil and solid particles and other contaminants which may be entrained therein. The air cooler and cleaner includes a tubular aluminum housing and an upper housing-closure and a lower housing-closure. Sheet-aluminum cooling fins having housing-receiving openings and cylindrical spacer and heat-conductor collars around said openings heat-shrunk onto the housing in firm thermally-conductive contact therewith and spacing the fins in relation to each other. A swirl-chamber in the lower portion of the housing and a cooling-chamber in the upper portion of the housing. The swirl-chamber has a tangential air-inlet for rapidly spinning the air therein. An inverted cylindrical cup-like air-director within the cooling-chamber for directing the air against and along the wall of the cooling-chamber in a thin layer. A funnel-like member including a flange a short distance below the air-director for separating the swirl-chamber from the cooling-chamber and having a central opening and an air-riser-tube extending down from said opening into the swirl-chamber to a substantial depth thereof. An air-outlet port in the upper closure for the discharge of the cooled and cleaned air. A filter in the upper end of the tubular housing, through which the compressed-air passes. A contaminant drain-opening in the swirl-chamber and an automatic drain-valve connected with the drain opening.

An air cooler and cleaner for operative mounting in a compressed-air pipe-line between an air-compressor and its compressed-air storage-reservoir, for cooling the compressed-air and for removing therefrom any moisture, lubricating-oil and solid particles which may be entrained therein, said air cooler and cleaner including a cooling-chamber, an unbaffled swirl-chamber adjacent the upstream end of the cooling-chamber, a compressed-air inlet arranged to be connected with the discharge outlet of an air-compressor and communicating with said swirl-chamber in a zone thereof substantially nearer the cooling-chamber than the opposite end thereof and arranged to deliver the compressed-air from the compressor into the swirl-chamber generally tangentially with respect thereto and to freely swirl the compressed-air in the swirl-chamber without baffled interruption, to separate therefrom liquid and solid particles entrained therein, a contaminant-drain-opening forming an exit from said swirl-chamber, and the lower portion of said swirl-chamber being pitched downwardly towards said drain-opening, a member positioned between and separating the cooling-chamber and the swirl-chamber and separating its tangential air-inlet from the cooling-chamber, said member having a hole therethrough, an air-exit tube carried by said member and communicating with and extending from the hole therein into the swirl-chamber a substantial distance beyond its tangential air-inlet, and spaced from said swirl-chamber exit thereby to cause the swirling motion of the compressed-air to extend a substantial distance axially into the swirl-chamber before the compressed-air passes from the swirl-chamber into the cooling-chamber, an automatic drain-valve operatively connected with said drain-opening and having a control-port and arranged to be controlled by a pilot-fluid under pressure from the compressor and arranged to have its control-port connected with the pilot-fluid output-port of the compressor, an air-outlet-port communicating with the downstream side of said cooling-chamber, said swirl-chamber and said cooling-chamber being so arranged with respect to each other that the compressed-air will flow from the swirl-chamber into and through the cooling-chamber, and a check-valve connected with said air-outlet-port for barring the flow of the compressed-air from the storage-reservoir into the cooling-chamber.
