Abstract: A method and apparatus for removing oil and water contaminants from chloro-fluoro carbon refrigerants. This system is a single pass filtration system specifically designed for sealed systems with no atmospheric bleed off of chloro-fluoro carbons. This system incorporates a novel oil absorbent and is compact enough for small commercial applications, such as service stations or portable service of environmental control units. This system also incorporates a new cartridge type filter containing both water and oil and particulate absorbtion and removal means.
