ABSTRACT:
A filter for removing contaminants from compressed gas is disclosed. The filter features an inverse flow regime wherein gas entering the filter first flows downwardly and then reverses direction before encountering any filter media. The filter has a connection head with a gas inlet, a gas outlet and oppositely disposed openings separated by a central partition. The openings are sealingly enclosed by elongated tubular housings which releasably attach to the head. The gas inlet communicates with one side of the partition and the outlet communicates with the opposite side. A plurality of individual filter elements are arranged on either side of the partition and filter out aerosol, vapor and particulate contaminants from the compressed gas. The filter elements are releasably mounted to the central partition and can be removed and replaced independently of one another. The tubular housings are vertically oriented and a valve is provided in the bottom of the lower housing to drain accumulated liquid from the filter.
