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.

Abstract: A moisture removal device for compressed gas lines and the like includes a connection head having a gas inlet and a gas outlet. An elongated housing having an internal cavity is attached to the connection head with the use of a clamp ring. The elongated tube and head are sealed to each other with the aid of O-rings preventing the escape of the compressed gases. Internal of the housing is a cartridge containing desiccant media for the removal of water vapor from a compressed gas. The cartridge is sealed and supported to the connection head with the use of a centrally threaded rod and O-rings located between the cartridge and the connection head. The external body of the desiccant cartridge is impermeable to gas and forces compressed gas from the inlet of the connection head to the bottom of the elongated housing.

Abstract: A moisture removal device for compressed air lines and the like includes a connection head having a gas inlet and a gas outlet. An elongated housing having an internal cavity is threaded to the connection head and sealed thereto with O-rings such that a central distribution tube is coupled to one of the inlet and the outlet and an open end of the housing is coupled to the other. The housing contains desiccant material for removing moisture from the gas, held captive in the housing by a retention screen across the open end. The distribution tube is impermeable between its end coupled to the connection head and one or more openings at the opposite end of the housing. The gas thus flows from the gas inlet through the entire bed of desiccant material and is discharged through the gas outlet in the connection head.
