Abstract

A filtering system comprises an outer housing into which fluid enters tangentially through a side inlet port to create rotational flow therein. Solid contaminants which clog filtering media are precipitated to the bottom of housing through action of centrifugal force in rotational flow. An inner can, disposed within the housing shrouds a filter cartridge. Unfiltered fluid flows rotationally into the inner can and is filtered through a vertical cylindrical filter cartridge. Filtered fluid flows up through the center of said cartridge to a clean fluid chamber below a domed cover and exists downwardly through a vertical outlet tube extending through the filter cartridge to an outlet port in the bottom of the housing. Gases in the system are collected in the clean fluid chamber and transported by the fluid flow through the outlet tube, thereby automatically purging gases from the filtering system.
