ABSTRACT:
A self-cleaning filter system is disclosed that includes an inlet fitting that is adapted to be inserted into an existing filter body. A spray tube having a plurality of outlets that slideably engages the inlet fitting, is positioned in the ring discs of the existing filter and a compression member proximate to one end of the ring discs applies a compressive force to the ring discs. When fluid enters the spray tube from the inlet fitting compression on the ring discs is reduced to allow the ring discs to separate while fluid pressure is simultaneously imposed on the ring discs through a plurality of outlets to clean the filter component. The parts included with the system may be used to convert a manual filter into a self-cleaning filter system.
