ABSTRACT:
A self-cleaning fluid filter for filtering fluid entering an inlet of a pump, such as an air pump, in which a fluid filter is wrapped around a filter spool forming a filter drum and the drum coupled to the shaft of the pump motor for rotation thereof. The fluid entering the rotating filter will then be filtered of its impurities which, due to centrifugal force, will be dispersed outwardly from the filter drum to drop into a residue container. A deflector plate is disposed in proximity to the inlet for deflecting heavy particles to the residue container.
