Abstract
A filter assembly has a cylindrical filter element immersed in the fluid to be filtered, and which fluid normally flows radially inwards through the filter element and is thereby filtered. When the filter element is to be cleaned by backflushing, fluid flowing inwardly through the filter element is impelled by a rotating pump vane which directs fluid within the filter element outwardly at relatively high through the filter element thereby dislodging debris which may have adhered to the exterior of the filter element.
