ABSTRACT:
A fluid filter comprising a housing, a filter element disposed in the housing and arranged to receive a flow of fluid to be filtered from an upstream side of the element to a downstream side thereof, a fluid inlet communicating with the interior of the housing and with the upstream side of the filter element, a fluid outlet communicating with the downstream side of the filter element, and piston apparatus operative in a regeneration mode for producing circulation of fluid generally simultaneously from the downstream side of the filter element to the upstream side thereof and from the upstream side of the filter element to the downstream side thereof, thereby dislodging and reorienting particulate matter engaging the filter element.
