Abstract: A filtration assembly for a pressurized fluid system having a horizontally oriented tubular pressure vessel with a removable lid. A plurality of shroud tubes arranged in an inner array and a surrounding outer array receive contaminated fluid from the pressure vessel inlet through apertures in a vessel bulkhead to which the shroud tubes are attached. A plurality of tubular filter media elements with a closed end are received in each shroud tube and the opposite open end of each filter element is attached over an aperture in a cover plate sealed over the open end of the shroud tube. A tubular back wash arm has its opposite ends disposed for, upon rotation by a servo motor, being positioned progressively over selected apertures in the bulkhead for connecting the selected filter media elements to a drain for effecting backwashing.
