Abstract
This invention is directed to a novel semi-rigid enhanced area filter element that can be installed and used with new or existing bag-type filter housings. The invention specifically refers to the pleated and padded element (5) fitted closely within a retaining basket (4) inside of a bag-type pressure filter housing (1) to provide preferred inside-out flow passage from inlet (2) to outlet (3) but with greatly enhanced surface area, padded serialized inner filtration, extended filter life and increased particulate removal efficiencies. The element (5) is composed of a pleated and padded stack (18) bonded to a resilient flanged upper open end cap (8) and a solid bottom end cap (9). The element is economical to manufacture, can utilize many of the single and multi-layer filter membranes and impregnated membranes presently on the market, and is free of complicated parts and mechanisms. The element can also be efficiently used as an adsorbent and/or coalescent cartridge for complete versatility of fluid filtration or separation purposes.
