Abstract: A filter apparatus (10) having a bag filter subassembly (14) for collecting contaminating material. The bag filter subassembly includes a bag filter (58) having a top end portion (66) and an integral collar (60). The collar has a lower portion (62) fixedly connected to the bag filter, and has a middle portion (68) to be supported within a vessel, and has a top lip portion (70) to engage a cover plate of the vessel. The collar has a pivotal web portion (78) disposed between the middle portion and the top lip portion, and has an inner surface with a groove having sidewalls, whereby internal pressure on the sidewalls pivot the top lip portion causing a sealing ring bearing area (82) on the cover plate (24).

Abstract: A filter apparatus having a filter bag subassembly (14) for collecting contaminating material is disclosed. The filter bag subassembly (14) includes five diametrically and axially-spaced bags (58, 98, 100, 102, 104) and an integral collar (60). The five spaced bags (58, 98, 100, 102, 104) form five spaced chambers (130, 132, 134, 136, 138) within cavity (20) and the integral collar (60) has a stepped shape forming five cylinder support portions (62, 90, 92, 94, 96) for the five spaced bags (58, 98, 100, 102, 104).

Abstract: Appareil de filtration (10) comprenant un sous-ensemble sac de filtration (14) destiné à recueillir une matière contaminée. Le sous-ensemble sac de filtration comporte un sac de filtration (58) présentant un partie d'extrémité supérieure (66) et un collier solidaire (60). Ledit collier comprend une partie inférieure (62) connectée fixe sur le sac de filtration, une partie intermédiaire (68) devant être supportée dans un récipient, et un rebord supérieur (70) qui vient en contact avec le couvercle du récipient. Le collier comprend une partie plate pivotante (78) située entre la partie intermédiaire et le rebord supérieur et une surface intérieure présentant une rainure ayant des parois latérales, ceci permettant à la pression interne s'exerçant sur les parois latérales de faire pivoter le rebord supérieur ce qui produit une surface de contact annulaire étanche (82) sur le couvercle (24).

The inlet of the wrapped cylindrical bag is optionally fitted with vortex directing means to enhance a linearly tangential direction of the entering liquid against the walls of the inside membrane. The invention also pertains to a method for the fabrication and use of the present filtration bag.
