Abstract: The present invention relates to a novel filter element having a septum with a staged pleating that repeats a pleating sequence having a major (longest) pleat, a minor (shortest) pleat and at least one intermediate pleat therebetween. The intermediate pleat(s) have pleat heights that are evenly distributed within the range of pleat heights bounded by the pleat height of the minor pleat and the pleat height of the major pleat. In two particular embodiments of the invention, the pleat height ratios of the major, intermediate and minor pleats are 3:2:1 and 4:3:2:1. In an filter element, the pleated septum may be held between an inner core and an outer guard. The tip of the major pleat in each pleating sequence may be in contact with the inner core of the filter element. The septum may also include drainage layers on upstream and downstream of the filter material layer.

Abstract: A cartridge filter device having high filtration efficiency, having a long filter life, and capable of being produced at low cost. An out-in-pass-type pleated cartridge filter device has a filtration material, a core, a sleeve, and two end caps (upper and lower lid sections). In a filter material cross-section orthogonal to pleat folding, there are one mountain folding line (a), two valley folding lines (b) on both sides of the one mountain folding line, and two mountain folding lines (c) on both sides of the two valley folding lines. Thus the cartridge filter device includes a letter W-shaped section where there are one low mountain section on the sleeve side, two valley sections on the core side, on both sides of the one mountain section, and two high mountain sections on the sleeve side, on both sides of the two valley sections. ® KIPO & WIPO 2007
