摘要： A filter has a longitudinal axis with an inner diameter defined by a hollow longitudinally extending center. The filter has fingers extend radially outwardly arcuately from the longitudinal axis. The fingers have base ends near the longitudinal axis and outer edges at extremities spaced from the longitudinal axis. The outer diameter of the filter is defined by the outer edges of the fingers. The filter is formed from a sintered porous molded thermoplastic or another material resulting in a filter more rigid than standard filters. The fingers are spaced apart from one another a predetermined, substantially fixed distance to form slots therebetween sized to capture contaminants therein.

摘要： 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.

摘要： The invention relates to a filter medium in the form of a wound filter with a number of adjacent tubular flow channels (5, 6) with a radial flow, which are formed from a double-layered filter web material of which one layer has a smooth embodiment and the other is corrugated. The aim of the invention is to provide the above with a simple and hence economically-produced seal, by means of which the above may repeatedly be exchangeably inserted in a filter device with a seal with little complexity. Alternatively and optionally additionally the end regions for sealing of the filter web material which forms the wound filter should permit a simplified and reliable sealing. The above is achieved by means of a material characterised in that felt is provided on the external circumference of the wound filter as sealing material for a radial seal within a housing. Furthermore, the amplitude of the corrugations of the corrugated layer of the filter web material in the circumferentially terminating end regions can be embodied to taper gently towards the end and are produced accordingly.

摘要： A filter element according to the present disclosure includes a plurality of longitudinally extending pleats including outwardly radiating primary pleats and inwardly radiating secondary pleats, with at least one secondary pleat positioned between two adjacent primary pleats. Each primary pleat has a predetermined radial height, and each secondary pleat has a radial height that is less than the radial height of each primary pleat and different from the radial height of at least one other secondary pleat. A filter element according to the present disclosure provides greater filter area, an increased overall filter density, and access to more radial flow paths at the outer diameter of the filter element.
