Abstract: A filter element has a pleated filter mat (3). The terminal axial ends (7, 8) of the mat are connected to end caps (9, 11). The mat has a main structural layer (15) having filtering properties and a first additional structural layer and a second additional structural layer (17,19). The surface area of each of the additional structural layers (17, 19) is smaller than the surface area of the main structural layer (15). The axial ends (12, 14) of one additional structural layer (17) is located at an axial distance from the axial ends (16, 18) of the other additional structural layer (19) on the filter mat (3).

Abstract: A filter cartridge having an endplate formed of polyurethane having a varying hardness is described. A first portion of the endplate is harder than a second portion of the endplate. The first portion of the endplate helps support the filter media of the filter element and maintain the shape of the filter element. The second, softer portion creates a seal between the filter element and a filter housing when the filter element is installed in the filter housing. The first portion and separate portions may be formed from different types of polyurethane or from the same type of polyurethane having a varying composition as a function of the radial distance of the endplate.

Abstract: An end member (3A) for a spiral separation membrane element includes: an inner annular portion (31); an outer annular portion (32) surrounding the inner annular portion (31) at a distance from the inner annular portion (31); a plurality of connecting portions (33) connecting the inner annular portion (31) and the outer annular portion (32); and a shield plate (34) disposed between at least one pair of the connecting portions (33) and forming an opening (41) between the shield plate (34) and the outer annular portion (32). According to this configuration, a radially outwardly spreading flow is formed by the shield plate (34), and therefore suspended solids in a feed liquid can be effectively directed to the peripheral region.

Abstract: A filtering device for fluids includes a filter housing (1) and a filter element (9) received in the filter housing. The filter element has an end cap (17) on at least one end. The end cap forms an enclosure for the corresponding end edge of the filtering material (23, 35) and is fixed on an element receiver (13) interacting with the bottom part (5) of the filter housing (1) to fix the position of the filter element (9) in its functional position. The element receiver forms a fluid path for the cleaned fluid exiting the hollow chamber (19) of the filter element (9). The element receiver (13) contains a valve arrangement (55) blocking the fluid path (35). A control device (79, 83) releasing the valve arrangement (55) in the functional position is on the end cap (17) of the filtering element (9). The end cap is fixed on the element receiver (13).

Abstract: A filter element is particularly suitable as a “green” filter element because all of its parts are flammable for disposal of after use by incineration. The filter element has an annular pleated filter media, hard resinous end seals and compressible gaskets bonded directly to the end seals. In accordance with one embodiment, both the end seals and gaskets are applied to the ends of the filter media by sequential steps in an injecting molding machine. In accordance with another embodiment, the gasket is molded to the end cap to form an integral assembly and the end cap is then fixed to the filter media by adhesive or by heat bonding.
