Abstract: Spacers for filtration membranes that are formed from perforated films. The spacer include unperforated regions, which can serve as integrated lamination strips, advantageously omitting the need for separate lamination steps required with woven and nonwoven spacer fabrics while also providing a spacer with a uniform thickness.

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 arrangement for threadably securing to a filter head includes a housing having a surrounding wall defining an interior volume, an open mouth providing access to the interior volume and an end opposite of the open mouth. The surrounding wall has an exterior and an interior. A filter media construction is operably held within the interior volume. A sleeve, distinct from the housing, is secured to the exterior of the surrounding wall adjacent to the housing mouth and extending partially along the surrounding wall. The sleeve has an exterior and an interior. The exterior of the sleeve defines mounting threads constructed and arranged to removably mount with the filter head, when the filter arrangement is secured to the filter head. The interior of the sleeve is against the exterior of the surrounding wall. A first seal member is oriented against the sleeve to create a seal with a filter head, when the filter arrangement is secured to the filter head. A filter assembly includes a filter arrangement and a filter head. The filter arrangement is removably secured to the filter head by a threaded connection between the sleeve and the filter head. A system includes an engine utilizing a liquid and a filter assembly in fluid communication with the engine to filter the liquid. Methods of making filter arrangements include utilizing structures characterized above.

Abstract: Pleated filtration media, filtration media packs, and filtration elements containing projections are disclosed. The pleated filtration media includes projections on at least one surface, the projections configured to engage adjacent media sheets so as to reduce masking of the media. The pleated media and media pleat packs contain protrusions on the surface of the media. These protrusions are three dimensional structures that are on the surface of the media and are provided by forming the protrusion directly in the filtration media or applying structures, such as adhesive beads, or onto one or both faces of the media. Elongation of the adhesive bead can facilitate greater separation of the adjacent faces of pleated media if desired. These protrusions, also referred to herein as projections or dimples, can either contact each other or contact flat media and keep adjacent media faces from becoming in intimate contact with each other.

Abstract: The present invention relates to filters used to remove debris from water being sucked into a piping system. It has particular application for use in nuclear power plants, which, after a loss of coolant accident, must pump cooling water back into the reactor core from a collection sump. This water may contain various types of debris that must be removed before the water is sent back into the reactor cooling system. Filtering of the debris is realized with the component known as “strainers”. There are restrictions on the space available for installing strainers. The vaned filtering element, for example a vaned fin, of the present invention is designed to reduce the space required for strainer installation by increasing strainer surface area per unit volume, while maximizing the quantity of debris that can be filtered from the water.

Abstract: A filter element has a zigzag-folded filter medium. Filter medium sections joined by a fold edge define an intermediate fold space, respectively, with a fold base and fold peaks opposite the fold base. An elongate support section is arranged in the intermediate fold space on a filter medium surface of one of the filter medium sections. The support section extends perpendicular to the fold edges between fold base and fold peak. The support section has a height extension perpendicular to the filter medium surface that increases in longitudinal direction of the support section from fold base to fold peak. The support section has a free side facing away from the filter medium surface. The support section has a width extension parallel to the fold edges. The width extension decreases parallel to the filter medium surface and perpendicular to the longitudinal direction from fold peak to fold base.

Abstract: An air filter may include a bellows made of an air-permeable filter medium, which is folded in a longitudinal direction to form a plurality of folds, for filtering air, and a supporting frame for supporting the bellows. The supporting frame may be a substantially closed comb-like ring having a plurality of supporting teeth. At least two supporting teeth adjacent in the longitudinal direction may fix at least two folds of the bellows also adjacent in the longitudinal direction to a predefined distance from each other. The comb-like ring may include two fold blades and two outer bands connecting the fold blades. The fold blades may be inserted in a transverse direction running transversely to the longitudinal direction into respective end folds of the bellows. The two outer bands may have the supporting teeth, including high supporting teeth and low supporting teeth.

Abstract: A connecting element (1) for connecting at least two end portions (2A, 3A) of a flat filter medium (2, 3) has at least three legs (1A, 1B, 1C), one end portion (2A, 2B) each being introducible between two legs (1A, 1B, 1C). Under the influence of heat it is possible to connect the material of the legs with the material of the filter medium (2). The connecting element (1) can be used in a filter element (4) and in particular in a filtering device (5), for example an operating fluid filter for a motor vehicle. The object of a method for connecting at least two end portions (2A, 3A) of a flat filter medium (2, 3) is that the end portions (2A, 3A) are introduced between two legs (1A, 1B, 1C) each of a corresponding connecting element (1) and that through heating the material of the legs is connected with the material of the filter medium (1).
