摘要： 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.

摘要： 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.

摘要： An embossed air filter filtration medium has at least one porous film and a plurality of air-permeable support materials supporting the at least one porous film. The least one porous film includes a fibril-formable polytetrafluoroethylene, a non-fibril-forming and non-hot-melt-processable component, and a non-fibril-forming and hot-melt-processable component having a melting point below 320° C. Surfaces of both sides of the air filter filtration medium are formed by two air-permeable support materials of the air-permeable support materials. The air filter filtration medium has a plurality of embossed projections. The embossed air filter filtration medium may be part of a filter pack, which may be part of an air filter unit. The embossed air filter filtration medium is manufactured by laminating air-permeable support materials on the at least one porous film and embossing the air filter filtration medium to form the projections.

摘要： An air filter unit has a pleated filter medium with a zigzag shape in which a fibrous filter medium has been folded multiple times. The coefficients of linear expansion of the space-supporting members provided in each of the multiple folded spaces of the pleated filter medium are equal to or greater than the coefficient of linear expansion of the metal filter frame of the filter unit. The linear expansion coefficients of first space-supporting members are smaller than the linear expansion coefficient of a second space-supporting member. The first space-supporting members are provided in side portion regions including both side portions positioned at outermost sides of the pleated filter medium in a second direction perpendicular to the first direction. The second space-supporting member is provided in a central portion region sandwiched between the side portion regions.
