摘要： A pair of U-shaped housing members are oppositely disposed with leg portions of one member telescopically received between leg portions of the other member to form a housing. An inlet is formed in one housing member and an outlet is formed in the other housing member. Cup-shaped end walls engage and embrace opposite end edges of the housing. A pleated filter is positioned in the housing with its opposite end pleats, and a seal positioned adjacent each thereof, disposed between adjacent telescoped leg portions. An adhesive material partially fills each of the cupshaped end walls and has an adjacent portion of the pleated filter and an adjacent end edge of the housing embedded therein. The adhesive material cooperates with the seals between the leg portions to secure and seal the pleated filter in the housing to provide a filtering medium between the inlet and outlet and bond the filter assembly into an integral unit.

摘要： An air cleaner assembly includes a housing and a removable cover. A filter element is removably positioned in the housing. A two-part mating catch assembly includes a first part that is secured to the cover and a second part that is on one of the housing and the filter element. The first part and second part are positioned to releasably mate when the filter element is operably mounted within the housing.

摘要： A roll forming method may be used to provide a pleated filter media pack and filter cartridges with channels formed. The pack includes a strip of a filter media extending opposed edges and opposed front and back sides. The strip is pleat tips with spacer structure such as integrally formed embossments maintaining a spacing between pleat panels. The inlet and outlet flow faces are created by the edges of the filter media rather than the pleat tips. Alternating pairs of pleat panels are closed such as by seal beads at the inlet and outlet flow faces.

摘要： A filter element has a sheet of filter media having a first elongate edge and a second elongate edge. The sheet of filter media defines a plurality of pleats, a first set of pleat folds and a second set of pleat folds, where each of the plurality of pleats extend between the first set of pleat folds and the second set of pleat folds. The first set of pleat folds each extend from the first elongate edge to the second elongate edge, and the second set of pleat folds each extend from the first elongate edge to the second elongate edge. Each of the plurality of pleats defines a repeating wave pattern of flute peaks and flute valleys alternating from the first set of pleat folds to the second set of pleat folds. Each of the flute peaks and flute valleys extend from the first elongate edge to the second elongate edge.
