Abstract

A pleated fluid filter element for removing particulate matter from a fluid stream that comprises a pleated filter media provided with a plurality of pleats having peaks and valleys and having a clean and dirty side. The pleated filter media further has arrays of elongated embossments projecting from both the clean and dirty sides thereof. The arrays of the elongated embossments are positioned so that the elongated embossments embossed on adjacent pleats of the filter media are offset from each other in a direction parallel to the peaks and valleys. The elongated embossments are provided for maintaining gaps between the pleats and spaces within the pleats and for channeling fluid into and out of the filter media.

a portion of one of said plurality of elongated embossments, and

a portion of one of said plurality of unembossed portions.

9. The filter element according to claim 4 , wherein one of the asymmetrical gaps includes

a surface segment of the first panel including

a portion of two of said plurality of elongated embossments, and

a portion of two of said plurality of unembossed portions; and

a surface segment of the second panel including

a portion of two of said plurality of elongated embossments, and

a portion of two of said plurality of unembossed portions.

10. A filter element, comprising:

a pleated filter media including a first end panel, a second end panel, and one or more intermediate panels between the first and second end panels, wherein each of the first end panel, the second end panel, and the one or more intermediate panels include a first side and a second side opposite the first side, a plurality of elongated embossments that extend outwardly from each of the first side and the second side; and a plurality of unembossed portions between each elongated embossment, wherein said plurality of elongated embossments of said one or more intermediate panels abut said unembossed portions of said first and second end panels to define said pleated filter media to include at least three or more successive panels that adjacently contact one another, wherein said one or more intermediate panels includes at least two intermediate panels, wherein an elongated embossment of each of the at least two intermediate panels abut an unembossed portion of the other of the at least two intermediate panels, wherein the abutting relationship of the first or second end panel and one of said one or more intermediate panels, or, the abutting relationship of said at least two intermediate panels defines two or more gaps therebetween, wherein the two or more gaps are asymmetrical according to an axis of symmetry extending through each of said plurality of elongated embossments.

11. The filter element according to claim 10 , wherein the plurality of elongated embossments extend from the first and second sides in an oscillating pattern.

12. A filter element, comprising:

a pleated filter media including a plurality of pleats, wherein each pleat of the plurality of pleats includes
