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.
