Abstract
A filter cartridge for use in a fluid filtering system, constructed to induce rotational flow in the unfiltered fluid, includes a pleated filter sleeve in which the individual sleeves are slanted relative to the sleeve circumference in a direction opposite to the direction of the rotational flow fluid. The slanted pleats can be constructed by creasing a sheet of filter media at alternatingly shorter and longer widths to form pleats having relatively shorter front legs and relatively longer back legs. The shorter front legs bias the pleats in the counter-rotational direction.
