Abstract
A full flow fluid filter (300, FIG. 15) has a housing (302) extending axially along an axis (304), and a pleated filter element (318) having a plurality of pleats in a closed loop annulus having an outer perimeter (320) defined by a plurality of outer pleat tips, an inner perimeter (322) defined by a plurality of inner pleat tips, and a hollow interior (324) extending along the axis. Fluid flows substantially directly axially through the filter element, with minimal bending and change of direction, minimizing flow restriction.
