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