Abstract: A dual flow filter element includes inner and outer closed loop filter media and inlet and outlet end caps, and having a given sliape-in-shape configuration. A support frame extends axially from one of the end caps toward the other end cap and terminates a t a termination position between one-fourth and three-fourths of the axial distance between the inlet and outlet ends. Combinations using pleated filter media include a first group of pleat tip ends which are exposed, and a second group of pleat tip ends which are fully potted. One embodiment includes axiaily offset inner and outer closed loop filter media.
