Abstract:
A replaceable inside out flow filter element comprises an annular filter media structure; an upper end cap attached one end of the media structure; a lower end cap attached to an opposed end of the media structure, with an inner annular bypass mounting sidewall formed on the lower end cap; a bypass valve assembly secured to the inner annular bypass mounting sidewall and configured to communicate with the radial inner side of the annular filter media structure; and an annular bypass shield tube coupled to the bypass mounting sidewall and extending above the bypass valve assembly toward the upper end cap, wherein the inner annular bypass mounting sidewall and the annular bypass shield tube combine with the radial inner side of the media structure to define an annular particulate receiving area that extends about at least ½ of the length of the media structure from the lower end cap.
