Patent ID: 8349173

Claim:
A replaceable inside out flow filter element ( 10 ) comprising: an annular filter media structure ( 20 ); an upper end cap ( 30 ) attached to an upper end of the annular filter media structure ( 20 ), the upper end cap ( 30 ) including a support member ( 32 ) configured to engage associated structure on a filter assembly to support the filter element, and including a center opening ( 36 ) configured to allow inflow of industrial fluid to the radial inner side of the annular filter media structure ( 20 ) there through; a lower end cap ( 40 ) attached to a lower end of the annular filter media structure ( 20 ) opposed from the upper end cap ( 30 ), an inner annular bypass mounting sidewall ( 42 ) formed on the lower end cap ( 40 ), wherein the inner annular bypass mounting sidewall ( 42 ) is spaced in a radial inward direction from the radial inner side of the media structure ( 20 ); a bypass valve assembly ( 50 ) secured to the inner annular bypass mounting sidewall ( 42 ) of the lower end cap ( 40 ) and configured to communicate with the radial inner side of the annular filter media structure ( 20 ); and an imperforate annular bypass shield tube ( 60 ) coupled to the bypass mounting sidewall ( 42 ) having a first end adjacent the bypass valve assembly ( 50 ) and extending above and away from the bypass valve assembly ( 50 ) toward the upper end cap ( 30 ) to a second end of the bypass shield tube ( 60 ), wherein the annular bypass shield tube ( 60 ) is spaced in a radial inward direction from the radial inner side of the media structure ( 20 ).
