FILTER ELEMENT AND FILTER ASSEMBLY FOR SEPARATING FLUIDS

摘要

A filter element may include a first end cap including an end cap barrier including an inner end cap aperture and end cap flow passages configured to provide flow communication between the of interior the filter element and the exterior of the filter element. The filter element may also include a first tubular member having a first end coupled to the first end cap to provide flow communication between the inner end cap aperture and a second end of the first tubular member. The filter element may further include first filter media extending around the first tubular member, an intermediate barrier coupled to a second end of the first tubular member, and second filter media having different filtering characteristics than the first filter media. One of the first filter media and the second filter media may include a coalescing-type media configured to promote separation of a first fluid from a second fluid.

1. A filter element having a longitudinal axis, the filter element comprising:
a first end cap including an end cap barrier including:
an inner end cap aperture configured to provide flow communication between an interior of the filter element and an exterior of the filter element; andend cap flow passages configured to provide flow communication between the interior of the filter element and the exterior of the filter element; a first tubular member having a first end coupled to the first end cap to provide flow communication between the inner end cap aperture and a second end of the first tubular member, wherein the first tubular member includes:
an inner tubular element including a tubular element first end and extending along the longitudinal axis to a tubular element second end, the tubular element first end being coupled to the first end cap and being configured to provide flow communication between the inner end cap aperture and the tubular element second end; andan outer tubular element coupled to the tubular element second end and extending coextensively along the inner tubular element to form a space between the inner tubular element and the outer tubular element, the outer tubular element including first tubular element apertures; first filter media extending around the outer tubular element; an intermediate barrier coupled to the second end of the first tubular member and including an intermediate barrier aperture; second filter media having different filtering characteristics than filtering characteristics of the first filter media, the second filter media including an inner passage and being coupled to the intermediate barrier opposite the first filter media and being in flow communication with the inner tubular element; and a second end cap coupled to the second filter media at an end opposite the intermediate barrier, wherein one of the first filter media and the second filter media includes a coalescing-type media configured to promote separation of a first fluid from a second fluid having different characteristics than the first fluid as a fluid including the first fluid and the second fluid passes through the one of the first filter media and the second filter media.
