Abstract
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.
