ABSTRACT:
A filter assembly comprising a filter head having inlet and outlet ports; a filter bowl attached to the filter head, wherein the filter bowl has a drain hole located at the bottom of the filter bowl for draining fluids; a filter element housed within the filter bowl, the filter element including a barrier of filtration media, a drain layer and at least one support tube; wherein a pressure differential exists across the filter element; a bottom cap that seals fluid within the filter element; a top cap having a non-planar flange portion, wherein the flange portion has a substantially curving, generally s-shaped cross-sectional profile, the non-planar flange sealingly received within the filter head such that the filter head is divided into inlet and outlet partitions; wherein the top cap directs fluid from the inlet port into the filter element, where the fluid flows through the barrier of filtration media and then out of the assembly through the outlet port; and, a float drain component attached to the base of the filter bowl and aligned with the drain hole for controlling a condensed fluid level within the assembly.
