ABSTRACT:
A filter assembly having a replaceable coalescing filter in which contaminants are separated from fuel, oil, or the like. The filter assembly has an outer housing that may be constructed from a cylindrical metal container and a top metal plate. A filter element is attached in a cantilever manner to the metal plate, by chemical bonding and/or mechanical locking, solely by way of an support member. The filter element is thus suspended from the plate leaving a clearance space between the bottom filter cap and the bottom of the filter container. No elements are disposed in the clearance space, thus maximizing the efficiency of the filter. The support member may be made of rubber or similar material suitable for sealing the inner and outer fuel chambers and for chemically bonding to the metal housing. The upper end cap of the filter element also may be chemically bonded to the element support. As an alternative, the support member may be a metal or plastic screw lock that engages threads on both the metal plate and the upper end cap of the filter element.
