Abstract
A filter element and assembly for fluid applications which require a purging of air, and particularly for applications where the filter element is horizontally oriented (side loaded), where the filter element is rotationally positioned relative to the housing such that a vent orifice is properly located for venting air from the filter element as the element fills with fluid. The housing includes a cylindrical body with a closed end a threaded open end, and a threaded, cup-shaped cover which is screwed down onto the housing. The filter element and housing include i) cooperating retaining devices which temporarily couple the filter element to the housing cover when the element is initially inserted into the housing and the cover is initially screwed onto the housing; and ii) cooperating orientation devices which rotationally orient the filter element in the housing as the housing cover is further and fully screwed down onto the housing.
