Abstract

A filter element for a compressed air filter includes a filter element (206) having an upper end cap (208) and a lower end (102), the upper end cap having a rim (230) extending and defining an outer perimeter of the upper end cap, the rim includes an outer slanted surface (234) which extends radially outward and upward. A filter body (204) is also provided and defines a cavity (258) and includes an open upper end (256) for receiving the filter element, the open upper end includes a ledge (264), wherein the ledge is slanted and extends radially inward and downward, defining a seat for matingly receiving the slanted surface of the rim of the upper end cap. A filter head (202) is provided and includes a filter element connector for coupling to a collar of the filter element, and a filter body connector for coupling to the filter body.

Description

technical field [0001] The present invention relates to filter elements for filters, and more particularly to filter elements and filter cups for compressed air filters. Background technique [0002] Existing technologies include general air treatment technologies such as compressed air filters, dust filters, general purpose filters, coalescing filters, and activated carbon filters. Compressed air filters may include a filter body containing a filter element coupled to a filter head. The filter head usually includes fittings for connecting the filter into the compressed air system. Filter elements require periodic replacement to maintain compressed air system performance. In particular, a standard schedule for filter element replacement significantly reduces pressure drop losses in compressed air systems. [0003] To accommodate the replacement of filter elements, the fittings for coupling to the compressed air system are generally limited to the filter head. The filter ...
