Abstract: A filter element has a ring of a first filter medium disposed between upper and lower end caps. A center tube extends between the upper and lower end caps radially inwards of the first filter medium. Holes in the center tube, adjacent the upper end cap, allow fluid to pass through the center tube towards a separator tube. The separator tube contains a second filter medium that strips water from the fluid into a fluid reservoir below the lower end cap. A radially offset duct defining a fluid passage extends from below the lower end cap to above the upper end cap.

Abstract: A filter assembly is provided that includes an immobilized base material in combination with a slow release mechanism for introducing an additive base material into a lubrication fluid flowing through the filter assembly. The introduced base material is a weaker base material than the base material of the immobilized base material. The combination of the immobilized base material and the additive base material provides a system that would work to neutralize acids for all lube formulations commonly used in the field. As a result, oil drain intervals can be extended.

Abstract: The present invention provides a filter apparatus for use in removing impurities and acids contained in a fluid that includes a particulate filter and an acid-neutralizing filter. Preferably, the particulate filter and the acid-neutralizing filter are positioned within a housing. A conduit having a pressure reduction section is arranged to create a pressure differential across the acid-neutralizing filter such that a portion of the fluid to be filtered by the filter apparatus passes through the acid-neutralizing filter.

Abstract: An environmentally friendly acid neutralizing filter cartridge for mounting into a chamber of a cartridge mounting body for neutralizing acid in engine oil in an oil circulation circuit of an engine. The environmentally friendly acid neutralizing filter cartridge comprises a support housing comprising substantially no metal parts such that the environmentally friendly acid neutralizing filter cartridge can be readily incinerated. The support housing comprises at least one inlet port and at least one outlet port. A bed of acid neutralizing particles is contained in the support housing between the inlet port and the outlet port. Means is provided for preventing acid neutralizing particles from flowing through the at least one outlet port. An annular seal is arranged externally on the support housing and separates the at least one inlet port and the at least one outlet port to prevent oil from short circuiting the bed of acid neutralizing particles.

Abstract: A filter cartridge which is environmentally friendly in that it is made up of components which are all incinerateable. The ends of a filter element are sealed using potting compound and plastic endcaps. The upper endcap, which is closed, has a pressure relief aperture associated therewith to prevent bowing. In a plugged filter condition the high downward pressure introduced on the upper endcap is compensated by providing the cartridge with centering ribs which bottom on an associated ledge in the housing to provide a positive stop for the top endcap, preventing it from being driven down into and through the filter element. Rubber gaskets are associated with the respective endcaps, and are reliably secured to the endcaps by being snap fit into grooves molded into the plastic of the endcaps. The lower endcap utilizes a simple radial seal gasket which is both highly effective and also positioned to avoid structural crushing forces on the cartridge. A keying system prevents the installation of improper filters.

Abstract: A filter system in which a housing and an environmentally friendly filter cartridge are coordinated to provide ease of change of the filter cartridge and reliable operation. The cartridge contains no metal parts and is readily incinerateable. The housing is provided with a number of “universality” features including a changeable bottom which allows the housing to operate as a fuel filter, a lubrication filter, or a hydraulic filter in different applications. The housing and cartridge are configured to provide support for the plastic elements of the cartridge to prevent crushing of the filter under normal and abnormal filter operating conditions. A key system associated with the cartridge and the housing provides assurance that the correct filter is installed for a particular application.
