One embodiment relates to a filtration system. The filtration system includes a filter housing and a filter element. The filter housing defines a central cavity. The filter element is disposed within the central cavity. The filter element includes a first endcap, a second endcap, and filter media. The second endcap is disposed axially away from the first endcap. The filter media extends axially between the first endcap and the second endcap. The filter media includes a filter media surface. A support element is in contact with the filter media. The support element is conductive. A first pole is along a surface of support element the filter media. The first pole has a first charge. A second pole is downstream of the first pole. The second pole has a second charge. The first charge is opposite in charge to the second charge.

Various example embodiments relate to a filtration system and methods for the installation and use of such a filtration system. According to a set of embodiments, the filtration system comprises a housing that defines a central compartment therein. The filtration system further comprises a filter cartridge positioned within the central compartment of the housing. The filter cartridge comprises a filter media and an identification element. The filtration system further comprises a sensor. The sensor is structured to sense the identification element of the filter cartridge. The filtration system further comprises a filter blocking mechanism communicably coupled to the sensor. The filter blocking mechanism is structured prevent installation of the filter cartridge into the housing unless filter cartridge information of the identification element sensed by the sensor is identified as corresponding to an authorized filter cartridge.

The filter blocking mechanism is structured to prevent installation of the filter cartridge into the housing unless filter cartridge information of the identification element sensed by the sensor is identified as corresponding to an authorized filter cartridge.

A filter within a filter cartridge design is described that includes a sealing structure on an endplate of an outer filter element. Generally, the sealing structure includes an annular flange on the endplate that can directly seal against an interior surface of a housing when the filter cartridge is assembled for use. During filtration, the annular flange prevents a working fluid from bypassing the outer filter element. The sealing flange can seal with the housing in a press fit engagement.

Disclosed are modular filter-in-filter elements, namely an outer filter element and an inner filter element which may be assembled to form a filter cartridge for use in separation methods and systems. The outer filter element typically functions as a coalescing element and the inner element typically functions as a particulate filter element. The disclosed filter cartridges may be structured for separating water from a hydrocarbon-based liquid fuel as the fuel moves through the cartridge from outside to inside.

A dual stage filter includes an outer filter with a first media and an inner filter with a second media. A barrier is between the first media and the second media. The barrier directs fluid flow between the first and second media. The barrier creates a flow path between the first and second media, such that a working fluid, which is desired to pass through the first and second media, is directed by the barrier and flows through the second media, and such that another fluid, which is not desired to pass through the second media, is directed by the barrier and separates from the working fluid. Using the barrier, the dual stage filter can employ either or both upward flow and downward flow to achieve efficient fluid separation, for example fuel water separation in an engine fuel filter.

A fluid filter includes a filter element having a filtering media disposed between two endplates. One endplate includes an open flow passage that allows a working fluid to flow into or out of the media during operation. The other endplate includes a connection structure. A cover houses the filter element, and has an opening that is an inlet or outlet in fluid communication with the opening of the one endplate. The cover includes another fill opening proximate the other endplate. A cap is connected to the connection structure of the other endplate to close the opening of the cover. The cover is retained between the cap and other endplate. Generally, the attachment configuration between the cap and the other endplate of the filter element helps ensure that the filter element with the correct micron rating is installed in a filtration system.

A water separator and particulate filter with a first or outer stage configured to coalesce water from fluid such as fuel, and a second or inner stage configured to separate coalesced water from the fluid and also remove fine solid contaminants from the fluid. The coalescing stage includes a pleated cylinder of polymeric media. The pleated cylinder has pleat valleys and downstream pleat tips, and release sites defined at the downstream pleat tips. The separator stage includes a non-pleated cylinder of polymeric media surrounding and in contact with outer pleat tips of a multi-layer pleated cylinder.
