摘要： Various example embodiments relate to an automatic drain system for use with a fluid water separator. The automatic drain system includes a liquid-in-fuel sensor. The liquid in-fuel sensor is configured to detect a liquid level in a water sump. The solenoid has an open state and a closed state. A control unit is configured to activate the solenoid in response to a signal from the liquid-in-fuel sensor. Activation of the solenoid causes the solenoid to go from the closed state to the open state. The automatic drain system is placed in a condition for allowing fluid flow through the automatic drain system from the water sump.

摘要： This disclosure generally relates to perforated filter media and coalescing filter elements utilizing perforated filter media. One example coalescing filter element is structured to separate a dispersed phase from a continuous phase of a mixture. The filter media includes a first coalescing layer. The first coalescing layer includes a first filter media. The first filter media has a plurality of pores and a first perforation. Each of the plurality of pores is smaller than the first perforation. The first perforation is formed in the first filter media and extends through the first filter media. The plurality of pores are structured to capture a portion of the dispersed phase. The first perforation is structured to facilitate the transmission of coalesced drops of the dispersed phase through the first coalescing layer such that the coalesced drops of the dispersed phase are separated from the portion of the dispersed phase captured in the first coalescing layer.

摘要： Disclosed is a composite filter media. The composite filter media is formed from multiple layers of media material including a nanofiber media layer, where the layers are laminated, bound, or otherwise composited to each other. The composite filter media can comprise at least one nanofiber layer comprising polymeric media material having a geometric mean fiber diameter of about 100 nm to 1 μm, and fibers configured in a gradient such that ratio of the geometric mean diameter of fibers at the upstream face of the nano fiber layer to the geometric mean diameter of fibers at the downstream face of the nano fiber layer is about 1.1 to 2.8, preferably about 1.2 to 2.4.

摘要： 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.

摘要： A filter media comprises a first fiber layer and a second fiber layer positioned downstream of the first fiber layer. The first fiber layer has a first geometric mean fiber diameter of less than 1 pm such that the geometric standard deviation of fiber diameter is greater than 2. The second fiber layer has a second geometric mean fiber diameter of less than 1 pm such that the geometric standard deviation of fiber diameter is less than 2.

摘要： Disclosed are filter assembly systems that utilize replaceable filter elements. The filter elements may include a ramp or sleeve for redirecting air intake when the filter elements are installed in the filter assembly systems and air is drawn into the systems. The filter elements and assembly systems may utilize co-acting components that mate with each other to at least one of: a) orient and permit mounting of the filter element in the systems; and b) permit mounting of only an authorized filter element in the systems.
