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.

A fuel water separator comprises a housing that defines an internal volume that receives a mixture. The fuel water separator further comprises a filter element that is positioned within the internal volume. The filter element comprises a first endplate and a second endplate that is located opposite the first endplate. The filter element further comprises a filter media that is coupled to the first endplate and the second endplate. The filter media is structured to separate a dispersed phase from a continuous phase of the mixture. The filter element further comprises a collection sump that is located below the first and second endplate and structured to receive the dispersed phase. The filter element further comprises a retention barrier disposed above the collection sump. The retention barrier comprises a drain opening structured to discharge the dispersed phase through the retention barrier into the collection sump.

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 μm 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 μm such that the geometric standard deviation of fiber diameter is less than 2.

Composite filter media with multiple fiber structures including nanofibers

A filter assembly includes a filter housing having a longitudinal axis, the filter housing divided into a first filter chamber and a second filter chamber, a first element bottom endplate, a second element top endplate, an intermediate endplate positioned along the longitudinal axis between the second element top endplate and the first element bottom endplate, a first filter element housed within the first filter chamber and comprising first filter media positioned between the first element bottom endplate and the intermediate endplate, and a second filter element housed within the second filter chamber and comprising second filter media positioned between the second element top endplate and the intermediate endplate.

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 &#x3bc;m, 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.

Gradient nanofiber filter media

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 &#x3bc;m, and fibers configured in a gradient such that ratio of the geometric mean diameter of fibers at the upstream face of the nanofiber layer to the geometric mean diameter of fibers at the downstream face of the nanofiber layer is about 1.1 to 2.8, preferably about 1.2 to 2.4.

A water sensor for a fuel filtration apparatus includes a main body with at least one electrical contact disposed proximate the first end of the main body. The electrical contact(s) is operatively connectable to an electronic control unit. Multiple sensor contacts are disposed proximate a second end of the main body. The sensor contacts are configured to detect multiple water levels and provide an output on each water level detected. The electrical contact is configured to send the output to an electronic control unit. The water level information provided by the water sensor can be tracked by a control device to determine if the fill rate of water meets an alarm value.

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 &#x3bc;m, and fibers configured in a gradient such that ratio of the geometric mean diameter of fibers at the upstream face of the nanofiber layer to the geometric mean diameter of fibers at the downstream face of the nanofiber layer is about 1.1 to 2.8, preferably about 1.2 to 2.4.

This disclosure describes a filtration system and method for removing soap from diesel fuel. The removal involves passing fuel through the filtration system. By removing soap, injector sticking and plugging can be reduced and for fuel already contaminated with soap, lubricity and/or corrosion inhibition functionality resulting from the conversion of carboxylic acid additives can be restored to metal carboxylates.
