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.

Perforated layer coalescer

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 monitor system ('FMS') module is installed on the engine/vehicle and is connected to the filter systems, sensors and devices to monitor various performance parameters. The module also connects to the engine control module (“ECM”) and draws parameters from the ECM. The FMS module is capable of interfacing with various output devices such as a smartphone application, a display monitor, an OEM telematics system or a service technician's tool on a computer. The FMS module consists of hardware and software algorithms which constantly monitor filter systems and provide information to the end-user. FMS module provides necessary inputs and outputs for electronic sensors and devices.

Electronic filter detection feature for liquid filtration systems

Various example embodiments relate to a system that includes a nozzle. A dosing line is connected to the nozzle and a fuel dosing module. The fuel dosing module is in fluid communication with the dosing line and includes an outlet in fluid communication with the dosing line. An air inlet is positioned upstream of the outlet and is configured to receive air. A fuel inlet is positioned upstream of the outlet and is configured to receive fuel. A fuel valve is positioned upstream of the outlet and downstream of the fuel inlet and is configured to control the flow of fuel. The fuel dosing module is configured to combine the fuel and the air upstream of the outlet and downstream of the fuel valve to generate an air-fuel fluid, wherein the air-fuel fluid removes particles from the nozzle.

Diesel fuel dosing module for regeneration of diesel particulate filters with continuous purging

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.

A filter monitor system ('FMS') module is installed on the engine/vehicle and is connected to the filter systems, sensors and devices to monitor various performance parameters. The module also connects to the engine control module ('ECM') and draws parameters from the ECM. The FMS module is capable of interfacing with various output devices such as a smartphone application, a display monitor, an OEM telematics system or a service technician's tool on a computer.

FMS module provides necessary inputs and outputs for electronic sensors and devices.

Filter media and media packs that provide robust performance in high-speed rotating coalescer (HSRC) elements for crankcase ventilation systems are described. The fiber media is HSRC fiber media. As such, the filter media has a higher resistance to compressibility then traditional coalescer filter media, such as fiber media used in low-speed rotating coalescer arrangements or stationary coalescer arrangements.

High speed rotating crankcase ventilation filter media and media pack

Disclosed here is a composite filter media having at least one nanofiber layer bonded to a substrate layer, the at least one nanofiber layer optionally having a plurality of nanofibers having a geometric mean diameter of less than or equal to 0.5 &#x3bc;m, the at least one nanofiber layer having a thickness of about 1-100 &#x3bc;m.

Nanofiber filter media for high performance applications

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.

Gas/liquid coalescing filter auto drain

Filtration systems having a normal filtration mode and an enhanced filtration mode are described. In some arrangements, the filtration system is an air filtration system having a primary air filter element, a pre-cleaner, and a pre-cleaner bypass valve. Based on feedback from an intake air quality sensor the bypass valve is either opened or closed to selectively route intake air through the pre-cleaner during sensed dirty air operating conditions (e.g., heavy dust or moisture concentrations). In other arrangements, the filtration system is a liquid filtration system (e.g., a fuel or oil filtration system) that has a main filter and a secondary filter. The filtration system selectively routes the liquid being filtered through the main filter, the secondary filter, or a combination thereof depending on a detected event or sensed characteristic of the liquid.
