Abstract: A filter element including a filter media, an end cap, and a baffle. The filter media is configured to be secured within a housing. The housing includes an inlet configured to accept a fluid for filtering and the filter media including a circumferential outer surface. The end cap is positioned at and coupled to one end of the filter media. The baffle is positioned relative to the filter media at a position such that, when the filter element is correctly installed within the housing, the baffle is proximate the inlet of the housing. The baffle extends around only a portion of the circumferential outer surface of the filter media in a radial direction.

Abstract: Fuel filtration systems having an automatic drain assembly for water that accumulates in the filter housing are described. The filtration system includes a filter media that is configured to remove particulate matter and dispersed water contained within the fuel. The water is drained to a drain reservoir within the filter housing where the water collects. When the water reaches a threshold level, a controller initiates a warning to the engine operator, such as a dashboard light, that instructs the operator to shut the engine off. When the engine is shut off, the collected water is drained through a valve of the automatic drain assembly. In some arrangements, the automatic drain assembly can be retrofitted to existing fuel filtration systems thereby reducing the cost of fitting the automatic drain assembly to existing internal combustion engines.

Abstract: A Rogowski coil in a sensor unit has voltage induced by a conductor surrounded by the Rogowski coil. The voltage is integrated to represent current which is converted to digital data representing current in the conductor and sent wirelessly to a multimeter. The sensor unit may receive control signals from the multimeter and a remote control apparatus. A plurality of sensor units may be networked and controlled by the remote control apparatus.

Abstract: Various embodiments relate to an air intake duct. The duct includes louvers forming an air inlet to a housing. Each louver includes an inlet section and an angled section, the angled section inclined with respect to the inlet section. The duct includes the housing positioned downstream of the louvers in an air flow direction. The housing includes a drain configured to permit separated water from an intake air passing through the louvers and into the housing to be drained from the housing. The duct includes an inner inlet duct that provides the intake air to a component. The inner inlet duct extends into the housing and positioned downstream of the louvers in the air flow direction. The inlet duct extends above the drain by a distance thereby forming a well in the housing between a top of the inner inlet duct and the drain.

Abstract: A filter element comprising a filter media and an outer surface. The filter media is formed in a closed loop, the closed loop defining a hollow interior extending along a longitudinal axis between a first end of the filter media and a second end of the filter media. The outer surface surrounds a perimeter of the filter element and is defined by a substantially circular first portion and at least one second portion. The first portion is substantially circular at a selected height of the filter media, and the at least one second portion is depressed relative to a circle defined by the substantially circular first portion at the selected height.

Abstract: A filter assembly includes a conditioning device that conditions a flow of air upstream of a mass air flow sensor. The filter assembly includes a support frame. The filter assembly further includes a filter media coupled to the support frame, the filter media having a dirty side configured to receive a stream of air and a clean side configured to output a stream of air that has been filtered through the filter media. The filter assembly includes a conditioning device coupled to the support frame, the conditioning device positioned in a downstream direction from the clean side of the filter media with respect to the stream of air, the conditioning device offset from the clean side of the filter media by a separation distance.

Abstract: Cleanable filters and methods of cleaning filters are described in the present application. The cleanable air filter includes a housing and a filter element installed in the housing. The filter element is configured to filter an operating fluid in a given application. The filter element is cleanable in-situ in the installed condition in the housing. The cleanable air filter further includes a cleaning fluid applicator configured to apply a cleaning fluid to the filter element while the filter element is in the installed condition in the housing such that the filter element is cleanable without being removed from the filter housing.

Abstract: A fluid filter assembly and a replaceable fluid filter cartridge are described where the fluid filter cartridge has an endplate that acts as a lid for the housing in which the fluid filter cartridge is installed. The endplate also includes a fluid flow passage formed therein through which filtered fluid exits or fluid to be filtered enters.

Abstract: A filter assembly, panel filter element, and servicing method is provided for reducing inlet flow restriction from a housing inlet into an inlet plenum and reducing outlet flow restriction from an outlet plenum to a housing outlet.

Abstract: A filter assembly for filtering fluids includes a housing having a base and a cover having guide structure for assembly. The guide structure may also provide gasket retention.

Abstract: A fuel heater module and a water-in-fuel sensor module are disclosed that are configured to be connected to an outside surface of a filter assembly. The fuel heater module includes an inlet port and an outlet port with a heating element positioned in the fluid path between the inlet and outlet. A thermostat is included for controlling operation of the heating element. The water-in-fuel sensor module is configured to detect water in the filter housing that it may be drained from the filter housing. Both modules are configured to be attached to an outside surface of the filter housing thereby being readily replaceable.
