A method of manufacturing a media assembly comprises winding a filter media about a center axis into a media roll and cutting the media roll along at least two cut lines and into at least two media packs of at least two media assemblies. The media roll is cut along at least one plane that is parallel to the center axis.

Filter assemblies with unique shapes

A filtration system includes an air cleaner housing and a filter element. The air cleaner housing includes a base and a removable cover. At least one of the base or the cover defines a cavity and a protrusion extending into the cavity. The filter element is disposed within the cavity. The filter element includes a plurality of media blocks each including a pleated filter media. The plurality of media blocks are arranged in arch shapes of approximately equal inner radii. The plurality of media blocks are coupled to each other along opposing edges that extend along a pleat direction of the pleated filter media. The media blocks together define at least one void that extends along the protrusion. The protrusion occupies a portion of the void.

Arched air filter

A filter element includes a media pack and a support body. The media pack may be arranged in an enclosed shape defining a central cavity. The media pack includes a formed filter media and an abrasion resistant barrier coupled to the formed filter media. The support body is disposed within the central cavity. The abrasion resistant barrier separates the media pack from the support body. In some instances, the media pack also includes a plurality of adhesive beads disposed between the abrasion resistant barrier and the formed filter media and coupling the abrasion resistant barrier to the formed filter media.

Integrated abrasion resistant barrier for filter media

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

A run-safe filter system is provided for confirming installation of a qualified filter element in a housing. An electrical switch has a first electrical condition in response to a qualified filter element being installed in the housing, and a second electrical condition in response to the absence of a qualified filter element installed in the housing.

Run-safe filter system

Disclosed are methods and systems for monitoring and indicating the optimal replacement interval for a filter. In particular, the methods and systems may be utilized for monitoring and indicating the optimal replacement interval of an air filter in an internal combustion engine based on parameters that include air filter plugging rate data, engine duty cycle data, pressure drop across the air filter, penalty on fuel consumption, and the cost of air filter replacement.

Engine air filter replacement indication system

An exhaust aftertreatment system, including injection of chemical species, includes a mixer provided by a spiral chamber.

Exhaust aftertreatment system with spiral mixer

An apparatus, system, and method for measuring static pressure in a warm gas flow while minimizing particulate deposit formation includes a housing containing the flow of gas, a pressure sensor, and a heated pressure sampling tube attached to the sensor, with the tube sampling the gas flow. The heated sampling tube reduces the temperature gradient between the gas and the tube, reducing thermophoretic forces that contribute to deposit formation. The sampling tube extends through the housing into the gas flow in one embodiment, enabling the gas to heat the tube and locating the open end of the tube in a higher-flow area of the gas, further reducing deposit formation.
