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 filter assembly includes a housing, a cover, and a filter element. The housing defines a pocket. The cover includes a bayonet sized to be received within the pocket. The bayonet defines an elongated opening. The filter element is sized to be received within the housing. The filter element includes a media pack and a filter shell coupled to the media pack. The filter shell includes a trunnion that is sized to be received within both the pocket and the elongated opening to interlock the cover and the filter element such that removal of the cover from the housing initiates removal of the filter element.

Various example embodiments relate to a filtration system and methods for the installation and use of such a filtration system. According to a set of embodiments, the filtration system comprises a housing that defines a central compartment therein. The filtration system further comprises a filter cartridge positioned within the central compartment of the housing. The filter cartridge comprises a filter media and an identification element. The filtration system further comprises a sensor. The sensor is structured to sense the identification element of the filter cartridge. The filtration system further comprises a filter blocking mechanism communicably coupled to the sensor. The filter blocking mechanism is structured prevent installation of the filter cartridge into the housing unless filter cartridge information of the identification element sensed by the sensor is identified as corresponding to an authorized filter cartridge.

Interlock for genuine filter recognition

A filter assembly includes a support fame, a filter media, and a conditioning device. The filter media is coupled to the support frame. The filter media has a dirty side that receives an air stream and a clean side that outputs the air stream after having been filtered by the filter media. The conditioning device is coupled to the support frame. The conditioning device is positioned downstream of the clean side of the filter media with respect to the air stream and directly contacts the clean side of the filter media.

Air flow conditioning device

Filtration systems having a tangential air cleaner having a coiled media filter element and a cyclonic pre-cleaner are described. An outer wall of the filter element acts as a pre-cleaner sleeve of the housing to generate a cyclonic flow of the intake air prior to the intake air being filtered by the filter element. The housing cover includes geometry that redirects the cyclonic low from a tangential path to an axial, straight-through flow directed through an inlet flow face of the filter element. Various embodiments of such filtration systems offer increased filter performance and capacity compared to similarly sized cylindrical pleated filter elements having a radial flow filtering path.
