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

A filter element includes first filter media, second filter media, a frame, and a seal member. The frame is coupled to the first filter media and the second filter media, the frame securing the first filter media and the second filter media into a V-shape. The seal member is attached to and extends from the frame. The seal member includes a U-shaped channel structured to receive a ridge of a housing when the filter element is installed in the housing. The seal member is structured to form a seal between the filter element and the housing when the filter element is installed in the housing.

Filter with interlocking housing interface

An external brace for a filter element is described. The brace is configured to wrap around an exterior of a filter element having a filter media pack. The brace helps to support the filter media pack during filtering operations by preventing outward flexing of the filter media pack caused by fluid flowing through the filter media. In some arrangements, the brace interfaces with a filtration system housing to provide additional support to the filter element.

External brace reinforcement structure for improved strength and performance of primary filter element

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.

Disclosed are sealing apparatuses having a sealing gland for an O-ring, the sealing gland comprising a primary gland and an auxiliary gland located below the primary gland. The apparatuses may be utilized for filter cartridges in filter systems.
