A filter, comprising: a filter element comprising pleated filter media having a plurality of pleats configured into a closed loop of filter media, the filter element having an outer perimeter defined by a plurality of outer pleat tips, and an inner perimeter defined by a plurality of inner pleat tips, the plurality of inner pleat tips defining an inner chamber extending through the filter element; a cap disposed on a first end of the filter element the cap being configured to seal a first opening of the first end of the filter; a first plurality of open end pleats positioned between an edge of the cap and the outer perimeter of the filter element, the first plurality of open end pleats defining a first fluid path through the filter media into the inner chamber; a sealing ring disposed on a second end of the filter element the sealing ring being configured to provide an inlet opening providing fluid communication to the inner chamber; and a second plurality of open end pleats positioned between an edge of the sealing ring and the outer perimeter of the filter element, the second plurality of open end pleats defining a second fluid path through the filter media into the inner chamber.

Radial seal filter with open end pleats

A filter assembly is disclosed herein the filter assembly comprising: a plurality of stackable elements each comprising a frame defining a perimeter surrounding a filter media disposed within the frame, the filter media being configured for use as a diesel particulate filter and capable of being regenerated at a temperature greater than 350 degrees Celsius, each frame being configured to have either a first feature on a first surface of the frame or a second feature on a second surface of the frame or both a first feature on a first surface of the frame and a second feature on a second surface of the frame, the first feature being configured to mate with the second feature; and the first surface of each of the plurality of stackable elements further comprises an inlet opening on one end of the frame configured to align with an inlet opening on the second surface of each of the plurality of stackable elements such that a plurality of openings are defined on only one side of the filter assembly, the plurality of openings providing fluid communication to the filter media.

Diesel particulate filter assembly

A filter assembly is configured to be incorporated into an exhaust treatment device. The filter assembly comprises a frame, a filter media element, and a plurality of dividers supporting the filter media element within the frame. The frame has a first end and a second end defining a frame length therebetween. The filter media element is disposed within the frame and extends generally perpendicular to the frame length as a series of pleated contours. The plurality of dividers includes a first divider and a second divider. The first divider is disposed adjacent to the filter media element at the first end of the frame. The second divider is disposed adjacent to the filter media element at the second end of the frame.
