A pleated media pack includes a section of media configured into a tube defining an interior volume and an open opening at one end. A ratio of the pleat depth to a diameter of the opening is greater than 0.2. At least some of the pleats at one end of the media pack are inverted. In some examples, the pleats include major pleats alternating with minor pleats.

Self-supporting folded sheet material, filter elements, and methods

A filter for use with bulk filtration includes filters arranged in parallel flow and a manifold arrangement. The manifold arrangement has a first pipe within a second pipe. An inlet channel conveys unfiltered fluid to the filters, and an outlet channel conveys filtered fluid from the filters. The inlet channel is an interior volume between an outside surface of the first pipe and an inside surface of the second pipe. The outlet channel is an interior volume of the first pipe. Methods of servicing and filtering are provided.
