Abstract: A filter element includes a tube of filter media, a first end cap and a second end cap. The tube of filter media extends between a first end and a second end. The tube of filter media has a cylindrical outer periphery and defines a central cavity. The first end cap is secured to the first end of the tube of filter media. The first end cap includes a first aperture having a first diameter. The second end cap is secured to the second end of the tube of filter media. The second end cap includes an attachment region adjacent the second end of the filter media and a first central hub positioned radially inward of the attachment region. The first central hub defines a second aperture having a second diameter. The second diameter is smaller than the first diameter. Systems having one or more filter elements, a tube sheet, and mounting yoke are provided.

Abstract: Filter elements, filter mounting systems, filter systems, methods of servicing filter systems, and methods of mounting filter elements are provided herein.
