Abstract: A filter element includes a media pack of Z-media having first and second opposite flow faces and a side wall extending between the first and second flow face. A gasket is secured to the side wall. The gasket has a sealing portion and an attachment portion. The sealing portion has a flat surface at least one inch long and is located between being planar with and 0.5 inches recessed from the first flow face, inclusive. The filter element can be used in a dust collector.

Abstract: Filter cartridges including tubular filter media having ovate cross-sections and filter systems using the ovate tubular filter cartridges are described herein. The inner perimeters of the ovate cross-sections of one or more of the filter cartridges may be asymmetric, i.e., the inner perimeters of the cross-sections of the tubular filter media in the filter cartridges may have no lines about which they are symmetric. The inner perimeters of the ovate cross-sections of the tubular filter media in one or more of the filter cartridges may have only one line of symmetry

Abstract: The air filter systems described herein include one or more pulse collectors and pulse generators aligned along pulse axes. The pulse generators and filter elements may be arranged along a pulse distance as measured from a pulse outlet to a filter element opening. The pulse collectors and the filter elements may have openings with a relationship between them within parameters described herein. The pulse collectors may have a relationship between their hydraulic diameter and their length within parameters described herein. The pulse collectors may include a filter section and a pulse section that meet at a junction along a length of the pulse collector. The pulse sections may have a hydraulic diameter that increases when moving from the junction to the tube sheet opening of the pulse section. The filter sections may have a hydraulic diameter that remains constant when moving from the junction to the filter end opening of the filter section. Filter elements/cartridges used in the air filter systems may have filter media shaped or formed into ovate cross-sections
