Air filter systems, filter bag assemblies, filter bags and corresponding methods are described herein. Air filter systems, filter bag assemblies, filter bags and corresponding methods are described herein. The filter bag assemblies include a flange assembly, a cage attached to the flange assembly, and a filter bag installed over the cage with an opening at the flange assembly. When installed in the dirty air chamber of the air filter system, a seal between the flange assembly and the tubesheet defining the dirty air chamber is provided by applying a seal force on the end of the filter bag assembly located proximate the access panel on the side of the dirty air chamber opposite the tubesheet. That seal force is transmitted to the flange assembly through the cage. The tubular filter bags may be in the form of triangular bags and/or may include bag support connectors at the closed end of the bag.

Air filter systems, filter bag assemblies, filter bags and methods

Z-filters capable of cleaning particulate matter from airflow streams in dust collectors, including reverse flow, reverse air, and reverse pulse systems.

Filter cartridge; components thereof; and methods

Filter bags, filter bag support assemblies, and filter bag assemblies are described herein. The filter bags, filter bag support assemblies, and filter bag assemblies may be used in air filter systems to remove particulate matter from air or other gases. Methods of using the air filter systems and methods of assembling the filter bag assemblies are also described.

Enlarged opening filter bags, support assemblies, and filter bag assemblies

Air filter systems, filter bag assemblies, filter bags and corresponding methods are described herein. The filter bag assemblies include a flange assembly, a cage attached to the flange assembly, and a filter bag installed over the cage with an opening at the flange assembly. When installed in the dirty air chamber of the air filter system, a seal between the flange assembly and the tubesheet defining the dirty air chamber is provided by applying a seal force on the end of the filter bag assembly located proximate the access panel on the side of the dirty air chamber opposite the tubesheet. That seal force is transmitted to the flange assembly through the cage. The tubular filter bags may be in the form of triangular bags and/or may include bag support connectors at the closed end of the bag.

An air filter cartridge includes a coiled media pack with inlet flutes and outlet flutes. The coiled media pack has first and second rounded ends with at least a first straight side and a second side. The coiled media pack has: (i) a length extending along a straight line from a center of the first rounded end to a center of the second rounded end; (ii) a first width between the first straight side and second side; the first width being perpendicular to the length; and (iii) a second width thereacross; the second width being perpendicular to the length. The first width is narrower than the second width.
