FILTER ASSEMBLY; COMPONENTS THEREFOR; AND, METHODS

摘要

Air filter assemblies and components therefor are described. The air filter assembly typically includes an air filter cartridge. Air filter cartridges including a media pack comprising at least a first stack of single facer strips are described. In examples described, at least a portion of the first stack of single facer strips is arcuate. Air filter assemblies are characterized that are configured, for example, to advantageously use such air filter cartridges. Example air filter assemblies are described that include pulse jet air cleaning systems.
