  • Patent number: 9527027
    Abstract: 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.
    Type: Grant

  • Publication number: 20070256395
    Abstract: An air filter assembly for removing particulate matter from an incoming dirty air stream. The assembly includes a housing having an inlet, an outlet, a dirty air chamber and a clean air chamber and a non-cylindrical shaped elongated filter element arranged within the dirty air chamber constructed to remove particulate matter from an incoming air stream. A plurality of non-cylindrical filter elements are preferred. The non-cylindrical filter elements provide a decreased incoming air stream velocity when compared to conventional cylindrical filter elements having the same surface area. Alternately, the non-cylindrical filter elements allow an increase in the volume of incoming air when compared to conventional cylindrical filter elements having the same surface area.

  • Publication number: 20060112667
    Abstract: A method for cleaning a filter having Z-media includes providing a filter having Z-media and cleaning the media construction by directing a pulse of compressed gas into the media construction through the downstream flow face. Filter elements useable with such methods include elements made of Z-media. An example system utilizing the method includes a gas turbine air intake system.
