  • AIR FILTER ASSEMBLY HAVING NON-CYLINDRICAL FILTER ELEMENTS, FOR FILTERING AIR WITH PARTICULATE MATTER
    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.

  • Filter construction apparatus and method
    Patent number: 6368388
    Abstract: A filter construction allowing easy access to the filter is provided. The filter construction includes a yoke having a keeper, a filter supported by the yoke wherein the filter defines an opening, and a cover. The cover includes a plate for covering the opening in the filter, a tightening member connected to the plate and a catch for engaging the keeper on the yoke. An air filter assembly is also provided 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 first filter construction positioned in the dirty air chamber. A method of accessing an air filter in an air filter assembly is also provided.
