Abstract
A filter assembly for use in filtering air in a dust collecting system has a pleated conical filter element which is mounted within a pleated cylindrical filter element. The cylindrical filter element is attached at one end to a base member and at the other end to a top member. The base portion of the conical element is attached to the base member. The apex of the conical member is closed off by a brace which has brackets thereon for supporting the conical member on the inner wall of the cylindrical member. Air to be cleaned is flowed into an aperture formed in the base portion and flows into the inner portion of the conical element with various portions of the air flowing through the filter walls of the conical element into the space between such walls and the cylindrical element. Air to be cleaned is also fed through the side portion of the cylindrical element into the space between the conical element and he cylindrical element with the filtered air being fed out through an aperture in the top member.
