Patent number: 6726735Abstract: A filter cartridge having a unitary construction with a pleat pack filter formed securely about an interior screen for installation in the tube sheet of a baghouse. Opposite ends of the pleat pack are integrally received within a bottom end cap and an upper fitting. The bottom end cap may be molded to follow the contour of the pleat pack, or may be molded as a disk with an inwardly projecting groove to centrally align the pleat pack therein. The upper fitting is formed of a resiliently flexible material and includes an upper flange to overlie and seal with the upper surface of the tube sheet, a tube sheet mouth insert to seal with a circular opening in the tube sheet, a contoured transition to seal with the lower surface of the tube sheet, and a lower cylindrical collar which permanently secures the upper end of the filter. The contoured transition of the fitting is alternatively molded with either an exterior bulge or an interior bulge.Type: GrantFiled: October 29, 1999Date of Patent: April 27, 2004Assignee: BHA Group Holdings, Inc.Inventors: Reinout G.

The upper sleeve is formed of a flexible material which may be manually deformed to pass through an opening in a tube sheet which retains the filter cartridge. The upper sleeve includes a lower lip extending along the interior of the inner screen to securely engage the inner screen. The lower lip is formed integrally with a radially extending ledge which is formed with an upwardly projecting funnel shaped side wall. The side wall includes an inner grove at its upper end which extends about a perimeter of the top sleeve.Type: GrantFiled: March 22, 1999Date of Patent: January 25, 2000Assignee: BHA Group Holdings, Inc.Inventors: Reinout G.
