  • Patent number: 6726735
    Abstract: 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.

  • Patent number: 6676722
    Abstract: A baghouse filter having a filter media and an end cap is provided. The filter media has a longitudinal axis, and the end cap has an outer peripheral side wall. The side wall has first and second edges. A first recessed channel extends between the first and second edges of the side wall, and a second recessed channel extends from the first channel. The first and second channels define a connection area at which the filter connects to the tubesheet at an opening in the tubesheet. Also, a method is provided for installing a filter on a tubesheet having first and second sides separating plenums of a baghouse. The method includes providing a filter having structure for attaching to a tubesheet opening from either side, selecting the side to install the filter and installing the filter on the selected side.

  • Patent number: 6017378
    Abstract: A filter cartridge according to the present invention is provided having a unitary structure with a pleat pack formed securely about an interior screen. Opposite ends of the pleat pack and interior screen are integrally formed within a bottom end cap and an upper sleeve. The bottom end cap is constructed to follow the contour of the pleat pack to minimize the collection of dust about the bottom perimeter thereof. 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.
