ABSTRACT:
A filter cartridge for use in a baghouse having a tubesheet with a plurality of opening. A flexible snapband is biased towards engagement with a surface defining one of the openings in the tubesheet and is adapted to receive a portion of the filter cartridge. The snapband has a first surface and a second surface with a pair of protrusions separated by a groove adapted to receive a peripheral edge of one of the tubesheet opening. The pair of protrusions sealingly engage surfaces of the tubesheet. The filter cartridge includes filter media. Structure supports the filter media. A rigid non-metallic tubular collar is integrally formed with the filter media and the structure to secure this filter media and the structure to said collar. The collar includes a pair of longitudinally spaced continuous projections extending radially from the collar. The collar further includes an annular surface extending from the collar for establishing the position of the filter cartridge relative to the tubesheet The collar is adapted to be positioned within the snapband and engage the first surface of the snapband to effect sealing engagement of the snapband against a portion of the opening in the tubesheet. The first projection extends radially the said collar to further force a portion of the snapband into sealing engagement with a surface of the tubesheet. The second projection further forces another portion of the snapband into sealing engagement with another surface of the tubesheet.
