Filter mounting system

A filter cartridge mounting system for use in a baghouse having a tubesheet with a plurality of openings, said filter mounting system comprising:

• a filter cartridge including:
• pleated filter media;
• structure for supporting said filter media;
• a rigid non-metallic tubular mounting collar integrally formed with said filter media and said supporting structure to secure said filter media and said supporting structure to said collar, said mounting collar having a tapered surface portion extending from a tubular portion;
• and
• a gasket made of a flexible elastomeric material, said gasket having a tubesheet receiving portion and a filter receiving portion axially spaced from said tubesheet receiving portion, said filter receiving portion having a tapered surface portion;
• said tubular portion of said mounting collar adapted to be positioned within said gasket and engaging said filter receiving portion to effect sealing engagement of said tubesheet receiving portion of said gasket against a portion of the tubesheet;
• and
• said filter receiving portion is tapered to force a portion of said tubesheet receiving portion of said gasket so a first sealing portion of said tubesheet receiving portion engages another portion of the tubesheet upon engagement with said tapered surface portion of said mounting collar during installation of said filter assembly in said gasket.

A filter mounting system for use in a baghouse having a tubesheet with a plurality of openings, said filter mounting system comprising:

• a filter assembly including:
• filter media;
• and
• a rigid non-metallic tubular mounting collar attached to said filter media to mount said filter media relative to the tubesheet, said mounting collar having a tapered surface portion;
• a gasket made of a flexible elastomeric material, said gasket having a tubesheet receiving portion and a filter receiving portion extending from said tubesheet receiving portion, said tubesheet receiving portion having a pair of axially spaced tubular surfaces and a tapered surface portion that forces a first portion of said tubesheet receiving portion of said gasket into engagement with a first portion of the tubesheet upon engagement with said tapered surface portion of said mounting collar during installation of said filter assembly in said gasket;
• said mounting collar including a pair of axially spaced projections extending from said collar, said mounting collar adapted to be positioned within said tubesheet receiving portion of said gasket and each of said projections engaging a respective one of said tubular surfaces to force portions of said gasket against surfaces of the tubesheet adjacent the opening to effect sealing engagement therebetween, said mounting collar also adapted to be positioned within said filter receiving portion of said gasket and engage said filter receiving portion to effect sealing engagement of said tubesheet receiving portion of said gasket against another portion of the tubesheet adjacent the opening, said filter receiving portion extending from said tubesheet receiving portion to force one portion of said gasket into sealing engagement with a surface of the tubesheet upon engagement with said mounting collar.
