A filter assembly (24) includes a first filter portion (80) with a first attachment (100) adapted to attach to a tubesheet (44) to support at least a portion of the first filter portion in a second plenum (40) and to permit fluid communication between the first filter portion and a first plenum (42)

A filter assembly (24) includes a first filter portion (80) with a first attachment (100) adapted to attach to a tubesheet (44) to support at least a portion of the first filter portion in a second plenum (40) and to permit fluid communication between the first filter portion and a first plenum (42). A tubular member (104) is fixed to and extends from the first attachment (100). A pleated filter element (120) is disposed adjacent to the tubular member (104) for support. A second attachment (140) is fixed to the tubular member (104) at a second end of the first filter portion (80) and defines an opening through which fluid may flow. The tubular member (104) is fixed to the first and second attachments (100, 140) with sufficient strength to support the weight of at least one other filter portion. A second filter portion (82) includes a third attachment (180) at a first end and defines an opening through which fluid may flow. A tubular member (186) is fixed to and extends from the third attachment (180). A pleated filter element (188) is disposed adjacent to the tubular member (186) for support. A plate (190) closes a second end of the second filter portion (82). A connection device (510, 522) sealingly connects the second attachment (140) of the first filter portion (80) with the third attachment (180) of the second filter portion (82) and permits fluid communication between the first and second filter portions. The connection device (510,522) has sufficient strength to support the weight of filter portions located on the side of the clamping mechanism opposite the first attachment (100) of the first filter portion (80).

1. A filter assembly for use in a baghouse and adapted to hang in a substantially vertical direction, the baghouse divided into first and second plenums by a substantially planar tubesheet portion with a plurality of openings, the first plenum having a first dimension taken normal to the planar portion of the tubesheet, the second plenum having a second dimension taken normal to the planar portion of the tubesheet and being greater than the first dimension, said filter assembly comprising:a first filter portion including a first attachment at a first end adapted to mount to the tubesheet adjacent an opening through the tubesheet to support at least a portion of said first filter portion in the second plenum and to permit fluid communication from said first filter portion with the first plenum, a tubular member fixed to and extending from said first attachment, a pleated filter element disposed adjacent to said tubular member for support, and a second attachment fixed to said tubular member at a second end of said first filter portion, said second attachment defining an opening through which fluid may flow, said tubular member fixed to said first and second attachments with a strength sufficient to support the weight of at least one other filter portion; a second filter portion including a third attachment at a first end and which said third attachment defines an opening through which fluid may flow, a tubular member fixed to and extending from said third attachment, a pleated filter element disposed adjacent to said tubular member for support, and a plate at a second end of said second filter portion to define a closed end of said second filter portion; and a connection device to sealingly connect said second attachment of said first filter portion with said third attachment of said second filter portion to permit fluid communication between said first and second filter portions, said connection device having a strength sufficient to support the weight of at least one filter portion located on the side of said connection device opposite the first attachment of said first filter portion wherein said second attachment of said first filter portion comprises a flexible annular sleeve and said third attachment of said second filter portion comprises a rigid connection tube wherein said rigid connection tube is received with said flexible annular sleeve to connect said first and second filter portions.
