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). |
