ABSTRACT:
A dust collector for removing entrained particles from an air stream that includes filter elements that are periodically cleaned, such as by a pulse jet, to remove the collected particles therefrom, which particles move downwardly to a hopper at the bottom of the dust collector. A container having a removable lid and a drum portion are disposed beneath the hopper to receive the collected dust particles for ultimate removal, and the lid is securely sealed to the drum portion of the container by an annular inflatable balloon-type seal that extends between a flange on the lid and the side wall of the drum, with the air used to operate the inflatable seal preferably being obtained from the existing pulse jet system for the dust collector.
