Abstract
This invention relates to self cleaning dust collectors having top mounted filter cartridges. The top mounted filter cartridges include a top mounting plate having an annular flange and an outer peripheral lip to support and carry a sealing gasket. The outer peripheral lip provides lateral support for the gasket under the pressures involved during the operation of the dust collector, and it also serves to prevent over compression of the gasket. The dust collector is further provided with a reverse pulse air cleaning system which includes an air delivery pipe located above the filter cartridges, and with the air delivery pipe being spaced from the dividing wall a sufficient distance to allow for upward removal and easy replacement of the filter cartridges without extensive assembly and disassembly of the dust collector.
