Abstract
An improved dust collector having a housing that encloses clean-air and dirty-air chambers with an elongate non-vertical annular hollow filter with an end accommodating the flow of clean air positioned in the housing, and a nozzle connected to an air source where the nozzle is positioned so as to inject a blast of air into the filter in order to dislodge particulate accumulated on the outside of the filter. The improvement involves a turbine positioned within the filter and linkage joining the turbine with respect to the filter such that a blast of air from the nozzle turns the turbine which thereby turns the filter whereby the filter is reoriented to facilitate removal of particulate collected thereon.
