ABSTRACT:
A dust collector filter cleaning control system employing high-pressure compressed air pulses, wherein the dislodged dust particulate is prevented from returning to the filters after the high-pressure compressed air cleaning thereof by briefly maintaining a positive low-pressure compressed air within the cleaned filters so that the particulate removed from the filters has time to drop into the collector hopper. The same source of compressed air is employed for both the filter cleaning air pulses and the sustaining low air pressure for preventing the re-entrainmnet of the dust particles into the filters.
