ABSTRACT:
A roof drill dust collector is disclosed which comprises a closed housing in which dust-laden air is carried through a first stage dust separator, a second stage dust separator, and a third stage dust filter, before being expelled to open air. The first and second stage separators deposit dust in first and second collection chambers having a common floor, being a hinged door. The housing has means therein for automatically, in sequence, spraying streams of water on the collection chamber walls, opening the hinged door to dump the collected dust, sending a reverse pulse of air through the third stage filter, and closing the hinged door.
