Abstract
A collector assembly is configured to vent dust-laden air through at least one filter in one direction using pressure in an air conveyor, whereby dust collects on one side of the filter or filters. The collector assembly is further configured to pulse compressed air through the filter or filters in an opposite direction to dislodge the collected dust into the air conveyor without the dislodged dust entering the atmosphere around the air conveyor.
