ABSTRACT:
A dust collector comprising a hopper, an exhaust chamber, a wall separating the hopper and the exhaust chamber and including an opening, a hollow filter assembly for filtering contaminated air flowing through the opening from the hopper, the filter assembly comprising filter medium and having upper and lower ends, the upper end of the filter assembly registering with the wall opening such that the hopper is generally sealed from the exhaust chamber except through the wall opening and the filter medium of the filter assembly, an inlet into the hopper for introducing contaminated air into the hopper so that the contaminated air is caused to flow to the exhaust chamber through the filter medium whereby airborne contaminants are accumulated on the filter medium, a nozzle for selectively directing reverse pulses of air into the wall opening from the exhaust chamber whereby the reverse air pulses enter the filter assembly and generate airflow through the filter medium in the reverse of the direction of contaminated airflow to remove accumulated contaminants from the filter medium, and a deflector cylinder housed inside the lower end of the filter assembly for preventing the air pulses from impinging upon the filter medium.
