In an industrial dust collector comprising a gas intake dirty air chamber, a filtration clean air chamber, and a set of fabric filter bags mounted within the filtration chamber with the bag interiors in fluid communication with the gas intake chamber having a system for cleaning the filtration chamber which includes a venturi in fluid communication with both chambers to effect cleaning of the collector. A method of cleaning the filtration chamber of an industrial dust collector having fabric filter bags mounted within a filtration chamber with the bag interiors in fluid communication with a gas intake chamber is disclosed comprising the steps of evacuating dust from the filtration chamber and directing the evacuated dust into the gas intake chamber. A method is also disclosed for locating ruptures in the filter bags which comprises the steps of forcing gases from the gas intake chamber into the filtration chamber through the fabric filter bags while simultaneously evacuating dust from the filter chamber exteriorly of the filter bags and directing the evacuated dust from the filtration chamber into the gas intake chamber thereby rendering such ruptures visible to an observer stationed within the filtration chamber.
