Abstract
In a housing enclosing a collector chamber for filtering air laden with dust or other contaminants, a filter element is mounted in line with a clean air opening into the chamber through the housing and is attached so that contaminated air coming into another housing opening into the chamber must pass through the filter media for removing the contaminants from the air. From time to time a stream of pressurized cleaning air is applied in the reverse direction through the first opening to drive contaminants off the filter media. A deflector or diffuser is located in line with the clean air opening to diffuse the applied stream of cleaning air so that it does not directly impinge the filter element. The applied pressurized cleaning air stream completely closes off the clean air opening through which it is applied so that there can be no flow of the cleaning air back through the opening through which it enters so that the air pressure forces the cleaning air through the filter media to dislodge contaminants therefrom.
