Abstract
In a system for dust collection and filtering of particulate matter from an air stream, wherein dustladen air is passed through a plurality of bags constructed from suitable effective filtering material so as to collect dust and particulate matter along an internal confined surface of the bag while permitting cleaned air to pass through the bag material, an apparatus for periodically generating an air shock wave which propagates along the bag surface and physically vibrates the bag material. The apparatus includes a plurality of air jets positioned adjacent a bag end in non-axial alignment with the bag, in combination with a circumferential deflection collar surrounding the bag end so as to receive the initial air shock wave and deflect the pressure forces along the circumferential length of the bag.
