Disclosed is a granular bed dust collector system in which the granular bed of a filter panel is rejuvenated when necessary by interrupting the gas flow through the panel, withdrawing the granular filter media from the panel, dedusting the filter media to dislodge and separate the collected dust from the granules, returning the granular filter media to the filter panel, and reestablishing the gas flow through the panel. One filter panel or a plurality connected in parallel can be serviced, preferably sequentially, by a dedusting unit comprised of a plurality of surfaces which are inclined with respect to the vertical and are spaced both vertically and horizontally so that the filter media cascades from one surface to the other while the dust falls in between.
