This patent describes a gas filtering apparatus having dirty and clean air chambers separated by a generally horizontal partition presenting a plurality of openings each provided with a filter bag. An improved bag cleaning arrangement is described comprising: an upright air accumulator tank for receiving and accumulating a supply of air under pressure; means for mounting the tank in the clean gas chamber for rotation about a substantially vertical axis; drive means for rotating the tank about the axis; means for supplying air under pressure to the tank as same is rotating; a substantially horizontal air distribution arm extending from the tank and rotating therewith in a path carrying the arm over the partition the tank providing the sole source to air flow to the arm; a plurality of outlets spaced along the arm for discharging air therefrom in pulses, each outlet being located to successively align with openings in the partition as the arm rotates; valve means for controlling the flow of air from the tank into the arm; and valve control means for intermittently opening and closing the valve means to allow air from the tank to enter the arm in a pulse each time the valve means is opened.
