ABSTRACT:
A dust filter apparatus includes a bag chamber having a head mounted on the top thereof and a hopper connected to the bottom thereof for receiving collected dust. The head has a dirty air inlet, a plurality of walled chambers therewithin, a back flow air plenum extending through the walled chambers and a multiplicity of filter bag supports mounted on and depending from the walled chambers in such manner as to permit communication between the walled chambers and the bag chamber. A baffle structure positioned between the head and bag chamber and below the dirty air inlet has apertures through which the bag supports extend, the structure being adjustable in a vertical plane for varying the space between the edges of the apertures and the bag supports. Each bag support has a filter bag connected to and dependeing therefrom into the bag chamber and a collar for directing the flow of air away from the top of the filter bags. An air plenum mounted on the head is formed with a clean air outlet together with means for selectively communicating the interior of the bag supports with the back flow air plenum or the clean air outlet of the air plenum.
