Abstract A bag filter having a plurality of bags contained in a bag house. One end of the bags is secured to openings in the bag house floor and the other ends are suspended from an elongated hanger plate located in the upper part of the bag house. The plate is provided with slots at spaced intervals along its length, and each slot extends from the edge of the plate toward the center line thereof. Suspension rods attached to the top of the bags extend upwardly, pass through the slots in the hanger plate, and are selectively movable laterally into and out of the slots. Springs rest on the plate, urge the rods upwardly, and thus maintain tension on the bags. For initial installation or replacement of the bags, suspension rods can be inserted in or removed from the slots in the plate, with the springs in place, by firm lateral pressure on the rods.
