Abstract: An air purification plant has a partition for spatially separating a contaminated air chamber arranged upstream from a clean air chamber downstream, the partition including a support frame and multiple filter boxes projecting from the support frame, the filter boxes having at least one filter box wall which extends from the support frame into the contaminated air chamber. The filter boxes are each open into the clean air chamber arranged downstream, wherein filter box walls, facing toward one another, of adjacent filter boxes form in each case one filter pocket which is open at the upstream side and preferably at the top and/or bottom, and a suction nozzle is movable from one filter pocket into an adjacent filter pocket. At the downstream side, each filter pocket has a pocket base portion which is at least approximately impermeable to air and has a smooth surface on the contaminated air side.

Abstract: An air purification plant, having a partition wall for the spatial separation of a dirty-air space, which is disposed upstream, from a clean-air space, which is disposed downstream, which partition wall has a support frame and a plurality of filter boxes which project from the support frame in the direction of the dirty-air space, and the filter boxes have at least one filter wall which extends from the support frame into the dirty-air space. The filter boxes are in each case open only in the clean-air space which is disposed downstream, wherein filter walls, which face one another, of adjacent filter boxes in each case form a filter pocket which is open on the upstream side and at the bottom, and for switching from one filter pocket into an adjacent filter pocket a suction nozzle is moved through below the filter box which separates the two filter pockets.
