AIR PURIFICATION INSTALLATION

The present invention relates to an air purification installation (1) which has a partition (3) for spatially separating a contaminated air space (5) arranged upstream from a clean air space (7) arranged downstream the partition (3) has a supporting frame (13) and multiple filter boxes (17) which project from the supporting frame (13) in the direction of the contaminated air space (5) and the filter boxes (17) have at least one filter wall (15) which extends from the supporting frame (13) into the contaminated air space (5). The filter boxes (17) are in each case open only into the clean air space (7) arranged downstream wherein filter walls (15) facing toward one another of adjacent filter boxes (17) form in each case a filter pocket (21) which is open at the upstream side and at the bottom and a suction nozzle (33) is in order to change over from one filter pocket (21) to an adjacent filter pocket (21 ) moved through under the filter box (17) that separates the two filter pockets (21).
