PCT No. PCT/SE91/00444 Sec. 371 Date Dec. 16, 1992 Sec. 102(e) Date Dec. 16, 1992 PCT Filed Jun. 20, 1991 PCT Pub. No. WO91/19557 PCT Pub. Date Dec. 26, 1991.A device for mounting vertical bag-shaped filter elements (15) in a filtering chamber in a filtering installation for cleaning contaminated gases which are conducted into the filtering chamber to be filtered by the bag-shaped filter elements and conducted, via the bag openings, to a chamber for clean gas which is located above and separate from the filtering chamber and from which the gases are discharged from the filtering installation, comprises a horizontal, lower tubular element (1) and a horizontal, upper tubular element (4) which extends along the lower tubular element (1) to which it is connected. The lower tubular element (1) forms a clean-gas chamber and has a series of first through holes (10) in its lower tube-wall portion (2b). The bag-shaped filter elements (15) can be mounted on the lower tubular element (1) with the bag openings opposite to the first holes (10). The upper tubular element (4) is closed at one end, and its interior communicates with that of the lower tubular element (1) via a series of second holes (11 ), each of which is vertically aligned with one of the first holes (10). The upper tubular element (4) is adapted, at the other end, to be connected to a pressure source via a regulating valve for producing pressure pulses to clean the bag-shaped filter elements (15).
