A scrubber installation (1) for cleaning, for instance, fire smoke gas comprises a preseparator (13) having at least one perforated plate (19, 19') upstream of which a set of first nozzles is arranged, with the purpose of spraying the upstream side of the plate with flushing liquid so as to dampen and cool the smoke gas and flush the holes of the plate. One or more sets of nozzles (25, 25') are arranged downstream of the plate which squirt liquid in the reverse flow of the gas through the holes with the purpose of dampening and cooling the gas additionally. Water steam is condensing on the solid particles acting as condensation nuclei, which still are included in the gas when it passes the plate, the liquid and the particles forming agglomerates the sizes of which facilitate separation in the following cleaning devices (14, 15, 16).
