The input air device comprises an entry chamber (11) or inner chamber and intermediate chamber (12) or pressure compensation chamber, in which guide cross ribs (13a1,13a2...) are located. The entry chamber has an elongated form. The air flows into the entry chamber (direction L1) out of the input air channel (C) in the direction of the longitudinal axis (X-axis) to the input air device (10) and penetrates the wall (14) limiting the entry chamber. The limiting wall comprises a holed plate. The air flows through the perforations of the holed plate into the intermediate chamber, which is formed between the front plate (15), pref. a holed plate, acting as air outlet surface, and the wall of the entry chamber to the input air device.
