Abstract: The air disperser (1) includes an air inlet (2), a pipe (3) defining an air outlet area equipped with one or more atomizers (4), an outer wall (7) and a space (8) defined by the pipe wall (9) and the outer wall (7) of the air disperser. The space (8) has a plurality of guide vanes (10a-10l) positioned substantially vertically in the axial direction and substantially on the radii between the pipe wall (9) and the outer wall (7) of the air disperser. At least one (10e) of the guide vanes is covering at least 90% of the full radius from the pipe wall (9) in the direction towards the outer wall (7) of the air disperser, and the rest of said guide vanes being distributed on radii along the circumference of the pipe (3).
