<p>The device has a flow guiding housing (50) for incoming air, where the housing has an area (52) in which air from a blower is guided away upwards, and another area (60) in which incoming air is guided inwards. An air blowing device stays in fluid effective connection with the latter area. The air blowing device has a by-pass area at which the two areas are fluid-effectively connected, and at which a flow by-pass takes place. The air blowing device has an air blowing row attached to a nozzle row, and another air blowing row (114) attached to another nozzle row (136).</p> |
