Abstract
Method and apparatus for a mainly temporary ventilation of a room. A fan blows air from the room through an inflatable balloon, being placed in a permanent opening, e.g. a window, in a wall limiting the room. The balloon is provided with at least one exhaust opening being dimensioned so that an overpressure is built up inside the balloon sufficient to keep the balloon inflated and in abutment with the limitations of the opening.
