Abstract (en)

[origin: WO2016064321A1] The invention relates to a room (1) with a wall (8) with perforations (5, 5a-b) for air suction out of the room. The perforated wall is divided into sections by section delimiters (7,11-13), typically a work table or a shelf. The perforations do, over a main portion of the perforated wall (8), cover a first percentage per unit of area of the wall surface. The perforation on at least a first of the sections, at least at the upper part of the segment covers a second percentage per unit of area of the wall surface, and/or the perforation on at least a second of the sections, at least in the lower part of the segment covers a third percentage per unit of area of the wall surface, where the second and third percentage is larger than the first percentage. The invention is able to particularly effectively remove particles or volatile vapors with a higher or lower density than air, that are emitted under or above the surfaces of the section delimiters.
