Abstract (en)
[origin: WO2018122304A1] The invention relates to a fume hood (1) for a laboratory space, comprising a first hollow profiled element (10, 10'), which is arranged on a front-side end face of each side wall (36) and which has a first pressure chamber (10b, 10b') having a plurality of first openings (10d, 10d'), from which air jets in the form of wall jets (100) consisting of compressed air can be output along the associated side wall (36) into the working space. At least one of the first openings (10d, 10d') is connected to the first pressure chamber (10b, 10b') by means of an elongate channel (10c, 10c'), wherein the channel has a length that is at least 3 times the hydraulic diameter of the first opening in order to avoid flow separation of the wall jet (100) from the side wall (36) in a region from the front side of the working space to at least 25% of the depth of the working space. The invention further relates to a fume hood, wherein such a hollow profiled element (20, 20') is arranged on a front-side end face of the bottom plate (34).
