Claim 0:
1. A downdraft element comprising a first flow opening and a second flow opening, the first flow opening being arranged relative to the second flow opening at an angle 45°≤α≤135° so that at least the mean flow direction of a fluid entering the first flow opening and exiting the second flow opening or vice versa can be deflected by the angle α, wherein the downdraft element has, on an inner side between the first flow opening and the second flow opening, at least one damper material receptacle and at least one damper inserted into the damper material receptacle; the damper receptacle being located on a distal inner side of the downdraft element, the damper receptacle having a least one flow guide element providing a retaining element for holding an end of the damper and, wherein the damper is shaped such that an inner side of the damper over which the fluid can flow merges substantially evenly with the inner surface of the damper via the flow guide element and wherein the downdraft element is of two-shell design with two shell parts, the shell parts being clamped, bonded, welded and/or screwed to one another.
