Abstract: A wall box for a ventilation system comprises a housing delimiting an interior, in which a through-flow region is defined. In the interior is arranged at least one flap arrangement having a flap arranged on a suspension mounting. For an area A of a cross section of the interior perpendicular to a flow direction, A/K>2/πr, wherein K indicates an area of an enveloping circle with smallest possible radius, which circle completely conceals the cross section of the interior. The flap of the at least one flap arrangement has at least in an open position a flap contour which in regions adjacent to a pivot axis is adapted to a cross-sectional contour of the interior in the respective region adjacent to the pivot axis.
