  • the air outlet before its installation in or on a panel does not yet have a perforated plate, as is known from the prior art, but initially comprises only a housing with a connection piece and a free outlet cross-section for the air. Only after putting on the housing on the perforated plate of a panel, the outlet is complete and can perform its function. Since the housing comes to lie on the perforated plate "from above” or "from outside", it is not visible from the interior and the appearance of the suspended ceiling or the wall paneling is not interrupted at any point.
