The arrangement (10) is composed of four individual modules (11) and comprises four air supply devices (12) and three air outlet members, namely a central plate (14) with great permeability, a second plate (15) surrounding the first with lower permeability, and a third plate (16) surrounding the second plate (15) with even lower permeability. Thus, three air flows with different flow speeds are generated. The air inlets are arranged distributed on the housing and in particular in each case one on two adjacent, outer side walls of each module (11). <IMAGE> |
