Abstract (en)
[origin: EP2546528A1] The ring has a circular connecting piece (2) formed on a supporting frame (1) that is assembled from a set of frame elements (6) by form and force-fitting connecting elements (3). An axial fan is arranged in the connecting piece, which is formed of circular segments (22) to be circumferentially arranged one after the other. The segments are connected to each other and with the frame by form and force-fitting or material-bonded connections or by other connecting elements. The frame includes a rectangular quadratic circumferential contour with four corners and a center opening.
