CIRCULATION DEVICE FOR CIRCULATING AN AMBIENT ATMOSPHERE AND METHOD FOR PRODUCING A CIRCULATION DEVICE OF THIS TYPE

摘要

The invention relates to a circulation device (20) for circulating an ambient atmosphere and to a method for producing a circulation device, said device having a shaft (21), a blade carrier (22) connected to the shaft and a plurality of blades (23) arranged on the blade carrier. Both the blade carrier and the blades are composed of CFC components and are interconnected by means of a frictional connection produced by a connection system having exclusively connecting elements consisting of CFC or graphite and the connection system has a spring element consisting of a CFC material.
