Abstract

The invention relates to a vibration insulation for gyroscopic machines, especially for roof fans of axial and radial construction, which by virtue of their design permit the use of light-weight structures in the case of roof fans of this type. According to the invention the drive arranged inside the support construction of a fan comprising the motor, the impeller and the mounting plate, which is preferably designed as a carrying grid, is supported so that it is free to oscillate on spring elements, so that no vibrations can be transmitted to the structure by way of the fan components.
