Axial ventilation device, premises equipped with such a device
First Claim
1. An axial ventilation device comprising at least three axial fans arranged at the ends of a polygon and each axial fan includes two motors and each of these motors is connected to another axial fan so as to form a network wherein each axial fan comprises a case ring exhibiting symmetry of revolution extending longitudinally along an axis of the fan, a plurality of blades arranged inside the case ring and fixed to a hub, a shaft of the axial fan to which the hub is secured, said shaft extending along the axis of the axial fan, at least one motor designed to drive a drive shaft in rotation about the axis of rotation of said motor, in which the motor is situated on the outside of the case ring and the drive shaft is connected to the shaft of the axial fan by a coupling device so as to perform the rotary driving of the shaft of the axial fan, in which said axial ventilation device is further characterized in that one and the same drive shaft is designed to drive the rotation of at least the shafts of two axial fans.
