Abstract: The present invention is a noiseless hair dryer that includes first and second cylindrical bodies extending along an axis, each of the bodies having an intake end and an exhaust end, and the two bodies being arranged in such a manner that the second cylindrical body is disposed within, and carried concentrically by, the first cylindrical body. The second cylindrical body defines a first air flow channel, and the volume between the inner surface of the first cylindrical body and the outer surface of the second cylindrical body defines a second air flow channel. A substantially noiseless fan is mounted at the intake end of the first cylindrical body, and is driven in rotation by a bearing cage, attached to, and disposed circumferentially about, the radially outer surfaces of the fan. A power supply provides electrical energy to drive the outer race of the bearing cage in rotation about the axis.
