Abstract: Hair drying device comprising an electric motor unit to generate an air flow destined in use to hair drying and/or care, a support to hold the electric motor unit and a spacer duct, hollow inside so that the air flow emitted by the motor unit flows along the tube towards its exit section. The spacer duct has an overall L length at least equal or greater than a R1 distance in which the electromagnetic field emitted by the electric motor unit in use in the specific device measures an intensity at least equal or inferior to a pre-established threshold value of about 2 Milligauss.
