Abstract: A hair drying apparatus comprises a blower with a scroll internally provided with a fan having radial blades with flat lower edges and upper edges shaped to adapt to the scroll so as to define a substantially spiral path. Disposed below the scroll is an open external air inlet chamber containing the lower part of a motor which drives the fan so that said motor is cooled by the air in transit from the outside. The chamber substantially constitutes an extension of the spiral path in the scroll to which it is connected through a vertical aperture above which is disposed a horizontal baffle substantially flush with the lower edges of the blades of the fan.
