Abstract
An adjustable pulsator for a hair dryer has a rotatable disc 14 with peripheral blades 17. A housing 18 has apertures 26 which are effectively closed by more or the less by protrusions 27 when a ring 19 supporting the protrusions 27 is rotated relative to the housing 18. The more open the apertures, the faster the disc 14 will rotate in use.
