The apparatus comprises a protection casing (2) fixable to a wall (3) and housing an air-delivery unit (4). The protection casing (2) has a base portion (6) from the upper part of which a dome-shaped portion (8) projects, and two side portions (9) extending parallelly from the lower part of the dome-shaped portion. The air delivery unit (4) is located between the dome-shaped portion (8) and the side portions (9) and is oscillatably engaged with respect to the casing to be displaced from a non-use position to a use position. When in its use position, the air delivery unit (4) is switched on upon command of a pushbutton (5) housed in the casing (2) and operated by the delivery unit itself.
