A fan including a main body with a vertical development with respect to a support base on which the main body is located in a condition of use. The fan has a rear longitudinal aperture, for the emission of a stream of air toward the outside, and also comprises an air suction and distribution unit, and a channeling element (20) positioned in proximity to the longitudinal aperture (16). The channeling element allows to divert the stream of air (W) so that it is conveyed toward a front part of the fan (10), at least partly following a profile (40) of an external surface (22) of the main body (12).
