The fan comprises: a support structure (12) adapted to be fixed to a ceiling a bladed rotor (14) supported rotatably by the support structure (12) for rotation around a vertical axis of rotation (z), the bladed rotor (14) comprising a hub (28) and a plurality of blades (30) fixed to the hub (28) a motor (16) carried by the support structure (12) a motion transmission mechanism (18) arranged to transmit to the bladed rotor (14) the rotary motion generated by the motor (16) to control the rotation of the bladed rotor (14) around the axis of rotation (z), the motion transmission mechanism (18) comprising a drive shaft (32) on which the hub (28) of the bladed rotor (14) is mounted so as to be drivingly connected for rotation therewith and a nebulizer device including at least one nozzle (20) and a primary water supply conduit (22) in fluid communication with said at least one nozzle (20). The at least one nozzle (20) is mounted beneath the hub (28) and/or on the blades (30) of the bladed rotor (14). The drive shaft (32) has an axial hole (34) through which the primary water supply conduit (22) extends. The motion transmission mechanism (18) comprises a driving pulley or gear wheel (42) which is carried by a motor shaft (40) of the motor (16) and a driven pulley or gear wheel (44) which is carried by the drive shaft (32) and is arranged to be driven by the driving pulley or gear wheel (42) by means of a belt or chain (52, 54).Linvention concerne un ventilateur comprenant : une structure de support (12) conçue pour être fixée à un plafond un rotor à aubes (14) porté de manière rotative par la structure de support (12) afin de tourner autour dun axe vertical de rotation (z), le rotor à aubes (14) comprenant un moyeu (28) et une pluralité daubes (30) fixées au moyeu (28) un moteur (16) porté par la structure de support (12) un mécanisme de transmission de mouvement (18) conçu pour transmettre au rotor à aubes (14) le mouvement de rotation produit par le moteur (16) afin
