Beschreibung
Zusammenfassung:	The invention relates to a fan including at least one turbine (4) having blades (5) with a useful air outlet height Hu, said fan comprising an air-suction region located on the side of an end surface of the turbine and including a separation channel at least partially defined by a separating partition (10) such as to separate the air from the suction region into a central flow (A) circulating inside (31) the separation channel, with an intake section Sint, and an annular peripheral flow (B) circulating at the periphery of the separation channel, with an intake section Sext, as well as to direct said flows into the fan towards the blades (5) of the turbine. According to the invention, the ratio of Sint/Sext is 0.5 to 2.
