FIELD: ventilation.
SUBSTANCE: invention relates to axial fan for cooling air movement, in particular to internal combustion engine of vehicle including the blades (13, 14, 15) of the fan fixed on the hub (12) and having a pressure side and suction side, rear edge (16, 17, 18) and depth (t), and the ramp (13a, 14a, 15a) of the hub on corresponding pressure side of the blades, with a lifting opposite to rotational direction (D) of axial fan (11). Rear edge (16, 17, 18) has outer zone (16a, 17a, 18a) located radially outside the hub ramp (13a, 14a, 15a) and inner zone (16b, 17b, 18b) located radially inside the hub ramp (13a, 14a, 15a).
EFFECT: invention is aimed at airflow improvement.
