Abstract
A fan, with fan blades, especially used for the cooling of a motor vehicle, with the fan blades being fixed to a fan hub. In spite of being made of only a small amount of material, the fan is highly resistant to the flow conditions in the motor vehicle, each fan blade being bent rearwards at an angle in the direction of a blade root, an angled region of the fan blade being at least partially bent downwards towards the fan hub.
