Abstract
A fan wheel to be driven in only one rotational direction comprising a central drive unit. A hub positioned coaxially relative to the drive unit and comprising radial fan blades mounted in the hub. The fan blades engage at the base end of the hub between two drive tracks which are fixed relative to the drive unit and are arranged coaxially opposite one another in the direction of the axis of rotation of the fan wheel. The fan blades can be adjusted in terms of their blade angle, into opposing blowing directions, by being driven by a respective one of the drive tracks about their blade axis via a reversal plane which extends perpendicular to the plane of rotation of the fan wheel.
