Abstract
The invention relates to a fan having a fan wheel () comprising fan blades (), which fan wheel extends radially outwards about a rotational axis of the fan () and whose outer radial circumference defines a fan wheel diameter (Dv), and a stator () with air deflecting webs () disposed in the axial direction of flow at a distance (A) from the fan wheel (), which stator extends radially outwards and has a stator diameter (Dl) that is smaller than the fan wheel diameter (Dv), such that the stator () defines a partial cross sectional area of a fan wheel cross sectional area.
