Abstract
The invention relates to a fan having a fan wheel (2) comprising fan blades (3), which fan wheel extends radially outwards about a rotational axis of the fan (1) and whose outer radial circumference defines a fan wheel diameter (Dv), and a stator (4) with air deflecting webs (5) disposed in the axial direction of flow at a distance (A) from the fan wheel (1), which stator extends radially outwards and has a stator diameter (Dl) that is smaller than the fan wheel diameter (Dv), such that the stator (4) defines a partial cross sectional area of a fan wheel cross sectional area.
