Abstract (en)
[origin: EP2236837A2] The axial flow fan (7) has fan blades having axial depths from inflow edge to outflow edge. The outflow edges of the fan blades in the axial direction project beyond the trailing edge of the annular surface and form a blade overhang. Flow guides (11) are arranged radially outside the fan blades and in an axial region of the blade overhang.
