Abstract

The radiation fan is for ventilating tunnels and has at least one fan (5) arranged in a shaft (4). At least one nozzle arrangement (6,7) is fitted at the inlet (8) and/or outlet side (9) of the shaft and is preferably provided with a noise damper. air guide (23) to the nozzle arrangement is inclined in relation to the fan shaft, so that the inflow (14) and/or outflow direct (15) in relation to the through flow direction (16) of the fan shaft forms an angle (17). This angle is between 3 and 25 degrees
