Zusammenfassung:An improved fan arrangement features a radial or diagonal fan ( 370 ) with which a direct current motor ( 32 ) is associated as its drive motor, further comprising a digital control element ( 23, 24 ) which executes a program, for controlling the current flowing through the direct current motor ( 32 ), which program is so configured that it applies a substantially constant current in the motor ( 32 ) in the working rotation speed range of the fan.
