ABSTRACT:
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.
