ABSTRACT:
The invention relates to a fan arrangement comprising a radial or diagonal fan (370) with which a direct current motor (32) is associated as drive motor, further comprising a digital control element (23, 24) such as a microcontroller or microprocessor, associated with that direct current motor (32), and comprising a program, associated with that digital control element (23, 24), for controlling the current flowing through the direct current motor (32), which program is embodied to generate a substantially constant current in the motor (32) in the working rotation speed range of the fan.
