A tongue region (8) forming a transition between the spiral wall and the channel wall is designed in a partially adjustable manner and/or bezels are designed in a sectionally adjustable manner. Parts of the tongue region and/or parts of the bezels include an actuator device and/or a connecting device for connection to the actuator device. The tongue region includes tongue walls (16, 17) with tongue wall leading edges (18, 19), respectively. An independent claim is also included for a method for operating a radial fan assembly.
