Abstract (en)
The conveyor device has a flow channel (60) having a channel wall (62). The flow channel has a vane occupying impeller, which is rotatably arranged in such a way that a gap is formed between vanes and channel wall. The perforations are formed in the channel wall in the region of the gap. A sound-absorbing material (26) is arranged opposite to impeller side of channel wall. The channel wall and sound-absorbing material are integrally formed with each other.
