ABSTRACT An axial blower with an intake that tapers conically into a cylindrical component. An impeller rotates inside the cylindrical component. A stationary channeling ring of approximately the same diameter as the cylindrical component is positioned upstream of the impeller and surrounded by an annular channel. The channeling ring is approximately equidistant from each end of the annular channel. Guide vanes are positioned inside the annular channel and adjusted in relation to its axis. To make the blower easier and less expensive to manufacture and to increase its breakaway limit, the guide vanes consist of flat sheets of metal and both their upstream and their downstream edges slope.
