ABSTRACT:
A blower having a discharge tube, which can be secured to a housing, for guiding a stream of air is provided. The air stream flows in a main stream direction in the discharge tube and in a discharge stream direction out of the discharge tube. The discharge stream direction forms an angle of greater than 0° with the main stream direction. The discharge stream direction has a transverse component that extends perpendicular to the main stream direction, which produces a force in the discharge tube perpendicular to the main stream direction. To reduce the transverse force produced in the discharge tube, a partial air stream is branched off out of the discharge tube and flows in a partial stream direction that has a compensation component that is directed opposite to the transverse component.
