Abstract
The invention relates to a radial blower for a cleaning device for a combine harvester, with several component blowers, where each of the blowers is arranged in an associated housing, each of which is connected to a wind duct that during operation guides the air stream generated by the component blower to the cleaning device, wherein the wind ducts have side walls that are connected with convex curvature to the side walls of the housing of the component blowers and wherein the side walls of adjacent wind ducts are connected to each other at the end facing toward the cleaning device, in which the side walls of the wind duct have a convex curvature over their length.
