Propeller blower for axial flow of gas or liquid media blows out suctioned air using impeller disc with convex shell blades which extend in a radial direction from the disc

摘要

The propeller blower blows out suctioned air by means of an impeller disc (2) with convex blades(1), adjacent to the inside of the flow channel. The blades are shaped as shell blades with elongate extensions. The end area (20) is pushed into the impeller disc to fasten it. The other end (21) extends in a radial manner towards the outside and has increased radial coverage with an axial component in the direction of the flow.
