Abstract: Radial compressor and method for the production of a radial compressor, wherein the radial compressor (1) has a compressor housing (10), a compressor shaft (20) which is rotatably supported in the compressor housing, at least one compressor impeller (14) which is arranged on the compressor shaft in the compressor housing, and an inlet insert (12) which is associated with a first impeller stage of the radial compressor in a fluid path in the compressor housing and which has a determined extension in a radial direction (RR) and in an axial direction (AR) of the radial compressor. The inlet insert defines a fluid inlet passage (13) which is arranged in the fluid path upstream of a first compressor impeller and leads to the latter, and the inlet insert is formed of material having a defined material structure, wherein the fluid inlet passage is formed as a subsequently introduced spatial interruption in a material cohesion of the material structure.
