The invention relates to a radial compressor (2) comprising an impeller (4), a motor (8) for driving the impeller (4), which motor (8) exhibits a shaft (40), a housing (10) for the motor (8) and a distribution system (18) for a service fluid for the motor (8), wherein the distribution system (18) comprises a main feed (28), a manifold (36) and at least two feed branches (37, 38), wherein the service fluid can be conducted through the main feed (28), the manifold (36) and the at least two feed branches (37, 38), and wherein the main feed (28) and the feed branches (37, 38) join in the manifold (36). A radial compressor with an enhanced design may be achieved in that the distribution system (18) is an integral part of the housing (10) and in that the housing (10) comprises several housing parts (12, 14, 16), which are connected to each other and which are arranged adjacent to each other in longitudinal direction of the shaft (40), where the distribution system (18) extends through at least two of the housing parts (14, 16).
