Abstract

A side channel blower (1), in particular for supplying combustion air to the auxiliary heater (2) of a motor vehicle, has a body (3) axially connected to an impeller wheel (4). The blower body (3) has an inlet channel (5), an outlet channel (6), a curved side channel (8) at the axial connection side (7) with the impeller wheel for connecting the inlet channel to the outlet channel, and a separating piece (9) which form together the 360.degree. of the circumference of the axial connection side (7). The separating piece (9) is produced as a separate part, in particular as a casting. This is advantageous for the manufacture and for optimizing the noise level and aerodynamics of the blower.
