Abstract
In a side-channel compressor having a rotor rotatably supported in a housing, the improvement wherein at least one dust stripper protrudes into a gap between the housing and a rotor to prevent the accumulation of dust in the gap. Preferably, the dust stripper protrudes into a radial gap between a lateral extension of a blade ring portion of the rotor and a lateral extension of the housing. Additionally, the dust stripper is preferably circumferentially located in the inlet half of the compressor so that the pressure gradient in the compressor assists in the removal of dust stripped by the dust stripper. Additionally, or in the alternative, an axially extending dust stripper may be provided in an axial gap between the housing and a hub portion of the rotor.
