A side channel compressor comprises an inlet port ( 42 ) for gas and an outlet port ( 44 ) for compressed gas as well as a side channel ( 32 ) which provides a flow connection between the inlet port ( 42 ) and the outlet port ( 44 ), the cross-section of the side channel ( 32 ) diminishing between the inlet port ( 42 ) and the outlet port ( 44 ). The side channel ( 32 ) has at least one section in which it has a cross-section in the form of a half ellipse and in which the maximum depth of the channel ( 32 ) continuously diminishes towards the outlet port ( 44 ).
