1. A side channel compressor for compressing a gas, the compressor comprising:
a housing having at least one annular groove, the at least one annular groove having an internal edge relative to a central axis of the compressor, a base edge extending from to the internal edge, and an annular web protruding from the internal edge opposite the base edge, the annular web providing a retaining edge;
at least one impeller arranged in the housing and configured to be driven in rotation about the central axis; and
at least one seal assembly disposed in the at least one annular groove and including:
at least one sealing device configured to seal at least one gap between the housing and the at least one impeller, the at least one sealing device configured to be forced radially outward with respect to a central axis to seal the at least one gap, and
at least one sealing-device-holding device configured to hold the at least one sealing device in an axially secured fashion with respect to the central axis, and which includes at least one main holding body,
wherein the at least one sealing-device-holding device has at least one spring projection bent out from the at least one main holding body, the at least one spring projection having a free end abutting against the retaining edge and the internal edge, and forming at least one opening and projecting radially with respect to the central axis from the at least one main holding body and supported in relation to the housing, forcing the at least one sealing device radially outward with respect to the central axis, and
wherein the at least one sealing device covers the at least one opening of the at least one sealing-device-holding device.
