1. A side channel compressor for compressing gas, the side channel compressor comprising:
a housing, which forms a side channel; and
an impeller drive arranged in the housing, which comprises an impeller arranged in the side channel for driving gas through the side channel,
wherein the housing forms a feed channel, that is fluidically connected to the side channel, for feeding gas to the side channel and a discharge channel, that is fluidically connected to the side channel, for discharging gas out of the side channel,
wherein the feed channel branches into two separate channel arms each extending along a channel arm center axis,
wherein the housing is subdivided along a separating plane into a first housing part and a second housing part, which, sealed, lie against one another,
wherein the discharge channel is separated at least in sections along the separating plane into a first discharge channel part arranged integrally on the first housing part and a second discharge channel part arranged integrally on the second housing part,
wherein the discharge channel or the first and second discharge channel parts are passed through between the two channel arms of the feed channel,
wherein either the first discharge channel part, forming a gas outlet opening arranged completely apart from the separating plane, opens out on a connecting surface of the first housing part for conducting gas, or
the second discharge channel part, forming the gas outlet opening arranged completely apart from the separating plane, opens out on a connecting surface of the second housing part for conducting gas, and
wherein the connecting surface is arranged at a distance from the impeller in a radial direction.
