The invention relates to the field of increasing the amount of a gas component in a gas mixture, especially of enriching air with oxygen. According to the invention, the gas concentration arrangement comprises: a discharge chamber (1) including an input side and an output side,—a gas discharge device (2) for generating a gas discharge inside the discharge chamber (1) for generating a pressure gradient on the output side and/or the input side of the discharge chamber (1), and a gas selection device (3), which is arranged on the input side or the output side of the chamber (1) and which is exposable to a gas flow generated by the pressure gradient.
