    • PROBLEM TO BE SOLVED: To provide a gas separator which can obtain highly-pure product gas, switch each process promptly and achieve high productivity, in a gas separation facility using a pressure swing adsorption method.SOLUTION: An adsorption tower connection part of piping includes a shutoff valve which has a valve element formed by superposing two plate bodies having gas through holes at the same positions so that at least one of the plate bodies is slidable and which is opened/closed by making the gas through holes of the two plate bodies in a communication state or a non-communication state by sliding the plate bodies. A dead volume portion within the piping communicated with inside of the adsorption tower can be minimized. Thus, this prevents gas having a low target gas component concentration from mixing with the highly-pure product gas during process switching, so as to obtain the highly-pure product gas. Since opening/closing operation of the shutoff valve can be performed for a short time, switching of each process can be performed promptly, so as to achieve high productivity.
