Additionally, a condition that gas for moisture removal becomes the viscous flow is judged as an average free stroke of gas particulates becomes smaller than a diameter of piping of the gas supply system. It is possible to efficiently remove adsorbed moisture on a piping inner surface and in the inside of a valve filter when gas for moisture removal is exhausted in room temperature under such a condition.
