That is, the functions of removing moisture and adsorbing components in the processing gas are shared between the moisture absorption element and the adsorption element. Therefore,
Even if the process gas contains a high concentration of water, the adsorption element can maintain the original adsorption performance while preventing the adsorption performance from being lowered due to the water content.
