Cascade storage system
（重定向自Cascade system）
A cascade storage system is a high pressure gas cylinder system which is used for the refilling of smaller compressed gas cylinders or air cylinders. Each of the large cylinders is filled by a compressor, but the cascade system allows small cylinders to be filled without a compressor. In addition, a cascade system is useful as a reservoir to allow a low-capacity compressor to meet the demand of filling several small cylinders in succession.
