SMC's CQS clean room, compact air cylinder has 4 bore sizes. Standard strokes range from 5 to 50mm. 10/11-C(D)QS series, available for clean environment, prevents particle generation in a clean room. 21/22-C(D)QS series offers the same structure as the clean series, and are for the environment in which the use of copper, fluorine and silicon are restricted.
