At Festo, low-cost standard pneumatic components take the place of complex special designs. This is possible because the quality concept is compatible with almost all standard series products. These standard pneumatic components are suitable for use in a class 7 clean room according to ISO 14644-1.


Close-to-standard products for clean rooms up to class 4

More stringent requirements, but still an optimum cost/benefit ratio. Class 4 also means standard products at Festo, but with one restriction: these products are not kept in stock. However, they can still be delivered to you within a very short time.
