There is usually a misunderstanding here. Cleanrooms of ISO classes 1-4 are only required in the rarest of cases. For example, there are sub-sectors of wafer production that produce in nano ranges and rely on automated production in ISO classes 3 and 4. Or the aerospace industry must guarantee absolute sterility for certain applications in order to avoid infecting other planets with foreign germs.
However, even there, Cleanroom ISO Class 1 is almost only a theoretical idea. According to our research, there are actually only three cleanrooms in the world that achieve these conditions. The world’s cleanest Cleanroom is an ISO Cleanroom at the Fraunhofer Institute in Stuttgart, which was used for a mission to Mars.
Achieving the highest particle purity ISO 4 to ISO 1 involves a great deal of effort in terms of filter technology, automation and strict planning of the external environment of the cleanroom. These complex cleanroom solutions are usually only commissioned by corporations or governments and are often planned over years of specific project work. The construction costs and operating costs are correspondingly high.
A modular system such as the one offered by Schilling Engineering cannot achieve these high cleanliness classes. However, as described, they are only very rarely necessary. Our cleanrooms are therefore precisely tailored to the requirements and processes of our customers. Because we plan and build cleanrooms according to the motto: as much as necessary and as little as possible.
