There is usually a misunderstanding here. Cleanrooms in ISO classes 1-4 are only needed 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, an ISO Class 1 cleanroom is almost 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 cleanroom’s external environment. These complex cleanroom solutions are usually only commissioned by corporations or governments and are often planned in 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. That is why our cleanrooms are precisely tailored to the requirements and processes of our customers. Because we build and plan cleanrooms according to the motto: as much as necessary and as little as possible.
