What are clean rooms?

Clean rooms are required wherever very low levels of airborne substances/particles are allowed. To this end, special walls, doors and floors are installed that close the clean room to the outside and supply filtered air from the ceiling area. The task is to monitor all airborne particles because they are either harmful for people or detrimental for production treatment processes.

Frequent application fields include the medical sector (OP theatres), pharmaceuticals, or the optical or semiconductor industry. The clean rooms are subdivided into nine classes starting with ISO1, where almost no particles are allowed and ending with ISO9 that allows the highest level of particles.

The uniform standard is the EN ISO 14644
