A CLEAN ROOM SYSTEM AS WELL AS A COMPUTER IMPLEMENTED METHOD FOR CONTROLLING SUCH CLEAN ROOM SYSTEM

The invention relates to the field of clean room facilities for manufacturing of a pharmaceutical product or item according to a sequence of manufacturing steps under extreme low levels of particulates. According to a first aspect of the disclosure a clean room mimicking system is proposed, for example for the manufacturing of a pharmaceutical product or item according to a sequence of manufacturing steps under extreme low levels of particulates, the clean room system at least comprising one clean room facility being composed of multiple air conditioned compartments, each of the multiple air conditioned compartments equipped for performing at least one of the manufacturing steps, wherein the multiple air conditioned compartments are mechanically interconnected and each are constructed in accordance with an associated clean room classification ranging from high to low in terms of the number and size of particulates permitted per volume of air, seen in the direction of the sequence of manufacturing steps through the clean room facility.
