Its primary goal is to separately or globally protect the Product, the Operator and the Environment. The air entering these rooms is filtered at different stages of the air treatment on different levels of filtration efficiency depending on their classification ( Iso 5 clean room to Iso 8 clean room ) and their state (rest or operation) . More generally, we find three levels in cascade ranging from gravimetric pre-filtration (G), opacimetric filtration (F) to absolute filtration (H or U). The latter can be located either in the central or in the terminal position so as not to diffuse any contamination of the aeraulic network. The mixing rate is an important parameter for obtaining the projected class and for the kinetics of decontamination thereof. The risk of particulate contamination having several possible origins and consequently several sources of negative effects, the two previous parameters (filtration and mixing rate) will be supplemented by a concept of pressure gradient. This parameter will be mainly determined according to the dangerousness of the product or its sensitivity to degradation or bio contamination. Other parameters more related to the destination of the room will also be controlled: temperature, humidity, risks of explosiveness (Atex) etc ... The control and monitoring (GTC) of the regulation of all these parameters are decisive elements for the proper functioning of the clean room.
