When it comes to building a cleanroom, nothing can be left to chance and it is absolutely essential to involve specialised professionals, who will be able to support the client in every phase of the project: from the initial definition of the objectives to that of the technical parameters, from the design to the actual production of the controlled contamination environment, from its implementation and approval, to its maintenance and cleaning.

Cleanroom professionals will not only be able to design and create an environment that meets the quality and regulatory standards necessary for the actual application defined in the design phase of the project but also to evaluate the best solutions in terms of equipment.

It is, in fact, important to remember that, depending on the needs of the client and on the regulations of the law, there are different classes of purity and hierarchical areas even in the area of cleanrooms. The distribution of purity classes is defined by DIN guidelines and the so-called “purity dream” identifies a class 10 or higher.

Professionals in the production of cleanrooms and controlled contamination environments will be able to accurately evaluate the different design criteria related to the most varied needs, which tend to differ, often significantly, according to the specific area of application. In general, however, it is possible to assert that, since the cleanroom must be completely sterile and clean, and must maintain stable conditions of temperature, pressure, and humidity inside, it will be necessary to design an incredibly detailed and professional ventilation system.

Building a cleanroom: from the choice of the materials to that of the equipment

In most cases, the greatest source of contamination for any cleanroom is represented by the human element and, depending on its presence – as well as on that of artefacts that must be protected in the cleanroom – professionals will identify the best solutions in terms of materials, floors, ceilings, floodgates, furniture, and so on.

In addition, experts will also design the access to the clean room through special decompression chambers for materials and people and the necessary air showers. In these spaces, the detachment of the contaminating particles will take place through powerful air jets and specific filtering systems that will guarantee the aspiration of particles – and, therefore, prevent their introduction into the cleanroom.

To build a cleanroom, professionals will then identify the best materials to use. In this case, these will be the materials capable of meeting specific characteristics, among which it is worth mentioning:

• Minimum degassing
• Smoothest surface possible
• Friction resistance
• Robustness
• Easy to clean and sanitise
• Resistance to disinfectants
• High dispersion capacity
• Good abrasion resistance

In conclusion, both in terms of preliminary design and of the actual implementation of a clean room, it will never be sufficient to act in total autonomy but it will always be essential to directly involve the experts in the field.
