A clean room requires higher building standards than many other buildings. Building materials used for clean rooms are different from those used for other construction projects.

Design of clean rooms should take into account the following:

The construction of each clean room requires a tailor-made solution based on product requirements.

What are Clean Rooms and Clean Zones?

A clean room is a controlled environment in which pollutants such as dust, airborne microbes and aerosol particles are filtered to provide the clearest possible area. Most of these facilities are used for the manufacture of electronics, food and pharmaceuticals, cosmetics and medical equipment, as well as for various types of examinations, manipulations and surgical interventions in the medical sphere.

Cleanrooms can be divided into different pollution levels for the number of particles allowed per cubic meter in a room. Cleanrooms also control temperature, humidity and airflow.

There are two types of cleanrooms and they differ in airflow.

«Turbulently ventilated» room receives clean filtered air through high-efficiency air filters in the ceiling. The fresh air mixes with the indoor air and removes airborne pollution caused by humans and machinery. This process is carried out by exhaust vents located in the lower part of the wall.

Cleanrooms with unidirectional airflow use much more air than the first ones. High-efficiency filters are installed throughout the ceiling to ventilate clean rooms.

The air moves in one direction at a speed of 0.3 to 0.5 m/s. Then the air comes out through the floor, removing the air pollution from the room. For a room with a width of less than 4-6 meters, the air extraction can be arranged on the side of the walls.

Classification of Cleanrooms

The air in cleanrooms is the criterion for determining class. The basis of standards for clean spaces is a micrometer, abbreviated micron. The number of permitted particles of 0.5 microns determines the class of clean room.

Classes 1 and 10 are used in the manufacture of electronics, such as integrated circuits. The class of purity of pharmaceutical premises 100 is used in the manufacture of medical implants and in photo laboratories. Class 10,000 is used in hospital operating rooms and television tubes. Finally, class 100,000 is used in the production of ball bearings.

Clean Zone in the Clean Room

According to ISO 14644, a clean zone is a defined area in which the quantitative concentration of airborne particles is controlled and classified, and which is designed and operated in this way to control the intake, formation and retention of contaminants inside the room.

A clean zone may be defined as a fixed space in a clean room, or it may be organized as a mobile option with the possibility of movement inside the room.

Each clean zone includes:

Clean zone may additionally be equipped with an air quality monitoring system as in cleanrooms.
