Cleanroom Container
In the cleanroom container, air cleanliness is achieved by passing the air through HEPA filters. Depending on customer’s cleanroom requirements, the more often the air passes through the HEPA filters, the fewer particles are left in the room air.
Wall partitioning for airlocks spaces can be easily installed in the cleanroom container. This area is important to prevent the migration of particles from outside into the clean space.
Cleanroom classification is dependent on air changes per hour calculation. The volume of air filtered in one hour divided by the volume of the room gives the number of air changes per hour.
| ISO Class | Average number of air changes per hour |
| ISO 5 | 240–360 air changes per hour (unidirectional airflow) |
| ISO 6 | 90–180 air changes per hour |
| ISO 7 | 30–60 air changes per hour |
| ISO 8 | 10-25 air changes per hour |
| Convertional building | 2-4 air changes per hour |
* The above-suggested air changes per hour are only a design rule of thumb*
