The grade of modular clean room is usually determined by many factors, the most important of which include industry demand, clean room equipment requirements and product process. Different application scenarios have different requirements for clean rooms, so it is necessary to determine the appropriate clean room grade according to the actual situation.
Industries involving clean rooms
1. Pharmaceutical industry
The pharmaceutical industry has extremely high requirements for clean rooms, especially when producing sterile drugs or vaccines. In order to prevent bacterial and particulate contamination, ISO 5 standards are usually required. ISO 5 requires that the number of 0.5 micron particles per cubic meter of air shall not exceed 3520 to ensure the purity and safety of the product.
2. Electronics industry
The requirements for cleanliness in the production process of electronic products are also very strict, especially for precision parts such as semiconductors and display screens. Clean rooms in the electronics industry are generally required to reach ISO 6 or ISO 7. The requirement for ISO 6 clean rooms is that the content of particles of 0.5 microns and above per cubic meter does not exceed 35,200 to prevent tiny dust from affecting product performance.
3. New Energy Industry
The new energy sector, especially the production of solar panels and lithium batteries, has certain requirements for clean environments. ISO Class 7 clean rooms are more common in this industry, with a particle count limit of no more than 352,000 particles larger than 0.5 microns per cubic meter, which helps improve battery efficiency and life.
4. Semiconductor Industry
The semiconductor manufacturing process has very high requirements for environmental cleanliness and usually requires ISO Class 5 or higher clean rooms. This is because particulate contamination can directly affect the performance of integrated circuits. ISO Class 5 clean rooms stipulate that the number of particles larger than 0.5 microns per cubic meter of air shall not exceed 3,520.
5. Food Industry
Although food production does not have as strict cleanliness requirements as the pharmaceutical and electronics industries, ISO Class 8 clean rooms are a more common standard that can avoid contamination sources such as bacteria and mold. ISO Class 8 clean rooms stipulate that the number of particles larger than 0.5 microns per cubic meter of air shall not exceed 3.52 million.
