Clean room refers to a workshop that can remove airborne particles, bacteria and other pollutants in a certain space range, and control the environmental factors affecting production such as temperature, humidity, cleanliness, pressure, airflow velocity and static electricity within a certain design requirement, and give special design.
That is, no matter how the outside air conditions change, its indoor can maintain the set cleanliness, temperature, humidity and pressure and other environmental factors required for production performance.

According to regional environment, purification degree and other factors, clean room project workshop can be a number of grades.
Generally, the smaller the value, the higher the purification level.
