Building an efficient Cleanroom System requires proper consideration of 'cleanliness' alongside airflow management as well as material choices and equipment positioning.

A Clean Room is a room in which the concentration of suspended particles in the air is controlled. It should be constructed and used to minimize the introduction, generation and retention of particles in the room. Other relevant parameters such as temperature, humidity, pressure, etc. are required to be controlled. Air cleanliness refers to the extent of the amount of dust particles in the air in a clean environment, high dust concentration is low cleanliness, low dust concentration is high cleanliness.

Clean Room is a special type of environmental control in which factors such as the number of particles in the air, humidity, temperature, and static electricity can be controlled to achieve specific cleanliness standards. Clean rooms are widely used in high-tech industries such as semiconductor, electronics, pharmaceutical, aviation, aerospace, and biomedical.

Class C bioengineering Cleanroom is a clean level in the field of bioengineering based on air cleanliness, air pressure, air volume, temperature and humidity, noise, microbial content and other indicators. It is mainly used for clean operation areas of lower importance in the process of producing sterile drugs, such as the preliminary processing of cell culture, genetic testing and other links.
