The production of electronic optics (semiconductor, PCB, chips, wafers, cameras, optical lenses, LCD, OLED, liquid crystal, display device FED, polycrystalline silicon, etc.) of the workshop environment requirements are very strict, the manufacturing process is different, part of the area of the cleanliness requirements are also different, usually to the class 10, class 100, class 1000, class 10000, class 100000 level as the standard.

In Cleanrooms, Operating Rooms, Laboratories and other environments with high requirements for air cleanliness, CFD airflow organisation is one of the key factors in controlling cleanliness. Through reasonable airflow organisation design, airborne particles, microorganisms and other pollutants can be effectively controlled to ensure that the environment meets the required cleanliness standards.

In the automotive industry, ensuring high-quality manufacturing standards is crucial for both performance and safety.

As an important product of clean air technology, Cleanrooms have the following three characteristics. 1. The Clean Room is the air cleanliness of a certain level of space for people's activities, its function is to control dust particles and microbial contamination.  2. Tthe Clean Room is a multi-functional complex, requires the cooperation of a number of professional, such as construction, process piping and drainage, electrical professional, and most importantly, HVAC professional. 3. Evaluation of the quality of a Clean Room Design, construction and operation management are very important, Clean Room is through the design to construction, from construction to operation of the whole process to reflect, any one of the links to the problem, will affect the important indicators of the Clean Room.
