Cleanrooms are essential in industries requiring stringent control of particulates, microorganisms, and contaminants. Their primary role is to create an uncontaminated environment for manufacturing, research, or experimental processes.

1. Electronic information industry
This is a prominent application for cleanrooms, demanding exceptionally high air purity.
Semiconductor manufacturing: Core processes such as photolithography and etching in chip production need to control particles at the micrometer or even nanometer level; otherwise, it will lead to the scrapping of the chip.
The manufacture and assembly of integrated circuits, sensors, precision resistors, and capacitors must minimize dust to preserve product performance and longevity.
Display manufacturing: The production process of OLED, LCD and other display screens, especially flexible screens, has strict requirements for the temperature, humidity and cleanliness of the environment.
2. The field of medicine and life sciences
It is directly related to the safety of drugs and the accuracy of experiments, and is a key application scenario of cleanrooms.
Pharmaceutical production: The preparation, filling, freeze-drying and other processes of sterile drugs (such as injections and vaccines) must be carried out in a sterile clean room to prevent microbial contamination.
Medical devices: The production and packaging of precision medical devices such as artificial joints, heart stents, and contact lenses require the control of particles and microorganisms to ensure safe use.
Biological laboratories: Biopharmaceutical research and development, cell culture, genetic engineering experiments, etc., require a clean environment to avoid cross-contamination and ensure the reliability of experimental results.
3. Food and cosmetics industry
It is mainly used to ensure the hygiene and safety of products, extend their shelf life and prevent the breeding of microorganisms.
Food processing: For foods with high cleanliness requirements, such as aseptic filled beverages, ready-to-eat foods, health foods, etc., the total number of bacteria in the production environment needs to be controlled through clean rooms.
Cosmetics production: The production of high-end skin care products and makeup, especially liquid products, needs to prevent dust and microbial contamination to avoid product deterioration or skin problems.
4. Precision Manufacturing and aerospace
For the production and inspection of high-precision products, it is necessary to avoid the influence of environmental factors on product accuracy.
Precision instruments: The manufacturing and calibration of optical instruments (such as lenses, telescopes) and measuring instruments (such as micrometers, laser measuring equipment) require the control of particles to ensure accuracy.
Aerospace: The production and assembly of aircraft engine components, satellite assemblies, etc., have extremely high requirements for cleanliness and environmental stability, and it is necessary to prevent tiny impurities from affecting the safe operation of equipment.
