Cleanroom environmental control has been widely applied in the production of industrial products across various industries, as well as in environments requiring particle and microbial contamination prevention. Due to the unique product characteristics and varying production processes in each industry, the requirements for environmental control content and standards differ. The content of cleanroom environmental control should include air purification, clean construction, control of pollutants in water, gases, or chemicals that come into direct contact with products, as well as in production equipment and tools. It also encompasses the control and prevention of micro-vibrations, noise, and static electricity. Therefore, the design of a cleanroom not only requires air purification to meet specified cleanliness levels but also necessitates preventing contamination caused by inappropriate construction materials and decorative methods. Some cleanrooms also require the supply of pure water, ultra-pure gases, and highly pure chemicals.
