Clean room classification by use (can be divided into two categories)

Industrial clean room

For the control of inanimate particles. It mainly controls the pollution of air dust particles to work objects, and generally maintains positive pressure inside. It is suitable for precision machinery industry, electronic industry (semiconductor, integrated circuit, etc.) aerospace industry, high purity chemical industry, atomic energy industry, optical magnetic products industry (CD, film, tape production) LCD (liquid crystal glass), computer hard disk, computer magnetic head production and other industries.

Biological clean room

It mainly controls the pollution of living particles (bacteria) and inanimate particles (dust) to working objects. Can also be divided into;

A. General biological clean room: mainly control the contamination of microbial (bacterial) objects. At the same time, its internal materials should be able to withstand the erosion of various sterilizers, and the internal pressure is generally guaranteed. In essence, its internal materials should be able to withstand a variety of sterilization treatment of industrial clean room. Example: pharmaceutical industry, hospital (operating room, aseptic ward) food, cosmetics, beverage production, animal laboratory, physical and chemical laboratory, blood station, etc.

B. Biological safety clean room: mainly control the pollution of living particles to the outside world and people. The interior should maintain negative pressure with the atmosphere. Examples: bacteriology, biology, clean laboratory, physical engineering (recombinant gene, vaccine preparation)
