Clean room, also known as clean room or clean room. It refers to the particulates, harmful air, bacteria and other pollutants in the air within a certain space range, and the indoor temperature, cleanliness, indoor pressure, airflow speed and airflow distribution, noise and vibration and lighting, static electricity control within a certain demand range, and to give a specially designed room. That is, no matter how the external air conditions change, the indoor can maintain the original set requirements of cleanliness, temperature and humidity and pressure performance characteristics.

A clean room is a controlled environment with low levels of pollution from sources such as dust, airborne microorganisms, suspended particles, and chemical volatile gases. Cleanrooms have a controlled pollution level, which can be determined by the number of particles per cubic meter of space, or by the maximum particle size.

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: to control the pollution of living particles (bacteria) and inanimate particles (dust) to work objects. It can also be divided into:

A. General biological clean room, mainly to control the contamination of microbial (bacterial) objects. At the same time, the internal material should be able to withstand the erosion of various sterilizers, and the internal pressure is generally maintained. In essence, its internal materials should be able to withstand a variety of sterilization treatment of industrial clean room.

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
