What is a clean room

Clean room: also known as dust-free workshop, also known as dust-free room, mainly composed of air shower door, air supply filter, exhaust filter device, etc.

1, the function is to control the pollution of particles. In order to achieve the specified cleanliness level, effectively control the pollution of particles, so that people are engaged in precision production and scientific experiment activities, clean room is not limited to "clean", and must be a multifunctional complex of cold and heat, noise, illumination, static electricity, micro vibration have considerable requirements, Is a collection of architectural decoration, air conditioning purification, pure water and pure gas, electrical control and other professional technology in one product

2. The main feature is to let the waste gas in the workshop be discharged in time through the exhaust filter device, and then the fresh space outside is filtered into the workshop through the air supply filter for many times. According to the principle of positive and negative pressure of air, the workshop is clean and dust-free. Give everyone a good working environment.

3. Principle:

Air flow → primary purification → air conditioning → medium purification → fan air supply pipe → high efficiency purification tuyere → Blow into the room → take away dust, bacteria and other particles → return air shutter → primary purification repeat the above process to achieve the purpose of purification.

4, according to the use can be divided into two categories:

(1) Industrial clean room - to inanimate particles as the control object. It mainly controls the pollution of inanimate particles to the working object, and maintains positive internal pressure. It is suitable for precision industry, electronics industry, aerospace industry, atomic energy industry, printing industry, photographic industry and other sectors.

(2) Biological clean room -- with living particles as the control object, which can be divided into:

① General biological clean room. It mainly controls the pollution of living particles to working objects. At the same time, the internal material should be subjected to a variety of sterilization agent erosion, and the internal pressure is generally maintained. It can be used in pharmaceutical industry, food industry, medical facilities, experimental facilities and so on.

② Biosafety clean room. The main control object of life particles to the outside and human pollution, the internal need to maintain negative pressure. Used in experimental facilities, biological engineering, medical facilities, etc.
