The main components of the purification project have six major parts, respectively: ground system, air duct system, automatic control system, electrical system, water supply and drainage system, and air filtration system.

As the Clean Room is a controlled area with more stringent environmental requirements, the materials that meet the requirements of clean room decoration should firstly meet the characteristics of wall, ceiling and floor without dust production, dust accumulation, corrosion resistance, easy to clean, no joints or fewer joints, and the clean room should be less dead ends and more rounded corners.

Air shower room is a kind of local purification equipment with strong generality, installed between Clean Room and non-clean room. When people and goods to enter the clean area need to be blown through the air shower room, the clean air blown out can remove the dust carried by people and goods, can effectively block or reduce the dust source into the clean area. The front and rear doors of the air shower room/goods shower room are electronically interlocked, which can also play the role of an airlock to prevent unpurified air from entering the clean area.

The four Clean Room Levels are “Class 100, Class 1000, Class 10000, Class 100000” which relate to ISO5, ISO6, ISO7 and ISO8 levels. Production facilities and biomedical laboratories need the maximum particle count standards, and filtration systems outlined by these categories for maintaining clear air environments.
