For the 300,000-level purification project, first of all, the purification level is not very high. The smaller the clean room level, the higher the cleanliness level. According to the US federal 209E standard, a 300,000-level purification project should refer to 300,000 0.5 micron (um) dust particles per 1 cubic foot (ft?). According to China's GB/T 16292-1996 standard, the 300,000 level is 10,500,000 05um dust particles per cubic meter. Generally used in pharmaceutical factories, cosmetics and other industries.
Different areas require different clean room materials. For areas above 500㎡, it is recommended to use traditional clean room engineering. For 100-500㎡, it is recommended to use modular clean rooms. For areas below 100㎡, modular clean rooms or clean sheds can be used.
For example, in a modular clean room, there will be an aluminum profile frame/iron square tube electrostatically sprayed and painted steel plate, or a SUS304 stainless steel frame stainless steel plate, and an insulating glass window; the number of FFUs will be arranged according to the area and cleanliness level; if If the temperature and humidity are required, it can also be equipped with a small central air conditioner or a constant temperature and humidity air conditioner.
The entrance and exit are equipped with air showers, cargo showers and transfer windows. The air shower can be single, double, multi-person or tunnel air shower according to the number of people. The cargo shower can choose PVC fast rolling door, automatic sliding door, etc. The transfer window can be customized according to the size of the transferred objects, dust removal requirements, etc.
The clean room can be equipped with flat-panel LED lighting, ultraviolet germicidal lamps, yellow light, etc., clean clothing and shoe cabinets, stainless steel shoe changing stools, wind speed, dust particles, pressure difference, temperature and humidity, smoke sense, etc. kind of sensor.
The clean room is also equipped with an intelligent control system, a 10-inch touch screen, which can select working mode or duty mode. The cleanliness, temperature and humidity can be visible, and it can also provide fault alarm, remote control, permission settings, etc.
The above is the basic configuration of a modular clean room, which must be customized according to needs.
