1. Different definitions
①Clean booth, also known as clean room booth, clean room tent,etc refers to a small space surrounded by anti-static PVC curtains or acrylic glass in clean room, and HEPA and FFU air supply units are used above to form a space with a higher cleanliness level than clean room. The clean booth can be equipped with air shower, pass box and other purification equipment.
②Clean room refers to a specially designed room that removes pollutants such as microparticles, harmful air, bacteria, etc. in the air within a certain space, and controls the indoor temperature, cleanliness, indoor pressure, air flow speed and air flow distribution, noise vibration, lighting, and static electricity within a certain required range. That is to say, no matter how the external air conditions change, the indoor room can maintain the characteristics of the cleanliness, temperature, humidity and pressure and other performances originally set. The main function of the clean room is to control the cleanliness, temperature and humidity of the atmosphere that the product contacts, so that the product can be produced and manufactured in a good environment space. We call such a space a clean room.
2. Material comparison
①Clean booth frames can generally be divided into three types: stainless steel square tubes, painted iron square tubes and industrial aluminum profiles. The top and can be made of stainless steel plates, painted cold plastic steel plates, anti-static mesh curtains and acrylic glass. Anti-static PVC curtains or acrylic glass are generally used around, and FFU clean air supply units are used in air supply department.
②Clean rooms generally use powder coated ceilings with vertical walls, independent air conditioning and air supply systems, and the air is filtered through primary, secondary and hepa filters. Personnel and materials are equipped with air shower and pass box for clean filtration.
3. Selection of cleanliness level
More customers will choose a class 1000 clean booth or a class 10000 clean booth, and a small number of customers will choose a class 100 or class 10000 clean booth. In short, the choice of clean booth cleanliness level depends on the customer's needs, but because the clean booth is relatively closed, if a lower level of clean booth is selected, it will often bring some side effects: insufficient cooling, employees will feel stuffy in the clean booth, so in the actual communication process with customers, you need to pay attention to this point.
4. Cost comparison between clean booth and clean room
Clean booth is usually built in clean room, so there is no need to consider air shower, pass box and air conditioning system. The cost will be greatly reduced compared with clean room. Of course, this has something to do with the materials, size and clean level required for clean booth. Clean booth will be built in clean room, but some customers do not want to build a clean room separately. If the clean booth does not consider air conditioning system, air shower, pass box and other purification equipment, the cost of clean booth is about 40%~60% of the cost of clean room, which depends on the customer's choice of clean booth materials and the size of clean booth. The larger the area that needs to be cleaned, the smaller the difference in cost between clean booth and clean room will be.
5. Pros and Cons
①Clean booths are fast to construct, low in cost, easy to disassemble and reusable; since clean booths are usually about 2 meters high, if a large number of FFUs are used, the noise inside the clean booth will be loud; since there is no independent air conditioning and air supply system, the inside of the clean booth often feels stuffy; if the clean booth is not built in a clean room, the life of the hepa filter will be shortened relative to the clean room due to the lack of filtering by the medium air filter, so frequent replacement of hepa filters will increase costs.
②Clean room construction is slow and the cost is high; clean rooms are usually about 2600mm high, and staff will not feel depressed when working in them.
