I. Different Definitions
1.A clean booth, also known as a clean work booth (dust - free booth, purification booth, operation workbench, etc.), refers to a small space enclosed by an anti - static grid curtain or plexiglass within a clean room. Above it, a HEPA (High - Efficiency Particulate Air) filter and an FFU (Fan Filter Unit) air - supply unit are used to form a space with a relatively higher purification level than the clean room. A clean booth can be equipped with purification equipment such as air showers and pass - through windows.
2.A clean room is a specially designed room where pollutants such as microparticles, harmful air, and bacteria in the air within a certain space range are removed. Moreover, the indoor temperature, cleanliness, indoor pressure, air - flow velocity and distribution, noise, vibration, lighting, and electrostatic control are maintained within a specific required range. That is, regardless of how the external air conditions change, the indoor environment can always maintain the originally set cleanliness, temperature, humidity, pressure, and other performance characteristics. The main function of a clean room is to control the cleanliness and temperature - humidity of the atmosphere that products come into contact with, enabling products to be produced and manufactured in a favorable environmental space. Such a space is called a clean room.
II. Material Comparison
1.The frames of clean booths generally come in three types: stainless - steel square tubes, painted iron square tubes, and industrial aluminum profiles. The top can be made of materials such as stainless - steel sheets, painted cold - plastic steel sheets, anti - static grid curtains, and acrylic plexiglass. The surroundings usually use anti - static grid curtains or plexiglass, and the air - supply part uniformly adopts FFU clean air - supply units.
2.Clean rooms generally use foam - colored steel or rock - wool board for ceiling and side - wall construction. They have an independent air - conditioning air - supply system. The air goes through three - stage filtration of primary, medium - effect, and high - efficiency filters. Personnel and materials are equipped with air showers and pass - through windows for clean filtration.
III. Cost Comparison between Clean Booths and Clean Rooms
1.Clean booths are usually built within clean rooms. Therefore, there is no need to consider air showers, pass - through windows, and air - conditioning air - supply systems, and the cost is significantly lower compared to clean rooms. Of course, this is related to the materials, size, and cleanliness level of the clean booth. Some clean booths are built within clean rooms, but some customers do not want to build a separate clean room. Without considering purification equipment such as air - conditioning systems, air showers, and pass - through windows, the cost of a clean booth is approximately 40% - 60% of the cost of a clean room. This depends on the customer's choice of clean - booth materials and the size of the clean booth. The larger the area that needs to be cleaned, the smaller the cost difference between the clean booth and the clean room.
IV. Advantages and Disadvantages
1.For clean booths:
1.A) Fast construction, low cost, convenient for disassembly and assembly, and reusable.
2.B) Since the height of a clean booth is usually around 2 meters, if a large number of FFUs are used, the internal noise of the clean booth will be high.
3.C) Without an independent air - conditioning air - supply system, the inside of the clean booth often feels stuffy.
4.D) If a clean booth is not built within a clean room, due to the lack of medium - effect air - filter filtration, the lifespan of the high - efficiency filter is relatively shorter compared to that in a clean room. Frequent replacement of high - efficiency filters will increase costs.
2.For clean rooms:
1.A) Slow construction and relatively high cost.
2.B) The height of a clean room is usually around 2,600 mm, and workers do not feel oppressed when working inside.
