Dustless workshop class 5 clean shed - anti-static, acrylic, stainless steel, AC fan
Class 5 Clean Room
Class 5 clean rooms are designed for the manufacture of high-precision products such as semiconductor chips and optical components, which require extremely high levels of cleanliness. The number of particles greater than or equal to 0.5 microns per cubic meter of air must not exceed 3,520, and there are more stringent standards for smaller particles, such as 0.1 microns. Class 100 clean booths usually use highly efficient air filtration systems and air shower technology to ensure the cleanliness of the air. In addition, the control of incoming and outgoing personnel and goods is also very strict to avoid any form of contamination and cross contamination.
Class 6 Clean Room
Class 6 clean rooms have cleanliness requirements slightly lower than Class 5 and are suitable for manufacturing and processing where product quality is required but less stringent. The number of particles greater than or equal to 0.5 micron particle size per cubic meter of air shall not exceed 35,200, and for 0.1 micron particles, there are also corresponding regulations. Class 6 clean booths also require the use of highly efficient air filtration technology and positive pressure control systems to maintain cleanliness.
Class 7 Clean Room
Class 7 clean rooms have relatively low cleanliness requirements and are typically used for manufacturing and processing where product quality requirements are less stringent. The number of particles greater than or equal to 0.5 micron particle size per cubic meter of air must not exceed 352,000. Class 7 clean room can use relatively simple air purification technology, such as ordinary filters and ventilation. Nevertheless, it is still necessary to maintain a certain degree of cleanliness and hygienic environment, and the management and control of incoming and outgoing personnel and goods also need to maintain a certain level of standardization.

Working principle of clean room
The core component of the clean room is the fan filtration unit (FFU), which is responsible for sucking in the outside air and purifying it through the primary and high efficiency filters. The purified air is sent out uniformly from the air outlet at a certain wind speed (usually 0.5m/s±20%) to form a uniform flow layer, making the clean air flow vertically in one direction to ensure that the cleanliness of the working area reaches the predetermined standard.
Structural Characteristics of Clean Room
The design of a clean room is usually modular, which makes it easy to install and expand in the future. Its frame can be made of sturdy materials such as industrial aluminum or stainless steel squares, and the surface is usually sprayed to prevent rust and corrosion. The surrounding area is commonly used with anti-static drapes or acrylic panels for good anti-static effect and high transparency. The internal purification level can range from class 100 to class 10,000, which is suitable for areas with different purification requirements.
