Laboratory Class 6 Clean Shed-Non-anti-static, Acrylic, Stainless Steel, AC Fans
Air changes
The number of air changes is a very important parameter in a clean room, which determines the frequency of air renewal in the clean room. The specific value depends on the cleanliness level of the clean room, for example, 7 class clean room air change times should not be less than 20 times, while the 6 class requires a higher number of air changes, at least 30 times. The number of air changes directly affects the cleanliness inside the clean room, so it is an important indicator for evaluating the performance of the clean room.
Differential pressure
Differential pressure refers to the pressure difference between the clean room and its neighboring areas, this parameter ensures that the gas inside the clean room will not flow to the outside world, thus avoiding the intrusion of pollutants. In general, the pressure difference between the main workshop and the neighboring rooms should be maintained above 5Pa.
Average wind speed
Average wind speed is an important parameter to measure the speed of air flow inside the clean room. In class 10 and class 100 clean room, the average wind speed is usually controlled between 3-0.5m/s. The proper wind speed is not only effective, it is also important for the air flow. Proper air velocity not only effectively conveys and distributes air, but also reduces the accumulation of dust particles and maintains the cleanliness inside the clean room.

Working Principle
The working principle of the clean room is based on air filtration and flow control. The fan is located at the top of the clean room and is responsible for drawing air in and passing it through a primary filter for initial filtration to remove larger particles. Subsequently, the air is further purified by a high-efficiency filter, which removes even finer particles, and finally it is delivered uniformly at a certain air speed, forming a homogenous layer that ensures a vertical unidirectional flow of clean air, thus maintaining the cleanliness of the work area.
Structural Characteristics
The clean room is usually designed as an assembled structure with a solid and beautiful frame that does not rust or produce dust. Antistatic curtains or toughened glass are usually used on the periphery to achieve 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 that require localized high cleanliness, such as assembly line operation areas or high-precision product assembly areas.
