The main body of a modular cleaning room is mainly composed of a frame, steel plates, glass windows, FFUs, high-efficiency air supply outlets, steel air return outlets, and LED touch panels. The core and most important part is the FFU. FFU is fully known as a fan filter unit, which is a modular end air supply device with its own power and filtering effect, and is equipped with a primary and efficient two-stage filter screen. After powering on, the fan starts to work, inhales air from the top of the FFU and passes through primary and high efficiency filters to filter, sending clean air through the high efficiency air supply outlet.

Many products have extremely high environmental requirements during the production process, such as precision electronic components, and the fine dust particles in the air have a significant impact on product quality. The modular clean room actually sends clean air to dilute the indoor air, and then discharges the pollution through the steel return air port. These winds will again come to the top of the FFU, be sucked in by the FFU, filtered, and then returned to the room, forming an air circulation. Different products have different requirements for cleanliness levels, which are achieved through different air supply efficiencies. That is, the more FFUs, the higher the cleanliness level.

It should be noted that the above cleanliness level refers to the fact that under static indoor conditions, dust particles in the air will stabilize within a fixed range. However, in actual production, the calculation of the cleanliness level also takes into account the dust generated during personnel movement and equipment operation. Generally, the cleanliness level of a modular clean room should be greater than the level required.

The working principle of a modular clean room is the circulation and filtration of air. During the circulation process, clean air is allowed to fill the entire clean room to achieve the cleanliness level required for production operations. Other components of the modular clean room also play an indispensable role in this process, with a 10-inch touch panel that intelligently controls the wind speed; The clean door and window dispensing process increases the airtightness of indoor air; Double tempered glass windows allow real-time monitoring of indoor conditions. The combination of all the above accessories enables the modular clean room to have a strong purification ability, enabling the air to reach the required cleanliness level.
