• Frame Material

  The frame of the clean shed is usually made of industrial aluminum profiles, stainless steel squares or iron squares sprayed with plastic, and these materials are characterized by solidity, beauty, no rust and no dust production. Aluminum profiles are widely used because of their light weight, easy processing, and good thermal conductivity. Stainless steel square passes, on the other hand, are preferred for their excellent corrosion resistance and mechanical properties. Sprayed iron squares provide a good protective layer while ensuring strength and reducing the possibility of rust.

• Wall Material

  Antistatic drapes or acrylic panels are often used for the walls of clean rooms. The common characteristics of these materials are good anti-static effect and high transparency, which can effectively prevent the intrusion of dust and microorganisms, while maintaining high visibility and facilitating the monitoring of the internal work situation.

• FFU Material

  FFU (Fan Filter Unit) is a key component of the clean room, which is responsible for inhaling and purifying the air through the high-efficiency filtration system, and then uniformly sending it into the clean area with a certain wind speed.FFU usually adopts centrifugal fans, which are characterized by long life, low noise, maintenance-free, small vibration, and can be adjusted by infinitely variable speeds in order to adapt to the different requirements of cleanliness.

• Other materials

  The top sealing plate of the clean room can be made of anti-static curtain, aluminum plate or cold plate baking paint, etc. The interior can also be equipped with purified lighting system to ensure that a certain working environment can be maintained even when the external light source is turned off.

• Structural composition

  The clean shed is mainly composed of box, fan, primary air filter, high-efficiency filter, damping layer, lamps and so on, and the shell is usually treated with plastic spraying process. It can be suspended or ground support, compact structure, easy to use. In addition, the clean room can also be used individually or connected to form a strip clean area to adapt to different cleanliness requirements and space layout.

• Materials and Construction

  Frame materials for cleanrooms typically include industrial aluminum, stainless steel or spray-plasticized iron squares to ensure a sturdy and aesthetically pleasing structure, while also preventing rust and dust production. Anti-static drapes or tempered glass are used around the perimeter to provide good anti-static effect and high transparency. The fan filter unit (FFU) is responsible for air supply, and the internal purification level can reach class 100-100K, which is especially suitable for localized areas that require high cleanliness, such as assembly line operation areas.

• Characteristic Advantages

  The clean room is characterized by its modular structure, which makes it easy to improve the cleanliness level, and has strong expandability and reusability value. In addition, the clean room is highly mobile and can be fitted with gimbals for easy positional adjustment and movement. Compared with the traditional civil engineering or assembly type Class 100 clean room, the clean room investment is less, the effect is quick, easy to install, and the operation cost is low.

• Applications

  Clean rooms are widely used in various fields, such as the assembly line operation area in electronic factories, the packaging process in food factories, and scientific research units in laboratories. On these occasions, the clean room can provide a clean environment that meets specific requirements, thus improving product quality and research accuracy.

• Installation Advantages

  The installation of clean shed has many advantages. First of all, it can be used individually or in combination, and compared with the traditional 100-level clean shed, it has less investment, quick results, easy installation and low operating costs. Secondly, due to its modular structure, the cleanliness of the shed is easy to improve, scalability, and has a high reuse value. Furthermore, the clean room is easy to move, and can even be installed with universal wheels to facilitate future transfer and adjustment.

• Installation Requirements

  When installing a clean room, a series of strict requirements need to be observed. The first is the choice of installation location, clean shed should be installed in a dry, ventilated, well-lit environment, avoid direct sunlight, and according to special industry requirements to meet such as anti-static, anti-corrosion and other conditions. Second is the foundation construction, must meet the design requirements to ensure that the foundation is level, solid, level, and through the acceptance before the subsequent installation.

• Installation steps

  The installation steps of the clean shed involves a number of aspects. The first is the installation of the frame, you need to ensure that the verticality and level of the frame, and anti-corrosion, rust treatment. The next step is the installation of the roof and wall panels, which should be made of purification boards or other materials that meet the cleanliness requirements, and ensure their flatness and tight seams. This is followed by the installation of the air purification system, including high-efficiency filters, air showers, ultraviolet disinfection lamps, and so on, to ensure that the connection between the components is tight and air leakage is avoided. The installation of the lighting system needs to ensure the waterproof and dustproof performance of the lamps and the uniformity of illumination. The installation of the electrical system should comply with national standards and industry requirements to ensure that the power supply is stable and safe. Finally, grounding treatment to ensure the safe operation of the equipment inside the clean room, and acceptance and debugging after the completion of the installation to ensure the normal operation of the system to achieve the desired clean effect.

Clean room testing program

• Temperature and humidity: Test whether the temperature and humidity in the clean shed meet the production requirements to ensure the stability and reliability of production.

• Air Suspension: Ensure the cleanliness inside the clean shed by collecting air samples and testing the number of suspended particles in them.

• Fresh air volume: Fresh air volume directly affects the maintenance of air quality inside the clean room, and needs to be tested regularly to see if it meets the standard.

• Pressure difference: Detect the pressure difference between the inside and outside of the clean room as well as between different clean level areas to ensure that the airflow is in the right direction and to prevent cross-contamination.

• Airflow status: Evaluate whether the airflow organization is reasonable, and whether it can effectively dilute and eliminate pollutants.

• Microbial count: Detect the microbial count in the clean room, especially planktonic bacteria and settled bacteria, to ensure the establishment of a sterile environment.

• Surface contamination degree: through the detection of the surface in the clean room, assess its cleanliness and prevent the surface from becoming a source of contamination.
