Class 10-100 clean rooms are primarily designed to rapidly carry away dust particles from the room by means of unidirectional vertical airflow, i.e., airflow within the clean room maintains uniformity of direction and velocity across the same cross-section. In order to achieve this goal, high-efficiency filters are usually spread all over the roof to ensure vertical air circulation.

For 1K-100K level of clean room, the direction of its airflow organization and 10-100 level of clean room is different. The airflow inside this type of clean room flows at an uneven speed, accompanied by reflux and vortex phenomena. It mainly relies on the continuous dilution of clean airflow to eliminate internal contamination in order to achieve the desired clean effect. The different levels of clean rooms are mainly dependent on the amount of air supplied per unit of time.

• Preparation before installation

  Before starting the installation of a clean shed, the construction area needs to be well prepared. First of all, make sure that the construction area is dry, ventilated, well lit and out of direct sunlight. At the same time, make sure that the construction area has enough space to accommodate the clean room and related equipment. In addition, prepare the necessary tools and materials for the installation, including lifting equipment, clean room materials, measuring tools, protective tools and so on.

• Installation framework

  According to the size and design requirements of the cleanroom, the frame materials are assembled in a predetermined position. Usually, the frame of the clean room is made of steel or aluminum alloy, and the verticality and horizontality of the frame should be ensured during installation to ensure the stability of the structure.

• Installation of ceiling and wall panels

  The ceiling and wall panels are usually made of purification boards or other materials that meet the cleanliness requirements. When installing, the flatness of the roof and wall panels should be ensured, and the joints should be tight to avoid any loopholes. Attention should also be paid to the FFU installation of the ceiling to ensure that the high-efficiency filters are properly installed to achieve the desired clean effect.

• Installation of air purification system and lighting system

  The interior of the clean shed should be equipped with an air purification system, including high-efficiency filters, air showers, and UV disinfection lamps. When installing, it should be ensured that the connection between the components is tight to avoid air leakage. At the same time, the interior of the clean shed should also be equipped with a lighting system, including LED lamps and lanterns, etc. When installing, it is necessary to ensure that the lamps and lanterns are waterproof, dustproof performance, as well as the uniformity of illumination.

• Installation of electrical systems

  The electrical system of the clean room should comply with relevant national standards and industry requirements. When installing, it should ensure that the power supply is stable and safe, as well as the normal operation of each electrical equipment. At the same time, grounding treatment should be carried out to ensure the safe operation of the equipment inside the clean room.

• Acceptance and debugging

  Clean shed installation is completed, acceptance should be carried out. After acceptance, the clean shed debugging to ensure that the normal operation of the system to achieve the desired clean effect. This step is very important, because only after strict debugging, clean shed can really play its due role.

• Precautions

  Throughout the installation process, there are some important precautions that need to be observed. For example, installers need to wear appropriate safety equipment, such as helmets, overalls, shoe covers and so on. If you have any questions or encounter any difficulties during the installation process, you should seek help from the technicians in a timely manner. In addition, it is also necessary to regularly inspect and maintain the clean shed, clean the filters and discharge pollutants in a timely manner to ensure that the clean shed maintains a good operating condition for a long time.

Test items for clean room

• Temperature and Humidity

  Ensure that the temperature and humidity in the clean room are controlled within specified limits so as not to interfere with the production or testing process.

• Air Suspension

  Test the concentration of airborne suspended particles in the clean room to ensure that there are no excessive particles present to safeguard the cleanliness of the production process.

• Fresh Air Volume

  Fresh air volume testing ensures that there is an adequate supply of fresh air in the clean room to maintain air quality.

• Pressure Difference

  Check whether the pressure difference between the inside and outside of the clean room complies with the regulations to ensure the isolation effect of the clean room.

• Airflow Condition

  Tests whether the airflow condition in the clean room meets the design requirements to ensure that the product manufacturing or testing process meets expectations.

• Microbial Count

  For biological clean rooms, microbial counts, including the measurement of settled bacteria and planktonic bacteria, are also required to ensure the cleanliness of the sterile environment.

Importance of Clean Room Testing

Cleanroom testing is essential to ensure product quality and productivity. Regular maintenance and monitoring not only ensures that the cleanroom achieves or maintains the required cleanliness standards, but also identifies and resolves potential problems in a timely manner, avoiding production accidents and product defects caused by contamination.
