• Clean shed frame material

The frame of the cleanroom shed is usually made of industrial aluminum profiles, stainless steel squares or iron squares with multi-layer pickling and electrostatic spraying, all of these materials have good corrosion and rust resistance, and at the same time, they also guarantee the beauty and generosity of the cleanroom shed. For example, the 40 series of clean shed frames, with dimensions of 4040mm, provide sufficient stability. In addition, there is also the 4545W model with dimensions of 4545mm, again designed to accommodate different usage requirements.

• Cleanroom Panel Materials

Cleanroom panels are made of cold rolled steel (A3) and stainless steel (SUS201, SUS304, SUS316, etc.), with a thickness of 0.8~1.5mm, which not only ensures the structural integrity of the cleanroom, but also takes into account its durability and practicality.

• Other components of the clean room

In addition to the above materials, the clean room also includes components such as FFU fan filtration units, primary filters, and high efficiency filters. the FFU laminar flow hood is responsible for providing a constant and stable flow of clean air, while the filters ensure the purity of air. In addition, the clean room can be surrounded by optional materials such as drapes or glass to meet specific protection needs.

• Structural composition

A clean room is usually composed of a box, a fan, a primary air filter, a high efficiency filter, a damping layer, a light fixture, etc., and the outer shell is usually treated with a plastic spraying process. The compactness and practicality of this structure allows the clean room to be easily hung or supported from the ground, and it is also easy to be used individually or connected to form a strip clean area.

• Functional Features

The core function of a clean room is its highly efficient air filtration system, which effectively removes airborne contaminants such as dust and microorganisms, ensuring that the air is as clean as it needs to be. In addition, the design of the clean room allows for the formation of a uniform airflow within the room, typically at an air velocity of 0.45m/s ± 20% to maintain a vertical unidirectional flow to minimize contaminant build-up.

• Application Areas

Clean booths are widely used in many industries due to their flexibility and ease of installation. In the electronics manufacturing industry, clean booths protect sensitive components from dust contamination; in the pharmaceutical industry, clean booths ensure the sterile production of medicines; and in the food processing industry, clean booths are used to maintain hygienic standards in the food production environment. In addition, clean rooms also play an important role in research and laboratory environments, providing a clean environment suitable for precise experimental research.

• Benefits and Challenges

Significant advantages of clean rooms include their rapid installation, low investment and operating costs, and high degree of mobility and reusability. However, despite the many benefits offered by clean rooms, there are still many challenges in their construction and operation, especially in terms of management and maintenance, which require significant investment in human and material resources. In addition, as technology develops and industry standards improve, the design and performance of cleanrooms are evolving to meet higher standards of cleanliness.

• Construction preparation: Before installation, the installation site needs to be surveyed to ensure that the environment is dry, ventilated, well lit and meets specific industry requirements, such as anti-static and anti-corrosion.

• Foundation construction: Foundation construction should meet the design requirements to ensure that the foundation is level, solid and horizontal. Acceptance inspection should be carried out after construction, and the installation of clean shed can be carried out only after passing.

• Frame Installation: The frame of the clean shed is usually made of steel, and the verticality and horizontality of the frame should be ensured during the installation, as well as anti-corrosion and anti-rust treatment.

• Installation of roof and wall plate: The roof and wall plate should be made of purification board or other materials that meet the clean requirements. When installing, ensure their flatness and tight seams to avoid loopholes.

• Air purification system installation: The interior of the clean shed should be equipped with a highly efficient air purification system, including high-efficiency filters, air showers, ultraviolet disinfection lamps and so on. When installing, make sure the connection between components is tight to avoid air leakage.

• Lighting system installation: the clean shed should be equipped with lighting systems inside, such as LED lamps and lanterns. When installing, make sure the waterproof and dustproof performance of the lamps and lanterns, as well as the uniformity of illumination.

• Electrical system installation: the electrical system of the clean room should meet the relevant national standards and industry requirements. Installation, to ensure that the power supply is stable, safe, and the normal operation of the electrical equipment.

• Grounding: The grounding of the clean shed should meet the design requirements to ensure the safe operation of the equipment inside the clean shed.

• 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.

• Testing Standards

The testing of clean room is based on a series of national and international standards, such as ISO 14644, GB/T 25915.3-2024, etc. These standards specify the testing methods and requirements of clean room in detail.

• Testing items

The testing items of clean room mainly include but not limited to wind speed, air volume, temperature and humidity, differential pressure, suspended particles, planktonic bacteria, settled bacteria, noise, illumination and so on. These parameters work together in the cleanliness of the clean room, and deviation in any one of them may lead to the failure of the whole system.

• Inspection Process

The testing process usually includes a preparation phase, an implementation phase and a reporting phase. The preparation phase is mainly to calibrate and debug the testing equipment to ensure the accuracy of the testing data. The implementation phase involves performing specific inspection tasks and recording the parameters. The reporting phase involves analyzing and evaluating the test results to produce a formal test report.
