• Main frame material

  The main frame of a cleanroom shed is usually made of industrial aluminum profiles or stainless steel squares, which offer good strength and rigidity, as well as ease of cleaning and maintenance. Aluminum profiles are ideal for constructing clean booths due to their lightweight, high strength, and corrosion resistance. In addition, aluminum profiles do not require welding, which helps to reduce dust buildup at the joints and maintain a high level of cleanliness. Stainless steel squares, on the other hand, are also suitable for the construction of clean booths due to their excellent corrosion resistance and aesthetic appeal.

• Enclosure Materials

  Enclosure materials for clean rooms include, but are not limited to, Plexiglas, aluminum composite panels, aluminum alloy panels, etc. These materials not only provide good protection, but also provide a good barrier to dust. These materials not only provide good protection, but also maintain structural integrity while allowing light to penetrate and providing a bright working environment. The use of anti-static materials, such as anti-static door curtains and anti-static drapes, helps to minimize static buildup, which is especially important for certain sensitive electronics.

• Filtration Systems

  An efficient filtration system is essential to maintain cleanliness in a clean room. the FFU (Fan Filter Unit) is an important part of a clean room and is responsible for providing a continuous flow of filtered air. the FFU is usually equipped with a High Efficiency Particulate Air (HEPA) filter, which traps fine particles in the air and ensures the quality of the air. the FFU can be used for a wide range of applications, including industrial, commercial, and industrial applications.

• Other Components

  Other components of a clean room include lighting systems, control systems, circuit interfaces, and more. These components need to be carefully designed to ensure that the entire system works in harmony and takes into account the need for ease of operation and maintenance. For example, lighting may be arranged at the top of the clean room to provide an adequate light source, while the control system needs to be able to regulate the air speed of the FFUs and the brightness of the lights, etc.

Structural Features

• Assembled design: Cleanrooms are usually designed to be assembled for quick erection and disassembly, and can be resized and configured as needed.

• Modularization: The modular design of the cleanroom makes it easy to add or subtract modules to accommodate different cleanliness requirements.

• Air circulation: The cleanroom is equipped with specific air circulation paths inside, such as unidirectional (laminar) or multi-directional turbulent flow, to achieve the required cleanliness level.

• Material Selection: The material selection of the clean room takes into account the factors of dustproof, anti-static and easy to clean, and the commonly used materials include stainless steel, aluminum alloy, tempered glass and so on.

• Control system: The clean room is equipped with advanced control system, which can realize the precise regulation and control of air flow, temperature and humidity.

Applications and Advantages

Clean rooms are widely used in the electronics, pharmaceutical, medical device, food and other industries where maintaining high standards of cleanliness is critical to product quality and performance. The advantage of a clean room is that it provides a flexible, cost-effective solution for clean environments, especially for localized cleanliness improvement.

• Construction preparation: Before installation, it is necessary to survey the installation site, develop a detailed construction program, and prepare the required materials and equipment. At the same time, the construction personnel should be trained and assessed to ensure that they have the appropriate skills and qualities.

• Foundation construction: Make sure the foundation construction meets the design requirements, and the foundation must be level, solid and horizontal. After construction, acceptance should be carried out, qualified before the installation of clean shed.

• 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 installation. After the installation of the frame is completed, anti-corrosion and anti-rust treatment should be carried out.

• 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, the flatness of the roof and wall plate should be ensured, and the joints should be tight to avoid loopholes.

• Installation of air purification system: The interior of the clean shed should be equipped with an air purification system, including high-efficiency filters, air showers, ultraviolet disinfection lamps and so on. When installing, it should be ensured that the connection between each component is tight to avoid air leakage.

• Lighting system installation: the clean room should be equipped with lighting system, including LED lamps and lanterns. When installing, the waterproof and dustproof performance of the lamps and lanterns, as well as the uniformity of illumination should be ensured.

• Electrical system installation: the electrical system of the clean room should comply with the relevant national standards and industry requirements. Installation should 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.

Cleanliness Standards

• ISO 14644: This is an international standard that defines cleanliness classes for cleanrooms.The ISO 14644-1 standard specifies particle count limits for various cleanliness classes. For example, an ISO 14644-1 Class 1 cleanroom requires a particle count of no more than 10,000 PCM per cubic meter.

• US Federal Standard 209E: This is a US federal standard that has been superseded by ISO 14644. However, it is still used by some industries to measure the cleanliness of cleanrooms.

• GMP Standards: Good Manufacturing Practice (GMP) standards are commonly used in pharmaceutical manufacturing to specify cleanliness requirements. These standards will vary depending on the type of product and application.

• Food Industry Standards: The food processing sector may use its own standards to ensure product hygiene and safety, which includes controlling levels of microorganisms and other contaminants.

Testing Programs

• Air cleanliness testing: assesses the cleanliness level of the cleanroom by taking air samples from the cleanroom and counting and sizing airborne particles using specialized particle counters.

• Microbiology testing: This includes sampling the air, surfaces, and personnel in the clean room, and then testing the types and number of bacteria, molds, and other microorganisms present in it through cultivation, microscope observation, and other methods.

• Temperature and humidity detection: through the temperature and humidity meter and other instruments, the temperature and humidity in the clean room for real-time monitoring and recording to ensure that it meets the production requirements.

• Differential Pressure Detection: Measure the pressure difference between different areas in the clean room to understand the direction and speed of air flow.

• Surface Cleanliness Detection: Evaluates the cleanliness of various surfaces (e.g. walls, floors, equipment housings, etc.) within the clean room.

• Vibration and noise detection: assess the clean shed equipment, piping and other vibration and noise on the clean environment and product quality.

• Lighting test: Evaluate whether the illumination, uniformity, color temperature and other indicators of the lighting facilities in the clean room meet the requirements.
