• Frame Material

  The frame of the clean shed is usually made of industrial aluminum profiles or stainless steel squares, and sometimes iron squares with multi-layer pickled electrostatic spraying materials are also used. These materials are not only strong and durable, but also has good corrosion and rust resistance, can ensure the stability of the structure at the same time also has a certain aesthetic.

• Wall materials

  Clean shed wall materials are mostly anti-static curtains or acrylic panels, these materials are highly transparent, clear grid, good flexibility, not easy to deformation or aging, can effectively prevent the generation of static electricity, to maintain the cleanliness of the interior. In addition, some high-end clean shed will also use imported anti-static plexiglass panels to adapt to higher standards of cleanliness requirements.

• Top Cover Material

  The top cover plate of the clean room is generally made of stainless steel or other weather-resistant plates, such as cold-rolled steel electrostatic spraying, which can ensure sufficient strength and provide good sealing performance to avoid the intrusion of dust and other pollutants.

• FFU and Filtration System

  The core part of the clean room is the fan filtration unit (FFU), which filters out airborne particles through a highly efficient filtration system to achieve the required cleanliness level.FFUs are usually equipped with primary filters and high-efficiency filters (HEPA), and some are even fitted with ultra-high-efficiency filters (ULPA) to further improve filtration effects.

• Other Components

  The clean room also includes air intake purification equipment, lighting systems and electrical installations. These components need to be designed and configured in such a way that they do not affect the overall performance of the clean room, but are also easy to operate and maintain.

Fields of application

• Electronic factory

  In electronics factories, clean booths are commonly used in assembly line work areas, inspection benches, special equipment work areas, etc. These areas are often required to release dust particles or handle special gases. The design of the clean shed allows for localized small area construction, and the core process is concentrated in the clean area, which helps to improve the product qualification rate, especially in the optoelectronic industry and other areas with very high requirements for cleanliness.

• Food Factory

  Class 100 clean booths are recommended for food production processes, especially in packaging. This helps to ensure food safety and comply with national GMP food QS standards. As people's awareness of food safety increases, the application of clean booths in the food industry is becoming more and more popular.

• Laboratory

  Laboratory research units are usually located in ordinary office environments, and some of the experiments require specific conditions of temperature, humidity, light and cleanliness. The use of clean rooms creates a clean environment in the experimental workspace that meets these requirements, thereby increasing the success rate of research projects.

Advantages of clean rooms

• Structural Design

  The clean room is designed as an assembled structure, making it easy to install and dramatically shortening the construction period. It can be used not only individually, but also in combination for easy secondary disassembly, providing a high degree of flexibility.

• Mobility

  The bottom of the cleanroom shed is equipped with mobile universal wheels, which makes positioning and moving very flexible and convenient, suitable for constructing local or regional clean space.

• Modular structure

  The modular structure of the top of the clean room makes it possible to adjust the number and size of FFUs, and to use ultra-high efficiency filters to improve the internal cleanliness. This design is not only easy to upgrade the cleanliness level, but also has strong expandability and high reusability value.

• Comparison with other clean equipment

  Compared to ultra-clean benches, clean booths have more internal space. Compared to conventional cleanrooms, the Clean Shed is less costly, quicker to construct, and easier to operate.

Floor requirements

The floor of the clean room must be flat, free of gaps, and wear and corrosion resistant to prevent the accumulation of any substances that may affect cleanliness. Epoxy self-leveling flooring with a thickness of more than 1mm is recommended and its service life usually exceeds 6 years. When laying flooring materials, a moisture barrier should be provided underneath and ensure that bin lines do not pass through clean areas to prevent cross-contamination.

Wall requirements

Walls should be smooth, level, dust free and resistant to corrosion. Colors should be coordinated to help identify contaminants. Interior wall coatings shall contain anti-mold, anti-static and disinfectant materials to maintain a clean and germ-resistant wall surface. The junction of the wall and floor should be painted with an arc of at least 50mm radius to minimize dust accumulation and facilitate cleaning and maintenance.

Installation Precautions

• Installation location: choose a dry, ventilated, well-lit environment, avoid direct sunlight, and meet special requirements, such as anti-static and anti-corrosion.

• Foundation construction: ensure that the foundation construction meets the design requirements, the foundation should be level, solid and horizontal, and only after acceptance can the installation continue.

• Frame installation: use the frame made of steel section, ensure verticality and levelness during installation, and carry out anti-corrosion and anti-rust treatment after completion.

• Roof and wall plate installation: use purification board or other materials that meet the clean requirements to ensure the flatness of the roof and wall plate, and tight seams to avoid loopholes.

• Air purification system installation: the interior should be equipped with an air purification system, including high-efficiency filters, air showers, ultraviolet disinfection lamps, etc., to ensure that the components are connected tightly to avoid air leakage.

• Lighting system installation: the interior should be equipped with waterproof and dustproof lighting system to ensure the uniformity of lighting.

• Electrical system installation: the electrical system should comply with national standards and industry requirements to ensure stable and safe power supply.

• Grounding treatment: the grounding treatment should meet the design requirements to ensure the safe operation of the equipment.

• Acceptance and debugging: carry out acceptance after the installation is completed to ensure the normal operation of the systems and achieve the expected clean effect.

• Measurement of Air Supply and Exhaust Volume

  For a turbulent flow cleanroom, the supply and exhaust air volumes are measured, while for a unidirectional flow cleanroom, the air velocity is measured. This is because unidirectional flow cleanrooms are designed to allow air to flow in one direction, effectively minimizing the possibility of cross contamination.

• Airflow Control Inspection

  The inspection also ensures that the airflow between zones is moving in the correct direction, i.e. from the clean zone to the less clean zone. This includes checking that the pressure differential between zones is correct and that the direction of airflow movement at doorways or openings in walls, floors, etc. is compliant.

• Filter Leak Detection Inspection

  Inspection of HEPA filters and their frames is essential to ensure that suspended contaminants do not enter the room through damaged filters, gaps between filters and their frames, or other areas.
