Frame Material

The frame of the clean shed is usually made of industrial aluminum profiles, stainless steel square or plastic spraying iron square, etc. These materials have good stability, corrosion resistance and non-dust-producing properties, which ensures that the clean shed is sturdy and beautiful.

Anti-static curtain material

Anti-static drape is an important part of the clean room, usually made of transparent PVC with a grid formed by black conductive ink. This design not only provides good anti-static effect, but also has high transparency and clear grid, and also has good flexibility and durability, and is not easy to be deformed and aging.

Top material

The roof is usually made of 1.2mm thick cold rolled steel plate for electrostatic spraying treatment. This material is not only strong and durable, but also effective in preventing the accumulation of dust and other pollutants and maintaining the cleanliness of the interior.

Fan Filter Unit (FFU)

Fan filter unit (FFU) is the heart of the clean room, it is responsible for providing continuous clean air, FFU usually adopts high-efficiency centrifugal fan, has a long life, low noise, free of maintenance and other characteristics, and can be adjusted to achieve the best air speed and air volume to adapt to different clean requirements.

Structural design

The structural design of the Clean Shed is an assembled unit that is easy to install and easy to disassemble, dramatically shortening lead times. This design allows the clean room to be used not only in factory environments, but also in temporary or mobile workplaces for quick setup.

Mobility and Suitability

Mobility is another key feature of the Clean Shelter. The chassis, equipped with universal wheels, makes it easy to move between sites or work areas, making it ideal for situations where frequent changes in the workplace are required. In addition, the Clean Shed is suitable for the construction of small clean areas, especially for processes with special cleanliness requirements.

Modularity and Expandability

The modular design of the cleanroom allows for flexibility in terms of increasing cleanliness levels and expanding space. Users can add or reduce modules according to actual needs to adapt to different scales of cleanliness requirements. This design not only saves costs, but also increases the value of reuse.

Comparison with conventional clean rooms

Compared to traditional clean rooms, the Clean Shed shows significant advantages in terms of cost, construction speed, and the requirement for floor height. It is cheaper, faster to construct, and is not limited by floor height, enabling rapid deployment in a wide range of environments.

Application Areas

Clean rooms are widely used in the electronics, semiconductor, precision machinery, pharmaceutical and food industries to ensure that products are protected from outside contamination during these critical production processes, thereby improving product quality and productivity. In laboratories and scientific research, clean rooms also provide researchers with a dust-free, germ-free experimental environment, helping them to conduct accurate experimental research and data analysis.

Preparation before installation

Before installing a clean shed, the installation site should first be inspected to ensure that the environment is dry, ventilated and well lit, avoiding direct sunlight. At the same time, the installation site should be thoroughly cleaned and wiped, especially the inside of the air-conditioning system, in order to meet the cleanliness requirements. In addition, all necessary materials and tools should be prepared, such as purification boards, steel profiles, and laser levels.

Foundation construction

Foundation construction is an important prerequisite for the installation of the clean room, you need to ensure that the foundation is level, solid and horizontal. Acceptance should be carried out after construction, and it can only be continued after passing. Frame installation should be composed of steel profiles and other materials, the installation needs to ensure the verticality and horizontality of the frame, and complete the anti-corrosion and anti-rust treatment.

Ceiling and wall panel installation

During the installation of ceiling board, it is forbidden to use hard tools to directly touch the surface of steel plate to prevent scratching. When moving the metal color steel plate, it should be held gently and put down lightly to avoid damage caused by lifting it horizontally. After installation, it should be sealed in time to prevent scratching or damaging the filler. At the same time, the dust generating operation should be strictly controlled to ensure the cleanliness of personnel entering and leaving.

Installation of FFU and filter

Transportation and storage of FFU high-efficiency filters should be carried out according to the instructions of the manufacturing plant to avoid violent vibration and collision. Appearance inspection should be carried out before installation to confirm that there is no damage and then leakage check should be carried out to ensure that the quality is qualified before installation. The installation should be reasonably deployed according to the resistance size of the filters to ensure that the difference in resistance between the filters is less than 5% in unidirectional flow.

Electrical system installation

The installation of the electrical system of the clean room should meet the national standards and industry requirements to ensure that the power supply is stable and safe, and to ensure the normal operation of electrical equipment. The grounding treatment should also meet the design requirements to ensure the safe operation of the equipment inside the clean room.

System debugging and testing

After the installation of clean room is completed, system debugging and testing should be carried out, including air conditioning system operation, cleanliness testing and equipment function testing. Ensure the normal operation of the system to achieve the desired clean effect.

Air Supply and Exhaust Volume

For a turbulent flow cleanroom, the air supply and exhaust volume should be measured to ensure that the air circulates and maintains cleanliness. For unidirectional flow cleanrooms, air velocity should be measured to ensure that the air flows unidirectionally along a predetermined path to avoid cross-contamination.

Airflow Control

Inspection must ensure that the airflow between zones is moving in the correct direction, from the clean zone to the area of poor cleanliness. This includes checking that the differential pressure between zones is correct and that the airflow direction is correct at doorways or openings such as walls and floors.

Filter Leakage Inspection

High efficiency filters and their frames are inspected to ensure that suspended contaminants do not penetrate through damaged filters, gaps between filters and frames, or other parts of the room.

Isolation Leak Test

This test is designed to prove that suspended contaminants do not penetrate through construction materials into the cleanroom, ensuring the purity of the cleanroom interior.

Indoor Airflow Control

The type of airflow control test is based on the airflow pattern of the cleanroom, whether turbulent or unidirectional, and must meet the design requirements. In the case of a turbulent flow cleanroom, it is verified that there are no areas of insufficient airflow; in the case of a unidirectional flow cleanroom, it is verified that the air velocity and direction throughout the room meets the design requirements.

Suspended Particle Concentration and Microbial Concentration

These tests are used to ensure that the particle and microbial concentrations in the cleanroom meet the technical conditions, especially important for processes that are sensitive to contamination.

Other Tests

In addition to the above tests for contamination control, tests for temperature, relative humidity, indoor heating and cooling capacity, noise levels, light levels, and vibration levels are sometimes required to comprehensively assess the overall performance of the clean room.
