Material Selection

• Aluminum: Aluminum is widely used as a frame material for cleanrooms because of its light weight, high strength, and resistance to rust. It provides a strong structural foundation and is easy to disassemble and transport.

• Stainless steel: Stainless steel is commonly used for the frame and some parts of the cleanroom, especially those that require higher strength and corrosion resistance. Stainless steel is effective in preventing rust and adapting to environments with high humidity.

• Anti-static materials: anti-static drapes or mesh curtains are an important part of the clean shed, they can effectively prevent the buildup of static electricity, to avoid damage to sensitive components.

• Acrylic panels: Acrylic panels are often used as wall materials in clean booths for their good light transmission and easy cleaning and maintenance. It provides a good visual effect while maintaining cleanliness inside the clean room.

• High-efficiency filter (HEPA): HEPA filter is a key component to ensure the air quality inside the clean room, it can effectively filter particles in the air and maintain the required cleanliness level.

Structural features

• Frame Structure: The frame is made of aluminum profiles or stainless steel squares, which ensures the overall stability of the clean room.

• Enclosure materials: anti-static drapes or acrylic panels are usually used around the perimeter, while the top is equipped with an FFU fan filtration unit to provide a continuous flow of clean air.

• Mobility: The bottom is fitted with universal wheels, allowing the cleanroom to be easily transferred and redeployed to different locations.

• Modular design: Clean rooms are usually of modular design and can be combined into spaces of different sizes and cleanliness levels as required, providing a high degree of flexibility and expandability.

Main components

• Frame: Industrial aluminum profile is usually used, which has the advantages of no rust and no dust production, and is also easy to disassemble and assemble.

• Anti-static curtain or tempered glass: used to enclose the surrounding edges of the clean room, with good anti-static effect and high transparency.

• Fan Filtration Unit (FFU): Located at the top of the clean room, it is responsible for air supply and air filtration to the required level, and common HEPA filters can effectively intercept small particles.

Application Scenario

Due to the flexibility and mobility of its structure, the clean room is often used in occasions that require temporary or localized high-cleanliness environment, such as production workshops, laboratories, operating rooms, etc. in the electronics, pharmaceutical, food and other industries.

Features and Advantages

The distinctive feature of the clean shed is its ability to be quickly built, easily moved and reused. Compared with the traditional civil structure or assembled clean room, clean shed has the advantages of less investment, quick effect, easy installation and low operation cost.

• Installation Location

  The clean shed should be installed in a dry, ventilated and well-lit environment, avoiding direct sunlight. At the same time, the installation location should meet the special requirements of related industries, such as anti-static, anti-corrosion, etc.

• Foundation construction

  The foundation construction of the clean shed must meet the design requirements to ensure that the foundation is level, solid and horizontal. After the construction is completed, acceptance should be carried out, and the installation of the clean shed can be carried out only after passing.

• Frame installation

  The frame of the clean shed is 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.

• Ceiling and wall plate installation

  The roof and wall plate should be made of purification plate or other materials that meet the clean requirements. When installing, the flatness and tightness of the joints of the ceiling and wall plate should be ensured to avoid any loopholes.

• Air purification system installation

  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, make sure the connection between components is tight to avoid air leakage.

• Lighting system installation

  The interior of the clean room should be equipped with a 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 meet the relevant national standards and industry requirements. When installing, it should ensure the stability and safety of power supply, as well as the normal operation of each electrical equipment.

• Grounding treatment

  The grounding treatment of the clean room should meet the design requirements 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.

Measurement method of air supply and exhaust air volume

• Preparation stage: Before the measurement, it is necessary to ensure that the air supply and exhaust systems in the cleanroom have been running stably for a period of time to ensure the accuracy of the data. In addition, it is also necessary to check the opening of all air outlets and whether the connection of air ducts is correct.

• Measurement stage: Use a professional air volume hood or anemometer for measurement. For air supply outlets, the air volume can be measured directly by using an air volume hood; for exhaust outlets, the same can be done by using an air volume hood or indirectly calculating the air volume by measuring the air velocity of the outlet.

• Data analysis: The collected data needs to be analyzed to determine whether the air supply and air exhaust meet the design requirements. If the measurements show inconsistencies between the supply and exhaust air volumes, the system may need to be adjusted to ensure that the differential pressure and cleanliness in the clean room are in accordance with the standards.

Measurement Methods for Air Velocity

• Choose the right measurement tool: Use a hot-ball anemometer or other type of air velocity measurement equipment to ensure that the accuracy of the equipment meets the cleanroom inspection standards.

• Measurement location: Measure the air velocity at different heights and locations in the cleanroom, especially in the area near the working surface, to ensure that the air velocity is uniform and meets the design requirements.

• Data analysis: Record the measured values of each position and analyze them as a whole to determine whether the wind speed meets the standard of unidirectional flow cleanroom. If the air velocity distribution is uneven or lower than the design value, the air supply system may need to be adjusted.
