• Frame Material

  The frame of the clean shed is usually made of industrial aluminum profiles, stainless steel squares or iron squares multi-layer pickled electrostatic spraying materials. These materials have good anti-corrosion and anti-rust properties, as well as both aesthetics and stability. Industrial aluminum profiles are widely used because of their lightweight and high strength characteristics, while its surface is subjected to special treatment processes, such as electrostatic spraying, which further enhances the material's weather resistance and aesthetics.

• Panel Material

  Commonly used materials for the panels of clean booths include cold rolled steel plates (A3 plates) and stainless steel plates (such as SUS201, SUS304, SUS316, etc.), with a thickness generally between 0.8~1.5mm. These plates not only provide good protective properties, but are also easy to clean and maintain, helping to maintain cleanliness inside the cleanroom. Stainless steel sheets are particularly suitable for wet or chemically complex environments due to their excellent corrosion resistance.

• Drape or Glass

  The surrounding area of a clean room can be surrounded by a drape or glass as an enclosure. Anti-static drapes are usually made of PVC with good transparency and a clear grid, which not only prevents the ingress of dust and particles, but also provides a good visual effect. In addition, toughened glass is also a commonly used material, which provides higher strength and light transmittance and is suitable for working environments that require bright light.

• FFU (Fan Filter Unit)

  FFU (Fan Filter Unit) is an important part of the clean room, it is responsible for the new air through the primary filter, and then through the high-efficiency filter, with a wind speed of 0.45m/s ± 20% uniformly into the clean room, to ensure that the air flows vertically and unidirectionally, to maintain the required degree of cleanliness. the quality and performance of the FFU directly affects the clean room's cleanliness and working efficiency. The quality and performance of FFU directly affects the clean effect and working efficiency of the clean room.

• Structural Features

  The structure of a clean room is characterized by its assembled design, which allows for easy installation and short lead times. They are usually equipped with universal wheels for ease of movement and production needs. The modular design makes it easy to upgrade the purification level and has a high reuse value. Compared with the traditional clean room, the clean room has the advantages of low cost, quick construction, and lower requirements for floor height.

• Application Scenarios

  The clean room can be used not only for a single working area, but also for multiple connections to form a strip clean area. Inside the clean room, staff are required to wear special clean clothing, including helmets, masks, gloves and garments to minimize contamination from personnel. Cleanroom cleanliness standards are based on ISO 14644 or other industry-specific GMP standards, etc. Different industries and applications may have different cleanliness requirements.

Installation Points

• Space preparation: Ensure that the installation location is dry, ventilated and well lit, avoiding direct sunlight. At the same time, take into account the special requirements of the clean room, such as anti-static and anti-corrosion.

• Installation location: It is recommended to install the clean shed at the air outlet to extend the service life of the filter. It is not suitable to be installed in dusty, humid or easily corroded by salt and alkali places.

• Cleaning: Before and after installation, use alcohol to clean the soft curtain, FFU, frame, plexiglass and other parts to ensure cleanliness.

• Personnel equipment: Installers should wear clean clothes, protective shoes and helmets when installing in the clean room.

• Sealing measures: If the clean shed is installed in a non-clean room, the doors and windows need to be sealed properly.

• Cleanliness test: After installation, use particle counters and other cleanliness tests to ensure that the requirements are met.

Installation Process

• Environment preparation: Clean and sterilize the installation environment to reduce the dust and bacteria content in the air.

• Assemble the frame: According to the design drawings, assemble the aluminum alloy or stainless steel frame to ensure stability.

• Installation of filters and FFU: Select the right type of filters and install FFU fans, connect the power supply.

• Installation of lighting and ventilation equipment: install lighting system and ventilation equipment according to the requirements to ensure a suitable working environment.

• Debugging: debug the clean room to ensure that all systems operate normally and achieve the expected clean effect.

• Air Volume and Exhaust Volume

  For turbulent flow cleanrooms, testing focuses on the measurement of supply and exhaust air volumes to ensure the effectiveness of the air circulation system. For unidirectional flow cleanrooms, the focus is on measuring air velocity to verify that the air flows evenly along a predetermined path.

• Airflow Control

  Airflow control between zones is tested primarily to demonstrate that airflow is moving from clean areas to areas of poorer cleanliness. This includes checking for the correct differential pressure between zones and the correct direction of airflow movement at doorways or openings such as walls and floors.

• Filter Leak Testing

  Leak testing of HEPA filters and their frames is essential to ensure that the filtration system is effective in retaining suspended contaminants. This includes checking for damaged filters, gaps between filters and frames, and other possible penetration paths.

• Isolation Leak Testing

  Isolation leak testing is performed to demonstrate that suspended contaminants do not penetrate through the building materials into the cleanroom, keeping the indoor environment pure.

• Indoor Airflow Control

  Testing for indoor airflow control is based on the airflow pattern of the cleanroom (turbulent or unidirectional). For a turbulent flow cleanroom, it is necessary to check whether there are any areas where the airflow is insufficiently operated, while for a unidirectional flow cleanroom, it is necessary to verify whether the air velocity and air direction in the whole room are in accordance with the design requirements.

• Suspended Particle Concentration and Microorganism Concentration

  Finally, the concentration of suspended particles and microorganisms in the clean room are measured to prove that they comply with the design technical conditions of the clean room.

• Other Tests

  In addition to the above tests for contamination control, tests for temperature, relative humidity, noise level, illuminance, vibration value, etc. are sometimes required to ensure that the overall performance of the clean room meets the standards.
