• Frame Material

  The frame of the clean shed is usually made of industrial aluminum profiles or stainless steel squares, which have good corrosion and rust resistance, and at the same time ensure a solid and beautiful structure. Aluminum profiles are widely used in clean rooms because of their light weight and high strength. Stainless steel square pass, on the other hand, has an indispensable role in some special environments due to its corrosion and high temperature resistance.

• Wall material

  Clean shed wall materials are diverse, commonly used anti-static curtains, acrylic panels and tempered glass. Anti-static curtains can effectively prevent the accumulation of static electricity, suitable for static-sensitive areas. Acrylic sheet is used for its good light transmission, color and is used in clean room need good lighting. Tempered glass is often used in situations where internal observation is required due to its transparent nature.

• FFU (Fan Filter Unit)

  FFU (Fan Filter Unit) is an important part of the clean room, which is responsible for providing a continuous and stable flow of clean air.FFU usually adopts centrifugal fans, which have the advantages of long service life, low noise, and maintenance-free, etc. The quality and working life of the fans directly affect the quality of the clean room. The quality and working life of the fan directly affects the efficiency of the clean room.

• Internal Fittings

  The interior of the clean room will be equipped with special purification lamps, these lamps do not produce dust, to ensure the cleanliness of the internal space. In addition, there will be a control box to facilitate the operation and management of the clean room, to ensure the safety of the operator.

• Structural Features

  The design of clean shed usually adopts assembled structure, which facilitates quick installation and shortens the delivery cycle. The bottom is equipped with universal wheels for easy movement and adjustment to adapt to changing production needs. In addition, the modular design makes the clean room easy to expand and upgrade, as well as highly economical. Users can configure areas with different cleanliness levels according to actual needs to achieve a localized high cleanliness environment.

• Cost Effectiveness

  Compared to traditional clean rooms, clean rooms are less expensive to build, faster to construct, and do not require high floor heights, making it possible to achieve efficient air purification within limited space and budget. This structural flexibility makes the Clean Shed an economical and practical choice.

• Application Scenarios

  The clean room is suitable for production processes that require localized high cleanliness, such as SMT placement, chip packaging, laboratory testing, etc. It can be used to significantly improve product quality. Its use can significantly improve product quality and reduce the rate of defects caused by dust contamination, especially suitable for enterprises with strict requirements on cleanliness.

• Technical details

  The core of the clean room lies in its high efficiency filtration system. Through the FFU fan filtration unit, combined with primary and high efficiency filters, it ensures that the air is sent into the clean area at a constant wind speed to maintain the cleanliness of the work area. In addition, the structural design of the Clean Shed includes anti-static drapes, purification lamps, etc., all of which together constitute its powerful purification capability.

Installation Steps for Clean Sheds

• Construction preparation

  Before the construction, you need to understand the design drawings and construction requirements of the clean shed in detail, prepare the necessary materials and equipment, and the construction staff for the appropriate technical training.

• Foundation project

  Ensure that the ground in the construction area is level, free of dust and other impurities, and carry out foundation treatment and construction according to the design requirements.

• Frame Installation

  The frame of the clean room is usually made of industrial aluminum profile or stainless steel, which needs to ensure its solidity and stability.

• Wall and ceiling installation

  Choose suitable panels, such as stainless steel panels or anti-static materials, for wall and ceiling installation, and ensure good sealing performance.

• Door installation

  According to the design requirements, choose suitable door type (e.g. PVC drape door or automatic door), and ensure good airtight performance.

• Installation of air purification system

  Including the installation of FFU (Fan Filter Unit), ensure the reasonableness of air duct design and air volume to meet the cleanliness requirements.

• Electrical System Installation

  Installation of the electrical system, including but not limited to lighting, power supply and control system to ensure safety and compliance with electrical codes.

• Commissioning and Testing

  Upon completion of installation, carry out comprehensive system debugging and testing, including cleanliness testing, equipment function testing, etc., to ensure normal operation of the system.

• Acceptance

  Acceptance of the project is carried out according to relevant standards and specifications to ensure that the clean room meets the intended cleanliness requirements.

Precautions

• Material Selection: Choose materials with good airtightness and small deformation, especially the wall and ceiling materials need to meet the requirements of flat, smooth and dust-free.

• Construction quality: the construction process should be strictly quality control to ensure that each link meets the design requirements.

• Environmental control: The construction environment should be dry, ventilated, and well lit, and necessary measures should be taken to prevent the generation of dust and pollutants.

• Safety measures: Construction personnel should wear appropriate protective equipment and take safety measures against fire and electricity.

• Protection of finished products: The completed part should be properly protected to prevent damage during construction.

Cleanliness Standards

The cleanliness of a cleanroom is usually measured in terms of Particles per Cubic Meter (PCM) or Particles per Cubic Foot (PCF).

• ISO 14644: This is an international standard that defines cleanliness levels for cleanrooms. the ISO 14644-1 standard specifies particle count limits for various cleanliness levels.

• 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 Processes

• Air cleanliness testing: By taking air samples from the clean room, airborne particles are counted and sized using specialized particle counters.

• Microbiology Detection: This includes sampling the air, surfaces, and personnel in the clean room, and then detecting the types and numbers of bacteria, molds, and other microorganisms present in them through cultivation, microscopic observation, and other methods.

• Temperature and humidity detection: Use temperature and humidity meter and other instruments to monitor and record the temperature and humidity in the clean room in real time.

• Differential Pressure Detection: Measure the pressure difference between different areas in the clean room by using instruments such as differential pressure meters 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: through the clean shed equipment, piping, etc. for vibration and noise detection, to assess its impact 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.

Test results

The test results will be judged according to parameters such as the concentration of particles or the number of microorganisms specified in the standard to determine whether the clean room complies with the predetermined cleanliness level. If the test results show that the cleanliness is not up to standard, appropriate measures need to be taken to rectify the situation until the desired cleanliness level is achieved or restored.
