• Frame Material

  The frame of a clean room is usually made of industrial aluminum profiles, stainless steel squares or iron squares sprayed with plastic, which are not only strong and beautiful, but more importantly, they do not rust and do not produce dust, which makes them ideal for use in clean environments. The lightweight and high-strength properties of aluminum profiles make it an ideal choice for building clean shelters. In addition, the plastic spray treatment effectively prevents rusting of the metal material and extends the service life of the cleanroom.

• Anti-static drape material

  Anti-static drapes are an important part of the cleanroom and are made of special anti-static materials, such as anti-static acrylic panels or toughened glass, designed to reduce the build-up of static electricity and avoid damage to sensitive electronics. These materials have good transparency and grid clarity, as well as flexibility and durability, allowing them to adapt to various environmental changes while maintaining cleanliness.

• FFU Materials

  The fan filter unit FFU is the heart of the clean room, it is responsible for providing a continuous flow of clean air.FFU usually adopts a centrifugal fan, which is characterized by long life, low noise, maintenance-free and low vibration, etc. Its internal high-efficiency filter is capable of capturing the cleanliness of products. The high efficiency filters inside the FFU can capture tiny particles and ensure that the air delivered reaches the predefined cleanliness level.The design of the FFU also allows stepless variable speed to regulate the air speed and air quality inside the clean room.

• Cleanroom Lighting Materials

  The lighting equipment inside the clean room uses special purification lamps, which do not produce dust and avoid potential contamination of the clean environment due to dust accumulation. The purification lamps have a stable source of light and are uniform, providing sufficient illumination while maintaining cleanliness inside the clean room.

Structural Features

The structural design of the Clean Shed is of the assembly type, which is easy to install and can quickly shorten the delivery cycle. It is very mobile and suitable for building clean areas in small areas. The modular structural design makes it easy to upgrade the cleanliness level of the clean room, and it is highly expandable and easy to reuse.

Application Advantages

Compared to traditional clean rooms, clean booths have the advantages of low cost, fast construction, and are not limited by floor height. Compared with civil engineering or assembly type Class 100 clean rooms, the clean room has less investment, faster results and lower operating costs. In addition, the effective space inside the clean room is larger than that of an ultra-clean bench, providing users with a larger working area.

Applications

• Electronics manufacturing: In SMT placement, chip packaging, testing, etc., the clean room can provide a dust-free environment to protect sensitive components from contamination.

• Pharmaceutical industry: in the aseptic production, preparation filling, etc., the clean shed to ensure the purity of the drug production environment, to protect the quality of drugs.

• Food industry: In baking, packaging, etc., the clean room helps to maintain the freshness and hygiene standard of food.

• Laboratories and research institutes: In fine chemical synthesis, cell culture and other experiments, clean rooms provide the necessary clean environment.

• Prepare installation tools: Before installation, make sure all the necessary tools and materials are complete, including screwdrivers, leveling tape, and so on.

• Installation frame: Two people climb up to the ceiling, lay the metal foot keel and hand-supported lifting trusses, while the other two people put the FFU on the table and prepare the high-efficiency filter.

• Fixed aluminum ladder: two people are needed to assist in fixing the aluminum ladder and lifting the fan unit to the ceiling to ensure horizontal placement.

• Tilt mounting the FFU: Tilt the FFU to the ceiling and catch it by the person above.

• Handling the FFU: In the clean room, two people holding the HEPA filter hand it over to the staff for installation.

• Installing the filter: Install the filter diagonally towards the keel, taking care to protect the HEPA filter as it is fragile and critical.

• Install the HEPA filter horizontally: Make sure the filter is effectively combined with the keel.

• Installation of Fans: Put down the FFU, install the fans close to the high-efficiency filter, take care not to damage the filter, and check whether the FFU is pressed tightly.

• Inspection and debugging: Check after the installation is completed to ensure that all components operate normally and achieve the expected clean effect.

Dust Particle Count Test

• Purpose of Testing

  Particle count testing is a key part of ensuring that the performance of a clean room is up to standard. Through the test, we can determine whether the clean room has reached the expected cleanliness level, so as to ensure the aseptic environment and product quality in the production process.

• Testing Standards

  According to ISO 14644-1, the suspended particle count inside the clean room should be controlled within a certain range from static to dynamic. The maximum permissible number of particles is 3500 particles/m³ in static mode and 7500 particles/m³ in dynamic mode.1

• Detection method

  Detection is carried out using a laser dust particle counter, which is capable of monitoring and counting the number of particles in different size ranges in real time. When testing, it is necessary to set up a reasonable sampling point in the clean room, usually in the production workshop, the sampling point can be set in the column or wall at a height of about 2.5 meters; if there are sanding machines and other equipment, the sampling point can be set in the equipment above the 0.5-2 meters.

Wind Speed Test

• Purpose of testing

  The purpose of wind speed testing is to ensure that the air flow in the clean room meets the requirements, and to determine whether the air purification equipment is operating normally and whether its configuration is reasonable.

• Testing standard

  The wind speed inside the clean room should be controlled between 0.2-0.5m/s, which is conducive to maintaining the cleanliness inside the clean room.

• Test Method

  Use professional anemometer to measure, make sure the sensor of anemometer is correctly placed, and record the readings of each position, so as to judge whether the wind speed is uniform and within the standard range.

Ventilation test

• Detection purpose

  The number of air changes reflects the freshness of the air inside the clean room and the load on the purification equipment. Appropriate number of air changes is essential to maintain a stable environment inside the clean room.

• Testing standard

  In general, the number of air changes should be controlled at 3-5 times per hour, which helps to continuously renew the air inside the clean room and reduce the accumulation of pollutants.

• Testing Methods

  By monitoring the operation of the equipment and calculating the number of air changes, it is possible to assess whether the air circulation in the clean room is reasonable.
