• Frame Materials

  The frame of a cleanroom shed is usually made of industrial aluminum extrusions or stainless steel square tubing. These materials offer good strength and rigidity, and are ideal for use in clean environments due to their non-rusting, non-dust-producing properties. Aluminum profiles are widely used due to their lightweight, strong, and aesthetically pleasing characteristics, and aluminum does not suffer from rusting problems over time, maintaining the overall integrity of the cleanroom.

• Shell material

  The shell part is generally made of 0.5mm thick mesh anti-static PVC curtains and anti-static plexiglass panels. This design not only provides a good anti-static effect, but also ensures a high degree of transparency so that the internal staff can clearly observe the external situation. In addition, the shell of this material has good toughness and resistance to deformation, which can keep stable and not easy to aging in a long time use, ensuring the long-term use of the clean shed.

• FFU Fan Filtration Unit

  The FFU (Fan Filter Unit) used inside the clean room is a key component, which adopts a low-noise centrifugal fan with long life, low noise, maintenance-free and low vibration characteristics. The high efficiency filter (HEPA) is located at the end of the fan air supply unit, which has the advantages of small initial resistance, large dust capacity, high filtration efficiency, etc., and is easy to replace, ensuring the cleanliness of the air inside the clean room.

• Other features

  The size and purification level of the clean room can be customized according to the specific requirements of the customer to adapt to different usage environments and requirements. In addition, the clean room can be equipped with a purified lighting system to meet specific lighting requirements.

Features of the Clean Shed

• Compact and easy to install: The structural design of the Clean Shed allows it to be easily installed in existing environments, either suspended or floor supported, to quickly build up the required clean area.

• Flexibility: The cleanroom can be used individually or in multiple connections to form ribbon clean areas to suit different space and cleanliness requirements.

• Modular design: The modular design of the cleanroom makes it easy to upgrade the cleanliness level and also facilitates future expansion and reuse.

• Easy maintenance and management: Maintenance of the cleanroom includes regular cleaning, disinfection and replacement of filters, all of which are essential to ensure the continued stable operation of the cleanroom.

Application of clean room

• Electronic manufacturing industry: such as semiconductors, integrated circuits, etc., need very high cleanliness to ensure product quality.

• Pharmaceutical industry: for the production of sterile drugs, biological products, etc., to ensure the safety and effectiveness of drugs.

• Food industry: to produce high-quality food, such as pastries, candies, etc., to prevent food from being contaminated during the production process.

• Scientific research and laboratories: to provide researchers with a dust-free and sterile experimental environment, which helps precise experimental research.

• Preparation before installation

  Before installing an FFU in the top of a clean shed, the clean shed must be thoroughly cleaned and wiped to ensure that the inside of the purified air conditioning system is free of dust. If a high-efficiency filter is to be installed in a technical mezzanine or suspended ceiling, the technical mezzanine or suspended ceiling also needs to be thoroughly cleaned and wiped.

• FFU system testing

  After the clean booth and FFU system have met the cleaning requirements, the FFU system should be tested. After 12 hours or more of continuous operation, clean the clean room again and immediately install the FFU matching high-efficiency filter.

• Transportation and storage of FFU high-efficiency filter

  The transportation and storage of FFU high-efficiency filters should be carried out according to the direction of the manufacturer's instructions. During transportation, it should be held lightly to prevent violent vibration and collision.

• Inspection before installation

  Before installing FFU high-efficiency filter, the package should be unpacked and inspected at the installation site, including whether the filter paper, sealant and frame are damaged; whether the side length, diagonal and thickness dimensions are in accordance with the requirements; whether there are burrs and rust spots on the frame (for metal frames); whether there is a certificate of conformity of the product, and whether the technical performance is in accordance with the design requirements. After that, check whether there is leakage, and those qualified by inspection and leakage detection should be installed immediately.

• Allocation of filter resistance

  The installation should be reasonably allocated according to the resistance of each filter. For unidirectional flow, between the filters of the same air outlet or air supply surface, the difference between the rated resistance of each filter and the average resistance of each filter should be less than 5%.

• The Importance of Clean Rooms

  Clean rooms are widely used in industries such as semiconductor manufacturing, biomedical, and food processing, where the control of contaminants such as particles, microorganisms, and chemicals is particularly critical. As a result, the testing of clean rooms has become a key part of ensuring product quality.

• Testing Standards

  The cleanliness of a clean room is usually measured in terms of particle counts per cubic meter (PCM) or per cubic foot (PCF). This is regulated in detail by the Chinese standard ISO 14644 and the U.S. Federal Standard 209E. For example, the ISO 14644-1 standard specifies particle count limits for different cleanliness levels.

• Testing Programs

  Testing programs for clean rooms include, but are not limited to, temperature, humidity, airborne particles, fresh air volume, differential pressure, and airflow conditions. These tests are essential to ensure the environmental conditions in the clean room.

• Testing Process

  The testing process of a clean room usually includes on-site sampling, laboratory testing, and issuance of a test report. The testing period is usually 7 working days.

• Testing Equipment

  Commonly used testing equipment includes particle counters, differential pressure meters, anemometers, air volume hoods, noise meters, illuminance meters, temperature and humidity meters, etc.
