• Frame material

The frame of a cleanroom is usually made of 50*50 stainless steel square, a material that offers excellent stability and aesthetics, as well as being non-rusting and non-dust-producing. The use of stainless steel square ensures the structural integrity of the cleanroom, while also providing enough strength and durability to accommodate a variety of work environments.

• Static Drapes Material

The clean shed is often surrounded by an anti-static drape with a 0.5mm mesh, which has a good anti-static effect, high transparency, a clearly visible mesh, good flexibility, not easy to deform, and good durability, not easy to age. This design makes the clean shed can prevent the accumulation of dust at the same time, to maintain a high degree of transparency and aesthetics.

• Acrylic sheet material

Commonly used materials for the top of the clean shed also include fully transparent acrylic panels, which are translucent enough to be comparable to laminated glass, but their hardness is only about half that of tempered glass. The advantage of acrylic panels is that even if they are damaged, they do not produce sharp fragments like tempered glass, thus reducing safety hazards.

• FFU Fan Filter Unit

The key components inside the clean room also include FFU (Fan Filter Unit), which adopts AC EBM355 centrifugal fan with the size of 11751175350mm, and has a high-efficiency two-stage filtration system, capable of filtering 99.99% of the particles of 0.3 um. The design of the FFU allows for the adjustment of the wind speed, and the maximum airflow is 2200m³/min, which ensures the long-time operation. /min, which ensures low noise and high efficiency for long time operation, and at the same time features long life and maintenance free.

• Top & Enclosure

The top of the clean room is usually covered with acrylic panels or mesh soft curtain enclosure, combined with FFU fan filter units, which work together to achieve the required cleanliness level. This design not only ensures cleanliness inside the cleanroom, but also balances structural stability and practicality.

• Structure and characteristics

The clean shed is usually composed of box, fan, primary air filter, damping layer, lamps and so on, and the shell is usually treated with plastic spraying. It can be suspended or ground supported, compact and easy to use. The clean room can not only be used individually, but can also be connected to form a strip clean area.

• Areas of application

Clean booths are widely used in many fields due to their easy installation, short construction period and mobility. Particularly in environments where localized high cleanliness is required, clean booths can significantly reduce costs and provide the required level of cleanliness.

• Installation location requirements

The clean shed should be installed in a dry, ventilated, well-lit environment, avoiding direct sunlight. The installation location also needs to meet the special requirements of the relevant industries, such as anti-static, anti-corrosion and so on. Foundation construction should meet the design requirements to ensure that the foundation is level, solid and horizontal. After the foundation construction, acceptance should be carried out, and the installation of clean shed can be carried out only after passing.

• Foundation construction

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

• Frame installation

Clean shed frame made of steel, installation should ensure that the verticality and level of the frame. 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.

• Testing basis

The testing of clean shed mainly refers to the relevant standards at home and abroad, such as the domestic "Clean Plant Design Code" GB 50073-2001, "Hospital Clean Surgical Department Building Technical Specification" GB 50333-2002, "Biosafety Laboratory Building Technical Specification" GB 50346-2004, "Code for Construction and Acceptance of Clean Rooms" GB 50591-2010, etc., and the international standards ISO 14644 series and ISO 14698 series. These standards cover testing methods and requirements for air cleanliness, air flow, temperature and humidity, differential pressure and many other aspects.

• Types of testing

Clean room testing is usually categorized into three types: empty state testing, static testing and dynamic testing. Empty test refers to the clean shed has been completed and purified air conditioning system is in normal operation, but there is no indoor process equipment and production personnel in the case of the test. Static test is in the normal operation of the air conditioning system and process equipment has been installed, but still no production personnel indoor test. Dynamic testing is testing under normal production conditions.

• Testing items

Clean room testing programs include dust particle counting, microbial detection, differential pressure, and so on. Specific test items will vary depending on the application area of the clean room and specific production requirements. For example, for counting dust particles with a particle size greater than or equal to 0.5 microns, the light scattering particle counting method is preferred, while for counting dust particles with a particle size greater than or equal to 5 microns, the filter film microscope counting method can also be used.

• Detection Frequency

Newly built or remodeled clean rooms should be initially tested to determine their initial cleanliness level. Normal operation of the clean shed should be tested regularly, generally every quarter or half a year. When the clean room appeared abnormal situation or process changes, should be timely testing.
