In industries with extremely high requirements for production environments, such as precision manufacturing, biomedicine, and electronic semiconductors, cleanrooms are core infrastructure for ensuring product quality and mitigating contamination risks. ISO 7 cleanrooms, as one of the most widely used cleanroom grades, are defined according to the international standard ISO 14644-1 and serve as a "cleanliness benchmark" for most mid-to-high-end industries. Their core value lies in scientifically controlling the environment to strictly limit airborne particles, microorganisms, and other contaminants within specified limits, providing a stable and controllable working space for various high-precision, high-sterility production activities.

Biosafety cabinets (BSCs) are essential negative pressure purification and safety equipment in biological laboratories. Their core function is to protect operators, experimental samples, and the laboratory environment, avoiding contamination and exposure risks caused by infectious aerosols and splashes generated during operation.

For sterile medical devices implanted or inserted into blood vessels that require subsequent processing (such as filling and sealing) within a localized Class 100 cleanroom at a Class 10,000 cleanroom level, or for individually packaged accessories, the processing of (unwashed) components, final cleaning, assembly, initial packaging, and sealing should be carried out in areas with a cleanliness level of at least Class 10,000.

For sterile medical devices implanted into human tissue or directly or indirectly connected to blood, bone marrow cavities, or non-natural cavities, or for individually packaged accessories, the processing of (unwashed) components, final cleaning, assembly, initial packaging, and sealing should be carried out in areas with a cleanliness level of at least Class 100,000.

For primary packaging materials that come into direct contact with the surface of sterile medical devices and are used without cleaning, the cleanliness level of the production environment should be the same as that of the product's production environment. This ensures that the quality of the primary packaging materials meets the requirements of the sterile medical devices being packaged. If the primary packaging materials do not come into direct contact with the surface of sterile medical devices, production should be carried out in a cleanroom (area) with a cleanliness level of at least 300,000.

For sterile medical devices (including medical materials) that require aseptic processing techniques, production should be carried out in a localized Class 100 cleanroom (area) with a cleanliness level below Class 10,000.

Airborne E. coli and Salmonella can contaminate food, and a single speck of dust can destroy a computer chip. Therefore, cleanrooms are as common as household air purifiers. Enterprises utilizing Class 100,000 cleanroom projects can effectively reduce airborne dust, bacteria, and viruses, and achieve constant temperature, pressure, and noise levels, providing a superior production environment. The application of the Class 100,000 cleanroom standard is widespread. During production, the cleanroom must be dynamically monitored in real-time to ensure it meets the Class 100,000 cleanroom standard.

A food aseptic workshop is a special clean space that ensures safe food production by controlling microorganisms and particulate matter in the environment to extremely low levels through air purification, airtight isolation, temperature, humidity and pressure differential control, and strict management of personnel, materials and equipment. It is the core production carrier for high-risk foods (such as dairy products, ready-to-eat foods and aseptically packaged beverages).

As a professional manufacturer of modular cleanrooms, combining biopharmaceutical GMP compliance standards with practical experience, the aseptic laboratory air shower passage must meet the following core GMP compliance validation requirements, fully adhering to the IQ/OQ/PQ full validation process, thus building a solid first line of defense for aseptic protection.
