The daily application of the air shower transfer Windows

The air shower transfer window is a purification device that combines the air shower system with the transfer function. It is mainly used for material transfer between clean areas and non-clean areas (or areas of different cleanliness grades). It can not only prevent pollutants from entering the clean area during the transfer process, but also preliminarily purify the surface of the materials. Its daily applications are extensive, involving multiple industries with strict requirements for cleanliness, as follows:
I. Pharmaceutical Industry
Active Pharmaceutical ingredients and preparations production: In the production workshops of antibiotics, vaccines, injections, etc., transfer Windows are used to transfer raw materials (such as pharmaceutical excipients), semi-finished products (such as liquid medicine bottles), packaging materials (such as sterile aluminum caps), etc. The air shower system can remove microorganisms and dust adhering to the surface of materials, avoiding contamination of the production environment in the clean area and meeting the requirements of GMP (Good Manufacturing Practice for Pharmaceutical Products).
Laboratory and quality inspection area: In microbiology laboratories and aseptic testing rooms, transfer Windows are used to transfer samples to be tested, Petri dishes, experimental equipment, etc., to prevent miscellaneous bacteria in the external environment from affecting the test results.
Ii. Electronics Industry
Semiconductors and chip manufacturing: Chip production has extremely high requirements for environmental cleanliness (such as Class 1-100 cleanrooms), and transfer Windows are used to transfer precision components such as silicon wafers, photoresists, and mask plates. The high-speed clean air flow generated by the air shower (usually with a wind speed of ≥20m/s) can remove the tiny particles (such as dust and fibers) on the surface of the material, preventing the particles from adhering to the chip surface and causing short circuits or performance failures.
Electronic component assembly: In the assembly workshop of precision components such as circuit boards and sensors, transfer Windows are used to transfer PCB boards, surface mount components, soldering tools, etc., reducing the impact of dust in the environment on the product qualification rate.
Iii. Food and Health Products Industry
Aseptic food production: In aseptic filling workshops for canned food, juice, dairy products, etc., transfer Windows are used to transfer packaging containers (such as aseptic cartons, glass bottles), production tools (such as filling heads), etc. Air shower can remove bacteria, mold and impurities on the surface of materials, ensuring that food is not contaminated during the filling process and meeting food safety standards (such as HACCP system).
Health product processing: In the production workshops of health products such as protein powder and probiotics, transfer Windows are used to transfer raw materials (such as whey protein) and inner packaging materials (such as aluminum foil bags), preventing external contaminants from entering the clean area and ensuring product purity.
Iv. Medical Device Industry
Sterile medical device production, such as the production workshops of surgical instruments, infusion sets, artificial joints, and other products, involves transferring Windows to transfer instruments to be disinfected, sterile packaging materials, finished products, etc. Air spray can reduce the microbial load on the surface of materials. When combined with subsequent sterilization processes (such as high-temperature steam sterilization and EO sterilization), it ensures that the products meet sterile requirements.
In hospital clean departments: In areas such as operating rooms, ICUs (Intensive Care Units), and burn wards, transfer Windows are used to transfer sterile dressings, surgical instruments, medications, etc., to prevent pressure fluctuations and contamination in the clean area caused by frequent door openings by medical staff.
V. Biological Laboratories and Research Institutions
Biosafety laboratory: In P3 and P4 biosafety laboratories (for studying highly pathogenic pathogens such as the novel coronavirus and Ebola virus), transfer Windows are used to transfer experimental samples, cultures, protective clothing, etc. The air shower system can reduce the risk of pathogen spread with materials while protecting the safety of laboratory personnel and the environment.
Cell and tissue culture: In cell rooms and tissue engineering laboratories, transfer Windows are used to transfer culture flasks, culture media, pipettes, etc., to prevent external microorganisms from contaminating the cell culture environment and ensure the accuracy of experimental results.
Vi. Other industries
In the cosmetics industry, in the aseptic filling workshops of high-end cosmetics (such as essence and eye cream), transfer Windows are used to transfer raw materials, packaging bottles, and components of filling equipment to prevent dust and microorganisms from affecting product quality.
Aerospace industry: In the manufacturing workshops of spacecraft components (such as satellite sensors and aerospace materials), transfer Windows are used to transfer precision parts, and air showers can remove tiny particles on the surface to ensure the stable operation of components in the space environment.
Summary of the core functions of the air shower transfer window
The core lies in achieving the safety of material transfer through "bidirectional isolation + surface purification": on the one hand, the double-door interlock design of the transfer window (the two doors cannot be opened simultaneously) prevents direct air convection between the clean area and the non-clean area; On the other hand, high-speed clean air flows through the air shower nozzles to wash the surface of the material, blowing off contaminants and filtering them out by the return air system, thereby reducing the risk of cross-contamination.
Different industries can select the parameters of the air shower transfer window according to their cleanliness requirements (such as air shower time, cleanliness grade, material, etc.). For example, in the pharmaceutical industry, stainless steel material is commonly used to meet the requirements of corrosion resistance and easy cleaning.
