The air shower transfer window is a purification device that combines the functions of air shower dust removal and item transfer. Its core function is to remove the dust particles adhering to the surface of the items through high-speed clean air flow when transferring items between the clean area and the non-clean area (or areas of different cleanliness grades), prevent cross-contamination, and at the same time avoid the disruption of the air pressure balance in the clean area during the transfer process. Its application fields are highly concentrated in industries with strict requirements for cleanliness, sterility and dust control, and can be specifically classified into the following categories:
I. Biomedical and Medical Device Industry
The control of microorganisms, dust and foreign objects in this industry is directly related to product safety (such as the purity of drugs and the sterility of instruments), and it is one of the core application scenarios of air shower transfer Windows
In the field of pharmaceutical production: It is used for material transfer in raw material drug workshops, preparation workshops (such as injections, oral solid dosage forms), and biopharmaceutical workshops (such as vaccine and antibody production). For instance, before transferring externally purchased auxiliary materials and packaging materials from non-clean areas to clean areas of Class 10,000 or 100,000, surface dust is removed through air showers. Or transfer materials between production rooms of different cleanliness grades (such as weighing rooms and preparation rooms) to prevent contaminants from low-cleanliness areas from being brought in.
In the field of medical device production: For the production process of sterile medical devices (such as syringes, surgical instruments, and implantable medical devices), transfer Windows are used for the cross-regional transfer of molds, semi-finished products, and packaging items, ensuring that products flow in a sterile environment and meeting the requirements of the “Good Manufacturing Practice for Medical Devices” (GMP).
In the fields of laboratories and scientific research: Biosafety laboratories (BSL-2/3), microbiological testing laboratories, and cell culture rooms, it is used to transfer experimental samples, culture media, reagents, experimental equipment, etc., to prevent external miscellaneous bacteria from contaminating the experimental system, and at the same time to avoid the leakage of harmful microorganisms generated during the experiment.
Ii. Food and Health Products Industry
The production process of food and health products must strictly control microbial (such as bacteria, mold) and dust contamination to prevent product deterioration, mold growth or non-compliance with food safety standards. The application of air shower transfer Windows can directly reduce the risk of contamination
Aseptic food production: such as workshops for dairy products (yogurt, aseptic milk), meat products (vacuum-packed cooked food), canned food, and infant formula food, used for transferring raw materials (such as milk powder, meat raw materials), inner packaging materials (such as aseptic packaging bags), and production tools (such as stirring paddles, filling head accessories), to prevent external dust and microorganisms from entering the clean production area.
Health care product/functional food production: Such as probiotic product and health food (capsules, tablets) workshops, transfer Windows are used to transfer probiotic strains, vitamins and other sensitive raw materials to prevent the raw materials from coming into contact with miscellaneous bacteria or dust during transfer, which may affect the activity and purity of the products.
Clean baking/confectionery production: In high-end baking (such as sterile cakes), chocolate and confectionery production, it is used to transfer raw materials that are prone to dust, such as flour and cocoa powder, or to transfer semi-finished products before packaging, reducing dust contamination of the clean area while ensuring that the appearance and taste of the products are not affected by foreign objects.
Iii. Electronics and Semiconductor Industry
Electronic components (especially semiconductor chips and precision electronics) are extremely sensitive to tiny dust particles (such as those smaller than 0.1μm). A single speck of dust may cause a short circuit in the chip or failure of components. The air shower transfer window is a key device for ensuring production cleanliness.
Semiconductor and integrated circuit production: In wafer manufacturing workshops (with cleanliness requirements reaching Class 100 / Class 10) and chip packaging and testing workshops, it is used for transferring wafers, photoresists, masks, packaging materials (such as lead frames), etc. High-speed air shower can remove the tiny dust adhering to the surface of materials, preventing them from causing product scrapping in precision processes such as photolithography and etching.
Precision electronic manufacturing: such as liquid crystal display (LCD/OLED), smartphone camera module, sensor production workshops, transfer Windows are used to transfer glass substrates, lens lenses, chip modules, etc., to prevent dust from adhering and affecting the display effect or sensor sensitivity.
Electronic component assembly: In the assembly workshop of high-end electronic components (such as aerospace electronic components and automotive chips), when materials are transferred, the dust adsorbed by static electricity on the surface is removed through air showers to ensure the reliability of the components.
Iv. Optoelectronics and New Energy Industry
The cleanliness requirements for optoelectronic products (such as photovoltaic modules and optical lenses) and new energy materials (such as positive and negative electrode materials for lithium batteries) are similar to those in the electronics industry, and pollution needs to be controlled through air shower transfer Windows.
Photovoltaic industry: Photovoltaic cell (monocrystalline silicon/polycrystalline silicon) production workshop, used for transferring silicon wafers, silver paste, cutting tools, etc. If dust adheres to the surface of the silicon wafer, it will lead to a decrease in the conversion efficiency of the solar cell. If precious metal raw materials such as silver paste are contaminated, it will increase production costs. Air shower can effectively solve this problem.
Optical industry: Optical lens (such as camera lenses, microscope lenses), laser device production workshops. Transfer Windows are used to transfer lens blanks, coating materials, and optical components to prevent dust from adhering and affecting the light transmittance of the lenses or the beam quality of laser devices.
In the lithium battery industry: In the production workshops of positive and negative electrode materials, separators, and battery cells for lithium-ion batteries (especially power batteries), transfer Windows are used to transfer positive and negative electrode powders that are prone to moisture absorption and dust generation (such as ternary materials and graphite), preventing dust pollution from causing internal short circuits in the battery, and at the same time avoiding external impurities from affecting battery capacity and safety.
V. Other special clean requirements fields
In addition to the above-mentioned mainstream industries, air shower transfer Windows are also applied in scenarios with special requirements for cleanliness:
Aerospace and military industry: In the production and assembly workshops of aircraft engine components and precision components of spacecraft (such as satellite sensors), dust is controlled through air showers during material transfer to ensure the reliability of components in extreme environments.
Hospital clean areas: Sterile operating rooms, icus (Intensive Care Units), and intravenous drug preparation centers (PIVAS) in hospitals are used to transfer surgical instruments, sterile dressings, and prepared intravenous drug solutions, preventing external microorganisms from contamzing the clean areas and reducing the risk of nosocomial infections.
In the nuclear industry: In the production/maintenance workshops of precision components related to nuclear reactors and radioactive detection equipment, transfer Windows (usually combined with radiation protection design) are used to transfer non-radioactive materials, avoiding dust pollution that affects equipment accuracy and reducing the risk of personnel exposure at the same time.
In conclusion, the core value of the air shower transfer window lies in “blocking contamination during cross-clean grade transfer”. Therefore, all industries that have mandatory requirements for “stability of clean environment” are its main application scenarios. Moreover, as the requirements for product quality and safety in various industries continue to rise, its application scope is still gradually expanding.
