Air purification equipment transfer window effectively isolates cross contamination
Publish Time: 2025-04-08
In industries such as pharmaceuticals, medical treatment, laboratories, and food processing that require extremely high environmental cleanliness, it is crucial to prevent cross contamination between different areas. As an indispensable part of these environments, the main function of the air purification equipment transfer window is to provide an effective physical barrier to ensure that the transfer of items from one environment to another will not cause the spread of contaminants.
Air purification equipment transfer window is usually made of materials such as stainless steel or aluminum alloy, with good corrosion resistance and sealing performance. It includes two doors (one on each side), which cannot be opened at the same time to avoid cross contamination caused by direct air circulation. In addition, the transfer window is equipped with a high-efficiency air filter (HEPA or ULPA), which can filter out more than 99.97% of 0.3 micron particles in the air, providing a clean transition environment for item transfer.
Interlocking system: The interlocking system equipped with the transfer window ensures that the two doors cannot be opened at the same time. When one door is opened, the other door will automatically lock until the first door is closed. This design effectively blocks the flow of untreated air from one environment to another, thus avoiding the risk of cross-contamination.
High-efficiency air filtration: The built-in high-efficiency air filter not only removes tiny particles and microorganisms from the air, but also maintains a positive pressure state inside the transfer window. The positive pressure environment helps to prevent unfiltered air from outside from entering the transfer window, further ensuring the cleanliness of the items during the transfer process.
Ultraviolet disinfection lamp: Some high-level transfer windows are also equipped with ultraviolet disinfection lamps to sterilize the internal space of the transfer window and the surface of the items. Ultraviolet irradiation can destroy the DNA structure of bacteria and viruses, making them lose their ability to reproduce, thereby achieving the purpose of disinfection.
Air purification equipment transfer window has been widely used in many industries and has proven its effectiveness. For example, in hospitals, transfer windows are used to safely transfer surgical instruments and drugs to reduce the risk of infection; in laboratories, it helps scientists exchange samples under different experimental conditions without worrying about contamination; and in food processing plants, transfer windows ensure that there is no cross-contamination between raw materials and finished products to ensure food safety.
In summary, the air purification equipment transfer window can effectively isolate cross contamination by adopting a variety of technical means such as interlocking system, high-efficiency air filtration and ultraviolet disinfection. This is crucial for places that require a high degree of air quality control. With the advancement of technology, the design of transfer windows will be more intelligent and humane in the future, but its core goal - protecting people from pollution hazards - remains unchanged. Correctly selecting and using the right transfer window plays an important role in maintaining the safety of the working environment, improving product quality and protecting the health of personnel.
