The transfer window is a commonly used equipment in clean rooms, and its role is mainly to prevent air pollution and cross pollution in clean rooms.

Clean room is a specific working environment, which meets the requirements of the production process by strictly controlling the indoor temperature, humidity, dust particle number and other parameters. In the clean room, the cleanliness of the air is crucial to the quality of the product and the stability of the production. However, in the actual production process, due to the entry and exit of personnel, the entry and exit of items and the operation of indoor equipment and other factors, the air cleanliness of the clean room is often polluted to different degrees. As an important equipment, the transfer window can effectively prevent the entry of external polluted air when personnel and items enter and exit the clean room, so as to ensure the air cleanliness of the clean room.

In a clean room, air cleanliness requirements may vary between different areas or different production lines. If the air flow between different areas or production lines is not sufficient, it may lead to cross-contamination between different areas or production lines. As a device for transferring goods, the transfer window can achieve air isolation between different areas or production lines when personnel enter and exit and goods are transferred.
