The transfer window is an essential component in cleanroom operations, designed to facilitate the safe and controlled movement of materials between clean and non-clean areas. It functions as a buffer zone that prevents contamination by maintaining air pressure differentials and minimizing cross-contamination. To ensure effective operation, it is crucial for industrial facilities to establish clear usage protocols that safeguard the integrity of the cleanroom environment.
1. All materials entering or leaving the clean area must follow designated pathways, using only the material-specific channels within the production workshop. This helps prevent direct exposure to non-clean zones.
2. When materials are received, raw materials should be unpacked or cleaned by the responsible personnel from the preparation process before being transferred through the transfer window to the workshop's temporary storage room. For externally packaged items, the outer packaging is removed, and the inner packaging is then passed through the transfer window to the internal packaging area. The workshop integrator and the relevant process supervisors handle the handover of materials.
3. When using the transfer window, strict "open and close" procedures must be followed. The inner and outer doors must never be opened simultaneously. After opening the outer door, place the material inside, close the door, then open the inner door to retrieve the item, and repeat the process to maintain the cleanroom’s integrity.
4. When removing materials from the clean area, they should be transported to the appropriate intermediate storage station and then taken out following the reverse procedure used for incoming materials.
5. All semi-finished products must be moved out of the clean area via the transfer window to an external temporary storage room and then transported to the outer packaging area through the logistics channel.
6. Materials and waste that are particularly prone to contamination should be handled through dedicated transfer windows to ensure they do not compromise the cleanroom environment.
7. After each use, the transfer window and its surroundings should be promptly cleaned and disinfected. Both the inner and outer doors must be closed securely to maintain hygiene standards.
Transfer windows serve as critical auxiliary equipment in cleanroom systems, enabling the transfer of small objects between clean and non-clean zones or between different pressure levels of cleanrooms. They function as an air lock, preventing the loss of high-pressure air in the cleanroom while also providing a blowing mechanism during the transfer process to ensure the cleanliness of items entering the clean area. The blowing duration can be adjusted based on actual needs, typically set at 1 minute, to optimize efficiency and energy conservation.
