The Pass box is a kind of auxiliary equipment for the clean room. It can be said to be a clean mirror. It consists of the left box body, the right box body (the interlock device is installed in this box), the upper box body, the lower box body, the inner wall and the transfer window. The door structure is composed. According to the material of the box, it can be divided into stainless steel transfer window, outer steel plate and inner stainless steel transfer window. It is mainly used for the transfer of small items between the clean area and the clean area, between the clean area and the non-clean area, to reduce the number of door openings in the clean room and reduce the pollution of the clean room to a certain degree.

Pass box


Its general installation process is to choose a convenient location on the wall, and then open a hole. The hole is generally about 10MM larger than the outer diameter of the transfer window. Put the transfer window into the wall, generally install it in the middle of the wall, keep balance and fix it, and use rounded corners. Or other decorative strips can be used to decorate the gap between the transfer window and the wall, which can be sealed and modified with glue.
The transmission window can be divided into different interlocking modes: electronic interlock transmission window and mechanical interlock transmission window.
A. The mechanical interlocking system can effectively reduce cross-contamination when transferring items. Mechanical interlocking is achieved through the process of mechanical interlocking system. For example, two switches cannot be closed at the same time through a mechanical lever.
B. Electronic interlocking is achieved by electric interlocking device instead of mechanical interlocking system technology. For example, two switches cannot be closed at the same time through the electric lock lever.
C, KLCFILTER purification interlock transfer window through the improvement of the internal structure of the interlock system, reliable and stable performance.

Transfer window


The pass box is managed according to the cleanliness level of the higher-level clean area connected to it. For example, the transfer window connected between the coding room and the filling room should be managed according to the requirements of the filling room. After get off work, the operator in the clean area is responsible for cleaning the internal surfaces of the transfer window, and turning on the UV lamp for 30 minutes.
1. Materials entering and exiting the clean area must be strictly separated from the human flow channel, and the material entry and exit of the production workshop must be dedicated.
2. When the material enters, the raw and auxiliary materials are unpacked by the person in charge of the preparation work process or the exterior is cleaned, and then sent to the workshop raw and auxiliary material temporary storage room through the transfer window; the inner packaging materials are removed from the outer temporary storage room after the outer packaging, It is sent to the inner compartment through the delivery window. The workshop integrator and the person in charge of the preparation and inner packaging processes handle the material handover.
3. When passing through the pass-through window, the “one open and one closed” requirement for the inner and outer doors of the pass-through window must be strictly implemented, and the two doors cannot be opened at the same time. Open the outer door to put the material in and close the door first, then open the inner door to take the material out, close the door, and so on.
4. When the materials in the clean area are sent out, the materials should be transported to the relevant material intermediate station first, and the materials should be moved out of the clean area according to the reverse procedure when the materials enter.
5. All semi-finished products transported from the clean area must be sent from the transfer window to the external temporary storage room, and then transferred to the external packaging room through the logistics channel.
6. Materials and wastes that are highly likely to cause pollution should be transported to the non-clean area from its dedicated transfer window.
7. After the material entering and exiting, clean up the cleaning room or the site of the intermediate station and the hygiene of the transfer window in time, close the internal and external passage doors of the transfer window, and do a good job of cleaning.
