Benefits and purchase suggestions of stainless steel pass box

A stainless steel pass box is a highly efficient purification equipment used to transfer small items between clean areas and non-clean areas to prevent contamination effectively. It is usually used as a transfer device in clean rooms and is economical and practical.

The benefits of stainless steel pass boxes are not only to maintain the air cleanliness level but also to ensure the safety of personnel operations. For some areas where there may be biological hazards (such as virus and bacteria infection risks) or chemical contamination risks, a pass box reduces unnecessary entry and exit of personnel, which reduces the frequency and duration of personnel exposure to these harmful environments, and controls safety hazards from the source, especially in infectious disease research laboratories, highly toxic chemical synthesis workshops and other places, its safety guarantee role is vital.
There are several main points to note when choosing a pass box:
1. The first point is to confirm the custom size and consider whether the finished transfer window can be installed more closely on the partition wall. If the product size is wrong or too large, the installation port size needs to be adjusted, and the workload increases. If it is too small, it needs to be filled. If the filling area is too large, air leakage is prone to occur, which will also affect the cleanliness of the clean room.
2. Generally speaking, the material of the pass box is 304 stainless steel, which is easy to clean and has a long service life. The chemical elements contained in it can maintain the inherent corrosion resistance of stainless steel.
3. In terms of manufacturing process, each manufacturer is different. When we check whether a pass box is qualified or excellent, we mainly look at its sealing performance. The most essential meaning of the pass box is to establish a sealed space to clean the items. If the sealing performance is poor and there is air leakage, it is easy for the clean room to fail to meet the specifications. We can check the process details of the product. The most important point is how the air exposure surface of the pass box is isolated from the clean area. For example, in the treatment on the door body, whether it is integrated or spliced, the probability of air leakage in the spliced ​​type is still higher than that of the integrated type.
4. Most pass boxes have interlocking devices, including mechanical interlocking and electronic interlocking. This device prevents the doors of the clean area and the non-clean area from being opened at the same time, allowing untreated air to pass directly and cause pollution. In the pass box, an additional operating device means an increase in the risk of leakage and maintenance. We need to understand how the manufacturer solves this difficulty, whether there is an inspection port, and whether the maintenance is troublesome and complicated.
