A pass box is an auxiliary equipment in a clean room, mainly used for transferring small items. So what is the difference between a regular pass box and an air shower transfer window?
I’m here to tell you today.
Let’s first talk about the similarities between the air shower transfer window and the pass box:
1. pass box and air shower transfer windows are mainly used for the transfer of small items between clean areas and clean areas, as well as between clean areas and non clean areas, to reduce the number of door openings in clean rooms and minimize cross contamination between clean areas.
2. Transmission windows and air shower transmission windows can be divided into electronic interlocking transmission windows and mechanical interlocking transmission windows according to their interlocking methods. The transmission windows and doors are both double door interlocked, meaning that only one door can be opened at a time, and once one door is opened, the other door cannot be opened
3. Transfer windows and air shower transfer windows can be divided into stainless steel transfer windows, outer steel plate inner stainless steel transfer windows, etc. according to the material of the box. The commonly used plates for making transfer windows include cold-rolled steel plates (A3 plates) and stainless steel plates (SUS201, SUS304, SUS316, etc.). The thickness is generally 0.8-1.5mm.
Let’s talk about the two differences between air shower transfer windows and ordinary transfer windows:
The difference between an air shower transfer window and a regular pass box is that an air shower transfer window adds an efficient filtering and air supply system, as well as 360 degree no dead angle blowing on the basis of a regular transfer window. Ordinary transfer windows are suitable for simple item transfer, while air shower transfer windows are more suitable for use in Class 100 or Class 10 high clean spaces.
