Do you know where the easiest place for bacteria to enter the clean room is? It is the connection between the clean area and the non-clean area. Therefore, it needs special equipment to control the pollution during the activities. This cleanroom equipment is the Dynamic Pass Box. In this post, we will share with you this equipment’s requirements and features. 

Dynamic Pass Box

As we just said, the dynamic pass box usually works at the junction of the two machines. Therefore, this equipment function is transferring small items between the clean room area and the non-clean area. In this way, it can reduce the number of doors opening and the pollution to the minimum level. 

And to meet the requirements of the new version of GMP management, the GMP clean transfer window has a special design. As a result, it is more professional and pertinent than the previous ordinary transfer window. 

What are the requirements for the new dynamic pass box?

The requirements are:

Self-purification time.

  • The illuminance and irradiation time of ultraviolet sterilization.
  • The control of dust particles.

At present, most of the dynamic pass boxes on the market are the most basic power switch and the switch of the circulating fan, and even use the ordinary ones. 

And if the automatic control function of the transfer window is not set according to the user program, the staff may not be able to operate it by themselves. This way can implement the management indicators. The requirement of the self-cleaning time is 15 minutes, but in some cases, there are only 10 minutes. So it violates the regulations. The new version GMP requires the dynamic pass box cleaning time of 15 minutes, so it won’t open until the self-cleaning time runs out. And this will reach the GMP requirement.
