Pass box—also known as pass-through, or transfer hatch—is a critical cleanroom component. Why? In this article, VCR will provide 3 key advantages of using pass box in clean room.

I. Clean room pass box advantages

1. Pass box reduces contamination risk and is labor-saving

Pass box is an affordable and easy-to-install way to protect the cleanroom environment and meet industry safety standards. In addition to preventing external contaminants from entering the cleanroom, they reduce the number of workers in the room at any given time and limit the frequency of room entries and exits. Both of these things help to further reduce the risk of contamination.

2. Pass box is time-saving and boosts productivity

Integrating a pass box also means cleanroom personnel does not need to shower and gown up to place or remove materials from the cleanroom. This saves time and, ultimately can increase productivity.

3. Pass boxes are varied

Pass box is durable, easy to clean and maintain. Additionally, they are highly customizable, coming in a range of materials, sizes, and designs to meet different cleanroom needs. For example, they are available with fireproofing for combustible material handling and with HEPA air filters for highly sensitive product manufacturing.

  • Aerospace
  • Computer manufacturing
  • Electronics and technology
