What is a Pass Box?

A Pass Box, also known as a Pass Through Box, is a cleanroom equipment used to transfer materials between two areas of different cleanliness levels without allowing contaminants to enter the controlled environment. It ensures operational efficiency, reduces material handling errors, and maintains sterility in critical processes.

Types of Pass Boxes

  • Static Pass Box – Used where material is transferred between clean but same-grade areas, without airflow requirements.
  • Dynamic Pass Box – Equipped with HEPA filters and blower units for air circulation, ensuring contamination-free transfer between areas of different cleanliness grades.
