Passbox

A Pass Box is a cleanroom equipment designed to transfer materials, documents, tools, and components between two controlled environments without allowing personnel movement or compromising cleanliness levels. It acts as a contamination control barrier, minimizing the entry of dust, particles, and microorganisms into clean areas.

Pass Boxes are widely used in pharmaceutical manufacturing, biotechnology facilities, hospitals, laboratories, electronics manufacturing, food processing plants, and other industries where maintaining a controlled environment is critical. The system is equipped with an interlocking mechanism that ensures only one door can be opened at a time, preventing direct airflow between adjacent rooms and reducing the risk of cross-contamination.
