Pass Box

What is a Pass Box?

A Pass Box is a specialized enclosure installed between two adjacent rooms of different cleanliness levels. Its main function is to transfer materials while preventing the entry of airborne contaminants. By limiting direct human movement between rooms, it helps maintain the controlled environment of cleanrooms.

Pass Boxes are typically available in two types:

1.      Static Pass Box – Used to transfer non-sensitive materials between clean and non-clean areas without airflow systems.

2.      Dynamic Pass Box – Equipped with HEPA filters and ventilation systems for transferring sterile or sensitive materials under clean airflow conditions.

Both designs are widely used across industries, depending on the level of cleanliness required.

Importance of Pass Boxes in Cleanroom Operations

Cleanrooms are designed to maintain extremely low levels of particulates. Any breach in their cleanliness can compromise product quality, research outcomes, or patient safety. A Pass Box addresses this by:

·        Preventing Contamination: Ensures materials enter cleanrooms without carrying dust, microbes, or other contaminants.

·        Maintaining Air Pressure: Supports controlled pressure differentials between rooms to maintain sterile airflow.

·        Reducing Personnel Movement: Minimizes unnecessary entry of staff into cleanrooms, thereby reducing contamination risk.

·        Ensuring Compliance: Meets regulatory standards like GMP and ISO, critical for pharmaceuticals and healthcare facilities.

For industries where even a small particle can cause significant damage, a reliable Pass Box is not optional—it is essential.
