A pass box, also known as a transfer chamber or pass-through box, is a piece of equipment commonly found
in cleanrooms, laboratories, and other controlled environments. It serves as a secure and contained way to
transfer materials between two spaces with different levels of contamination control.The basic principle of
a pass box is to prevent direct contact between the two areas and reduce the potentialfor cross-contamination.
Items are placed into the pass box from one side, the door is closed and then, typically through an interlocking
mechanism, the door on the other side can be opened to retrieve the items, ensuring that there is no direct
airflow or material transfer between the rooms.
1.Interlocking Doors: Pass boxes usually have doors on both sides that operate with an interlock system. This
means that when one door is open, the other remains locked to prevent air exchange between the two environments.
2.HEPA Filters: Dynamic pass boxes often incorporate High-Efficiency Particulate Air (HEPA) filters to maintain a
clean airflow within the pass box. These filters remove particles down to extremely small sizes, helping to minimize
contamination risks.
3.UV Light Sanitization: Some pass boxes have built-in ultraviolet (UV) lights for sterilizing the interior before
and after each use. UV light kills bacteria, viruses, and other microorganisms that might contaminate the transferred
materials.
4.Laminar Flow: Advanced pass boxes can provide laminar flow, which ensures a steady, unidirectional flow of
filtered air across the work area to further minimize contamination.
5.Construction Material: They are usually made of stainless steel for durability, ease of cleaning, and resistance
to corrosion.
6.Size and Design: Pass boxes come in various sizes to fit different requirements and can be floor-standing or
wall-mounted.
