Dynamic Pass box, Also known as Pass-Through

Those who work in cleanrooms know it well: avoiding cross-contamination between rooms with incompatible cleanroom classifications is essential to preserve the desired ISO classification and maintain the integrity of products and processes. One way to achieve this is by minimizing material movement.

Non-viable particles and microorganisms can cause contamination in a cleanroom due to the entry and exit of materials within the controlled environments. With this in mind, designing and correctly installing material transfer equipment is necessary.

A pass box’s primary and only work is to pass materials from one side to the other, between controlled environments of different classes, to avoid airborne cross-contamination. Should any particulate matter be present on the surface of the material being transferred, it is swiped away during the operation. The prime feature of a pass box is the interlocking door mechanism – when the door on one side is open, the door on the other remains closed.

• Dynamic pass boxes transfer materials from uncontrolled to controlled environments. A dynamic pass box works like an airlock or laminar airflow unit.
• Usually, Dynamic Pass Boxes are placed at Grade “D”, Grade “C”, Grade “B” as well as Grade “A”.
• It is usually Mounted on Panel/Wall or the Floor.
• Panel/Wall Mounted Passbox are suitable for transferring materials that are handy and not large enough.
• Floor Mounted Passbox is used for large Transfer materials.
• UV Lights help kill present bacteria inside the pass box while loading and unloading material.
