Static Pass Box Manufacturer in India

Static Pass Box, also known as Pass-Through

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.

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.

Static pass boxes transfer materials between two rooms of equal cleanliness and are designed for minimal personnel movement. Static pass boxes are ideal when ventilation is not required – primarily for moving non-sensitive products between two cleanrooms of equal cleanliness. Static pass boxes must never be used to transfer material between clean and non-clean rooms.
