2. In order to solve the problem of contamination when any materials are required to be
transferred into facilities such as clean rooms, Airtech comes out with a solution of
using a pass box. Clean rooms are usually designed such that the need for personnel
to enter and exit is minimized to reduce contamination.

box is usually installed on the walls of the clean room to act as a temporary storage
area to transfer any materials into or out of the clean room.

4. The pass box has a mechanism to prevent operators from opening both of the doors at
the same time. This helps to prevent the integrity of the clean room from being
compromised. The pass box has a phone for operators on opposite sides to speak to
each other when the items are to be transferred in or out of the clean room.

5. The doors on the pass box are transparent which allow personnel to have a clear view
of the internal enclosure. The clean auto pass box is built with the concept of what a
normal pass box can do and provide automation of items to be transported from one
room to another.

each end, high-efficiency particulate arrestance (HEPA) filter, fan and a roller
conveyor. It is particularly useful in scenarios where high volume and frequency are
required. This automation improves efficiency in terms of time and manpower.
