Passbox / Transfer hatch / Pass through hatch
Passbox / Transfer hatch / Pass through hatch / 傳遞箱 is specially designed for the transfer of materials in controlled environments. It is built with high quality stainless steel. It has two doors with inspection window and a mechanical or electromagnetic access management system. The pass box / transfer hatch can be integrated easily into walls and can be supplied as an independent unit or as a unit that connects to existing utilities.
Pass boxes / Transfer hatches / Pass through hatches are double-door box-shaped devices that are used when materials are brought into the clean room. Similar to Air Showers, they are structured so that both doors cannot simultaneously be open, so they function as an airlock insulating the Cleanroom from the outside air. Models featuring Air Shower functions and models featuring Clean Unit functions are also available, which are Air Shower Passboxes / 風淋傳遞箱.

The Main Features of Our Passbox / Transfer hatch / Pass through hatch / 傳遞箱
“Increased efficiency: Pass box / Transfer hatch helps to increase efficiency by minimizing the number of times personnel need to enter the clean room environment. This reduces the risk of contamination and ensures that personnel can focus on their tasks without being interrupted by the need to gown up and enter the cleanroom environment.
Dual doors: A transfer hatch typically consists of two sets of doors that create an interlocking barrier. This prevents both spaces from being accessed at the same time.
Interlock mechanism: Pass box / Transfer hatch has interlocked doors that prevent both doors from being open at the same time, reducing the risk of contamination.
Sterilization: Some pass boxes include ultraviolet (UV) light to sterilize the materials being transferred.
HEPA filters: Air shower passboxes are equipped in-house-developed pulse jet nozzle with high-efficiency particulate air (HEPA) filters that remove particles and contaminants from the air entering the passbox. This helps to ensure that the air in the passbox is clean and free of contaminants.
Compatible with overseas properties as well. Based on the standard specifications, we offer specifications in line with customer requests.”
Passbox / Transfer hatch / Pass through hatch / 傳遞箱 Applications
“Nuclear and radioactive materials handling: Passboxes / Transfer hatches are used in nuclear and radioactive materials handling to transfer materials between controlled environments of different levels of radiation exposure. This helps to prevent the spread of radioactive contaminants and maintain worker safety.
Aerospace manufacturing: Air shower passboxes are used in aerospace manufacturing to transfer materials between cleanroom environments of different cleanliness levels. The air shower helps to remove particles and contaminants from personnel and materials before they enter the cleanroom environment, ensuring the quality and reliability of sensitive components and systems used in aircraft and spacecraft.
Cleanroom packaging: Air shower passboxes are used in clean room packaging operations to transfer materials between cleanroom environments of different cleanliness levels. The air shower helps to remove particles and contaminants from personnel and materials before they enter the cleanroom environment.
Transfer hatches are installed in Cleanrooms and anterooms, and they possess systems to prevent dust from being brought into the clean room.
Transfer hatches and Air Shower Pass Boxes are widely used in plants for semi-conductors and liquid crystal devices, manufacturing plants for electronic or precision machine parts and materials, hospitals, biotechnology research, university laboratories, food plants and more.”
