Dual Access Doors: Passboxes have doors on both sides, typically interlocked to prevent both doors from being open simultaneously. This minimizes the risk of contaminants entering the cleanroom.
Material Construction: They are usually made from materials that are easy to clean and resistant to corrosion, such as stainless steel or powder-coated steel.
Airflow Control: Some passboxes include hepa filters to maintain cleanliness during transfer. They may also have features like air showers to remove particles from materials before they enter the cleanroom.
Size And Design: Passboxes come in various sizes to accommodate different types and sizes of materials. They can be wall-mounted or floor-standing, depending on the layout of the cleanroom.
Usage: Operators use passboxes to transfer items such as equipment, tools, or materials into and out of the cleanroom without compromising its controlled environment.
