Latest company case about Guangzhou Cleanroom Construction Co., Ltd. Certifications

Pass Box is a specialized device designed for material transfer between cleanrooms, or between cleanrooms and non-clean areas. Its primary purpose is to enable the safe and efficient transfer of materials without compromising cleanroom pressure differentials or cleanliness control, thereby effectively reducing contamination risks caused by frequent personnel movement.

Pass boxes are typically installed within cleanroom partition walls. Both doors are designed with an interlocking mechanism, ensuring that only one door can be opened at a time during material transfer. This structure prevents air exchange and cross-contamination, helping maintain a stable and controlled cleanroom environment.

Pass boxes are widely used in industries such as pharmaceuticals, biotechnology, electronics manufacturing, food processing, hospitals, and laboratories. They are commonly applied for transferring raw materials, semi-finished products, tools, and samples, and serve as an essential auxiliary component of cleanroom systems. With proper selection and standardized installation, pass boxes can significantly improve cleanroom operational efficiency, reduce energy consumption, and enhance overall environmental stability.
