VHP Sterile Pass Box for Cleanrooms

● Sterilization cycle takes less than 120 minutes, enabling multiple batches of sterilization operations within a single day.

● Adopts clean compressed air as the power source, reducing indoor air extraction, accelerating dehumidification, shortening total sterilization time, and lowering the risk of condensation inside the chamber.

● Equipped with a decomposition filter that effectively reduces VHP concentration during exhaust, minimizing impacts on the environment and personnel.

● Features top-and-bottom accessible maintenance design, reducing required maintenance space.

● Supports rotational sterilization and transfer, enhancing plant space utilization and optimizing process layout.

● Chamber tightness testing is available; sterilization process can only start after passing the test.

● Requires batch number input before sterilization for easy traceability.

● Sterilization effect complies with GMP requirements.

The VHP Sterile Pass Box represents a breakthrough in material transfer technology, specifically engineered to enhance safety and efficiency in controlled environments. By leveraging vaporized hydrogen peroxide (VHP) sterilization, it sets a new standard for maintaining sterility during material movement between different cleanliness zones.

At the core of this innovation is its advanced VHP sterilization system, which delivers rapid and thorough disinfection. This system releases hydrogen peroxide vapor in a controlled manner, eliminating a broad spectrum of microorganisms—including bacteria, viruses, and spores—from the surfaces of materials. This level of sterilization ensures that even the most sensitive items remain uncontaminated when entering high-grade clean areas.

User-friendliness is a key design focus. The pass box features an intuitive interface that simplifies operation, making it accessible to both skilled technicians and new operators. A transparent viewing window allows real-time monitoring of the sterilization process without compromising the sterile environment inside. Its spacious work area accommodates a wide range of items, from small tools to larger equipment, eliminating the need for disassembly during transfer.

Versatility is another standout feature. The pass box can be customized to fit specific cleanroom layouts, with modular design options that enable seamless integration into existing structures. Whether installed as a standalone unit or embedded into walls or partitions, it minimizes disruption to workflows and saves valuable floor space. This adaptability makes it suitable for diverse industries, including pharmaceuticals, biotechnology, and advanced research laboratories.

Safety is prioritized through multiple mechanisms. An interlock system prevents both doors from opening at the same time, maintaining the integrity of the sterile environment. Rounded edges and smooth surfaces reduce the risk of accidental injury during operation and cleaning, while the decomposition filter ensures safe exhaust of VHP, protecting both personnel and the surrounding environment.

Efficiency is optimized to boost productivity. The fast sterilization cycle—under 120 minutes—allows for multiple batches per day, reducing downtime and accelerating workflow. The use of clean compressed air for dehumidification further shortens processing time, while the option for rotational sterilization enhances space utilization in facilities.

In summary, the VHP Sterile Pass Box combines cutting-edge sterilization technology, user-centric design, and robust safety features to redefine material transfer in controlled environments. It not only meets strict GMP standards but also adapts to the unique needs of modern cleanrooms, ensuring reliable sterility, operational efficiency, and peace of mind for users across critical industries.
