Overview
The Fenggu Floor-Standing VHP Pass Box integrates a vaporized hydrogen peroxide bio-decontamination system with a large transfer chamber. It is intended for surface bio-decontamination of materials that cannot tolerate high-temperature treatment before transfer into Grade A/B or other controlled areas.
A Siemens PLC coordinates the chamber and VHP process for automatic, unattended cycles after validated parameters are entered. Interlocked, inflatable-seal doors help maintain separation between the two sides throughout the cycle.
Key Features
- Floor-standing chamber configuration for trolleys, drums and bulky equipment
- Double-door arrangement with inflatable seals and interlocking
- H14 HEPA-filtered inlet and outlet air paths
- Real-time monitoring of temperature, humidity, pressure and hydrogen peroxide concentration
- Siemens PLC automatic control with process status indication
- Cycle parameter printing for batch records and traceability
