Overview
The Fenggu Automatic-Door VHP Pass Box combines vaporized hydrogen peroxide surface bio-decontamination with automatic door control for material transfer between controlled environments. Motorized door operation reduces manual contact and supports repeatable transfer workflows in pharmaceutical, biosafety and healthcare facilities.
The integrated system monitors critical process conditions, records cycle data and reduces residual hydrogen peroxide through catalytic decomposition before door release. The two doors are interlocked so they cannot be opened simultaneously.
Key Features
- Automatic door opening and closing with safety interlocking
- VHP surface bio-decontamination with a documented 6-log reduction target
- Inflatable or mechanical sealing configuration according to project requirements
- Monitoring of temperature, humidity and hydrogen peroxide concentration
- Catalytic decomposition to reduce residual hydrogen peroxide to ≤1 ppm
- H14 HEPA-filtered inlet and outlet air paths
- Siemens PLC automatic control and cycle data recording
