Clean room disinfection box VHP

hydrogen peroxydeautomatic

Product overview
This device enables safe, controlled transfer of materials between cleanrooms of different cleanliness classes while minimising the risk of cross-contamination.

Decontamination system based on VHP
The unit integrates a decontamination process based on vaporised hydrogen peroxide (VHP) to inactivate microorganisms on surfaces of transferred items, providing a validated high level of sterilisation.

VHP delivery via external hydrogen peroxide vapor generator
Decontamination is supplied from an external hydrogen peroxide vapor generator (e.g. Puriter) located outside the pass box, typically in a technical room or non-classified area. VHP is conveyed through a dedicated pipeline to ceiling nozzles that distribute the vapor evenly throughout the interior. Contaminated air is extracted via exhaust outlets connected to the facility HVAC system.

Maximum protection against escape of biologically active materials
The VHP Pass Box features tight-closing inlet and outlet doors with inflatable pneumatic seals to prevent release of biologically active materials in gaseous, liquid or solid form, ensuring containment between zones.

Tight-closing doors with inflatable pneumatic seal
Doors are designed for safe separation of rooms with different pressure regimes. Activation is controlled by a signal that engages the magnetic lock and inflates the perimeter pneumatic seal, creating an airtight closure. The seal remains pressurised until a separate control signal vents the seal and unlocks the door, allowing opening.
