VHP solutions by application
Six engineering guides. Each explains why the application needs a VHP step, which equipment configurations fit, what to plan for in cycle design and validation, and what an engineer will ask you.
Material transfer & pass boxes
Every item that enters a Grade A/B zone is a contamination route.

Cleanroom & room decontamination
Shutdowns, changeovers, new-facility start-up and contamination events all call for a room-level sporicidal step.

Isolators & RABS
An isolator is only as good as the decontamination step that starts each campaign.

HVAC-integrated suites
When a whole suite — and the ductwork serving it — must be decontaminated, carrying VHP through the existing air handling system reaches every room from one fixed unit, instead of moving mobile generators room by room..

Biosafety labs & filter housings
Before a contaminated HEPA filter is changed, a biosafety cabinet is serviced or a containment lab is handed over for maintenance, the air path and surfaces must be decontaminated — with the containment boundary still intact..

Cell & gene therapy
Cell therapies cannot be terminally sterilised, and each batch is often a single patient.

| What you need to treat | Typical approach | Fenggu equipment |
|---|---|---|
| Materials crossing into Grade A/B | VHP pass box, or airlock for large loads | FG-PB-VHP · FG-VHP-AL250 |
| A single room up to 300 m³ | Mobile room generator | FG-VHP-M500 |
| A multi-room suite and its ductwork | HVAC-integrated system | FG-VHP-C1000 · C2000 |
| Isolator chambers | Integrated generator or generator port | Fenggu isolators |
| BSCs, centrifuges, enclosed equipment | Closed-loop recirculating generator | FG-VHP-GL |
| Lyophilizers, fermenters without SIP | Pulsed-vacuum generator | FG-VHP-G |
| BIBO HEPA filter housings | In-situ housing decontamination | FG-VHP-BIBO |
