How the selector decides
The selector maps the space to an equipment type using the capacities published on fenggu-bio.com:
| What is treated | Equipment type | Published range |
|---|---|---|
| Single room or area | Mobile VHP room sterilizer (FG-VHP-M500) | Up to 300 m³ per unit |
| Suite served by an AHU | HVAC-integrated VHP (FG-VHP-C1000 / C2000) | 1,000 m³ / 2,000 m³ standard; larger configured per project |
| Isolator | Isolator with VHP bio-decontamination (FG-ISO series) | Chamber volume of the isolator |
| Small items into a clean area | VHP pass box (FG-PB-VHP) | Items that fit the chamber |
| Pallets and equipment | Airlock with integrated VHP (FG-VHP-AL250) | Walk-in airlock; full cycle < 60 min |
| HEPA filter housing | VHP BIBO sterilizer (FG-VHP-BIBO) | Enclosed volumes up to 30 m³ |
| Enclosed equipment | Recirculating VHP generator (FG-VHP-GL) | Closed loop with the equipment |
What volume alone does not tell you
Volume is the first filter, not the answer. Two spaces of the same size can need different setups because of how well they can be sealed, how the HVAC is arranged, what materials are inside, how often they are treated and how quickly they must be back in use. Those are the questions the selector lists with each result, and the ones an engineer will ask before recommending a configuration.

Common questions
Which VHP equipment do I need for a room?
A single room up to 300 m³ is within the range of one mobile VHP room sterilizer. Larger rooms or several rooms on one AHU are usually better served by an HVAC-integrated system, or several mobile units with distribution mapping.
When is an HVAC-integrated VHP system better than a mobile unit?
When a whole suite on the same air handling unit is decontaminated routinely. The vapour is distributed through the existing ductwork, so rooms are treated together without moving equipment and sealing each room separately.
How do I bring materials into a clean area with VHP?
Items that fit a chamber go through a VHP pass box. Pallets, trolleys and equipment go through an airlock with integrated VHP, which runs as a normal airlock between cycles.
Is the selector result a quotation?
No. It shows the type of equipment that fits the published capacity. The configuration is confirmed by an engineer from your layout, materials and requirements.
