HVAC-Integrated VHP System
A fixed, central vaporized hydrogen peroxide system that couples to the existing air-handling plant to distribute VHP through the cleanroom and its ductwork. Standard capacities are 1,000 m³ and 2,000 m³; larger capacities can be customized.

Overview
The Fenggu HVAC-Integrated VHP System deeply integrates a hydrogen-peroxide biodecontamination unit with the existing air-conditioning plant. Using the HVAC air-circulation loop, it distributes vaporized hydrogen peroxide evenly through the target space and the ductwork itself, and the strong oxidising action of H2O2 damages the cell membranes, proteins and nucleic acids of micro-organisms, supporting broad-spectrum antimicrobial activity (sporicidal efficacy subject to validation). After biodecontamination the residual peroxide decomposes into water and oxygen, leaving no toxic by-products. The unit connects directly to existing air-handling units without major modification, forming a closed loop through C-PVC piping. Standard capacities are 1,000 m³ (FG-VHP-C1000) and 2,000 m³ (FG-VHP-C2000); larger capacities of 3,000 m³ and above are available as project-specific configurations.
Key Features
- Distributes VHP through the HVAC ductwork to biodecontaminate whole rooms and the connected air system
- Flash-vaporizes 30–35% H2O2 into a fine vapor that penetrates ductwork and HEPA filters
- Standard 1,000 m³ and 2,000 m³ capacity models; 3,000 m³+ available as a project-specific configuration
- Dry-process, low-corrosion method designed for compatibility with common cleanroom and ductwork materials
- 12-inch industrial touchscreen with real-time monitoring of time, temperature, humidity and H2O2 concentration; PLC closed-loop concentration and residual control
- Low-temperature process (4–80 °C), fully automatic, with FDA 21 CFR Part 11 audit-trail compliance
