HVAC-Integrated VHP System
Integrates a vaporized hydrogen peroxide (VHP) generator with the HVAC system; cycles can be developed and validated to a ≥6-log reduction target across rooms, airlocks and equipment surfaces. Hydrogen peroxide decomposes into water and oxygen, with a dry-cycle process designed for low corrosion risk under controlled conditions.
Aseptic Filling Isolator
A fully enclosed Grade A (ISO 5) barrier system for aseptic filling, stoppering and capping, with an integrated VHP bio-decontamination cycle that can be validated to a ≥6-log reduction target before every batch.
Sterility Test Isolator
A stable Grade A (ISO 5) environment for compendial sterility testing, protecting samples from false positives and operators from exposure, with an integrated VHP bio-decontamination cycle validated to a ≥6-log reduction target.
Open RABS (oRABS)
A restricted-access barrier system that maintains a positive-pressure, unidirectional-airflow Grade A zone over the filling and processing line.
VHP Pass Box
A wall-mounted transfer chamber with an integrated VHP bio-decontamination unit, for surface treatment between cleanrooms with cycles validated to a ≥6-log reduction target.
Cleanroom & VHP Sterilization Equipment
Five product series covering the full aseptic isolation, VHP bio-decontamination, material transfer & containment, air handling and personnel decontamination workflow.
CSPC Megalith Biopharmaceutical · HVAC-Integrated VHP System
Deeply integrates the VHP generator with the existing HVAC system, using its airflow circulation to distribute vaporized hydrogen peroxide evenly across sterile areas and duct interiors. Automated control handles preparation, injection, dwell, aeration and the return to production mode, reducing how often staff need to enter the cleanroom or move equipment.

How VHP Bio-Decontamination Works
Vaporized hydrogen peroxide (VHP) is a validated, standard bio-decontamination method in modern pharmaceutical manufacturing. A complete cycle distributes VHP vapor across the surfaces of an enclosed space — isolators, pass boxes, RABS, cleanrooms — and can be developed and validated to a repeatable ≥6-log reduction target; hydrogen peroxide decomposes into water and oxygen, with residual concentration reduced to a specified safety threshold after aeration.
Fenggu's VHP generation modules are built directly into isolators and pass boxes rather than added on afterward. Cycle time, injection rate and related process parameters can be controlled through predefined recipes, while VHP distribution and microbial reduction are confirmed through cycle development and validation.
Biosafety Airtightness Performance
In BSL-3/4 laboratories and other high-containment processes, airtightness is the last line of defense. Fenggu's airtight doors, biosafety pass boxes and isolation valves are all pressure-tested with high-density EPDM seals resistant to VHP, formaldehyde and chlorine dioxide. The figures below are measured test results, not marketing claims.

Common Questions on Selection & Working With Us
How do I choose between a Mobile VHP Room Bio-decontamination Unit and an HVAC-Integrated VHP System?
It mainly comes down to the size and number of rooms to be treated. A mobile unit suits a single, smaller space where flexibility to relocate matters. For multiple rooms or a large cleanroom area, an integrated system distributes VHP through the HVAC system, which can give better uniformity, repeatability and lower long-term labor. Tell us your room count and floor area and our engineers can help you decide.
Can equipment be customized to our existing facility and process?
Yes. External dimensions, materials (such as SUS304/SUS316L), the control system, VHP concentration and cycle parameters can all be adjusted to your process and facility conditions. The HVAC-integrated system is also available in 1,000/2,000/3,000 m³ and other capacities.
Do you provide installation, commissioning and validation support?
Yes. We provide on-site installation and commissioning, operator training, and can support your IQ/OQ validation work with the relevant technical support and documentation.
What information should I include when requesting a quote?
It helps to include the treatment volume or room layout, target cleanliness classification, your existing HVAC setup (if any), and what you need treated (rooms, equipment or materials). The more detailed the information provided, the more accurately we can recommend a suitable configuration and prepare a quotation.
