HVAC-Integrated VHP System
Vaporized hydrogen peroxide bio-decontamination built directly into your HVAC system — a reproducible 6-log reduction across rooms, airlocks and equipment, dry and residue-free once aeration is complete.
Aseptic Filling Isolator
A fully enclosed Grade A (ISO 5) barrier for sterile filling, stoppering and capping. Integrated VHP bio-decontamination delivers a validated, residue-free 6-log reduction before every campaign.
Negative Pressure Isolator
A sealed negative-pressure barrier that protects the operator and environment when handling potent, cytotoxic, sensitizing or infectious materials — inward airflow with single-pass HEPA exhaust for OEB4/OEB5 containment.
Sterility Test Isolator
A stable Grade A (ISO 5) environment for pharmacopoeia sterility testing — protecting the sample from false positives and the operator from the tested product, with integrated VHP 6-log decontamination.
Open RABS (oRABS)
A restricted-access barrier system providing a Grade A zone with positive-pressure laminar flow over aseptic filling and processing lines.
VHP Pass Box
Wall-mounted transfer chamber with integrated VHP for residue-free 6-log surface decontamination between classified areas.

See all →How VHP Bio-Decontamination Works
Vaporized hydrogen peroxide (VHP) is the standard for validated bio-decontamination in modern pharmaceutical manufacturing. A VHP cycle distributes hydrogen peroxide vapor evenly across every surface of an enclosed space — isolators, pass boxes, RABS and cleanrooms — achieving a reproducible 6-log reduction of microbial contamination, with no chemical residue once aeration is complete.
At Fenggu, VHP generation is integrated directly into our isolators and pass boxes rather than added as an afterthought — giving operators precise control over cycle time, concentration and distribution.
Biosafety Airtight Sealing
In BSL-3/4 laboratories and containment suites, airtightness is the last line of defense. Fenggu gastight doors, biosafety pass boxes and containment valves are built and pressure-tested to hold — with high-density EPDM seals resistant to VHP, formaldehyde and chlorine dioxide. These are measured, verifiable numbers, not marketing claims.

Frequently Asked Questions
How do I select the right isolator for my application?
Isolator selection depends on your process risk and containment goal. Aseptic isolators protect the product in sterile filling and compounding; cRABS suit aseptic filling lines that need frequent operator interaction; OEB (high-containment) isolators protect operators when handling potent or toxic compounds. Share your process, OEB level and throughput, and our engineers will recommend a configuration.
Are your systems cGMP and FDA compliant?
Yes. Our isolators, VHP systems and pass boxes are designed and documented to cGMP requirements and FDA expectations, including material traceability, HEPA H14 filtration and full validation documentation (IQ/OQ support available).
Do you provide installation and validation support?
Yes. We support the full lifecycle — design, manufacturing, factory acceptance testing (FAT), on-site installation, and validation documentation to help your team complete IQ/OQ/PQ.
Do you export and support overseas projects?
Yes. We have experience with international delivery, export documentation and remote/on-site commissioning support for pharmaceutical clients in overseas markets.
