Engineered in Hefei.
By the team that helped define the science.
HPFN Tech is the civilian product arm of a hypoxic-engineering group with 20+ years of military R&D heritage. We design, manufacture, and ship every system from our facility in Hefei, Anhui — and we'd like you to come see it.
What HPFN Tech is, where the engineering comes from, and why being the manufacturer — not a reseller — matters.
HPFN Tech (Hefei Hypoxic Fitness Sports Technology Co., Ltd.) designs and builds normobaric hypoxic training systems for elite sport, military, wellness, research and personal applications. Every system shipped under the HPFN name is engineered and assembled at our facility in the High-Tech Industrial Development Zone of Hefei, Anhui — the same campus where the company's founding patents were developed.
Our engineering roots go back two decades, to a military hypoxic R&D program focused on pre-acclimatization protocols for tactical operations at high altitude. That program produced the closed-loop oxygen-control architecture, the safety-critical sensor design, and the protocol library that the current product line is built on.
HPFN Tech (Hefei Hypoxic Fitness Sports Technology Co., Ltd.) is the civilian product arm of Hefei Hengcheng Intelligent Technology Co., Ltd. — the engineering group that produced HPFN's founding hypoxic-air patents and supplied hypoxic acclimatization systems to Chinese military training programs for over two decades. HPFN Tech launched as the civilian-facing entity in 2019, and the official military-to-civilian product transition was reported to the Anhui Provincial Department of Commerce in November 2022. Today HPFN works directly with national teams, performance facilities, longevity clinics, and research institutions across Asia, Europe, and the Americas. We are the manufacturer of record — not a trading company, not a reseller.
From the military R&D program of 2003 to the commercial HPFN line of today — a continuous engineering lineage. (Milestone dates shown here are placeholders pending verification.)

Every HPFN system is engineered, assembled and tested in a single Hefei facility. Visitors welcome.
HPFN's manufacturing and R&D facility occupies 3,400 square metres in Hefei's High-Tech Industrial Development Zone. Every commercial system — Everest, Kilimanjaro, Matterhorn, Kailash — is assembled, calibrated and tested in this single facility before shipment.
Critical components (oxygen sensors, control electronics, software) are sourced from a small pool of qualified suppliers and verified against the same standards we apply to defense-grade hypoxic equipment. Every unit goes through a multi-stage QC cycle, including a full-system burn-in run at multiple altitude profiles before release.
We host buyer facility visits regularly. If you are seriously considering HPFN equipment, the most efficient diligence path is to come walk the floor. We will host you in Hefei, walk you through the build process, and let you see a system go through QC end-to-end.
HPFN holds the certifications that procurement teams will ask about. Certificate documents shown here are illustrative placeholders; full PDFs are available on request.
CMA
HPFN is the only hypoxic fitness manufacturer in China holding this certification.
CE
Required for sale in the European Economic Area; HPFN systems meet the applicable EMC and safety directives.
IEC 60601
Engineered to align with the safety profile required of medical devices, even though hypoxic training systems are generally regulated as fitness equipment.
Certification process opened in 2026 in preparation for North American market entry.
Four people you're most likely to interact with on an HPFN engagement, plus the wider team that designs and builds the equipment.
20+ years in hypoxic and respiratory engineering. Led the military R&D program that produced HPFN's founding patents.
Senior engineer on the original closed-loop hypoxic generator project. Holds 14 patents on hypoxic air generation and SpO₂ monitoring.
12 years in elite sport performance, previously with national-team endurance programs. Designs HPFN protocols and consults on customer deployments.
International business development across EMEA and the Americas. Speaks English, German, Mandarin. Leads HPFN's direct relationships with international clients.
The fastest way to evaluate HPFN — in person, in Hefei, with the engineers who built the equipment.
For serious prospects, an in-person facility visit is the fastest way to evaluate HPFN. You will meet the engineers who designed the equipment, see units come off the line, and run a working system through its full operating range.
HPFN is also active on the international trade-show circuit, with the equipment available for hands-on demos at every event. 2025 appearances included FIBO Cologne and Saudi Sports Expo. The 2026 schedule is published below as it firms up.
For everything else — questions, quote requests, partnership inquiries — the most direct path is to message us. We respond within 24 business hours.
Come see for yourself.
The most efficient diligence on HPFN is a day in Hefei. We'll host you on the floor, walk you through the build, and answer every question — engineering, commercial, or strategic.
