A pure-hydrogen machine and a hydrogen-oxygen machine should not be compared by the largest flow number alone. Distributors need to distinguish gas composition, hydrogen flow versus total mixed-gas flow, outlet design, humidification, water requirements, safety documentation and intended market position.
The core configuration difference
A pure-hydrogen machine delivers the hydrogen generated at the PEM/SPE cathode through its designated outlet. A hydrogen-oxygen integrated machine manages hydrogen and oxygen streams generated on opposite sides of the electrolysis membrane and provides the model’s specified combined delivery arrangement.
For the Youborui HO1000 family, the catalogue specification is 1,000 mL/min total gas output at an approximately 2:1 hydrogen-to-oxygen ratio—the stoichiometric volume relationship created by splitting water. This should not be rewritten as 1,000 mL/min of hydrogen.
Current Youborui model comparison
| Model | Gas format | Catalogue output | Buyer focus |
|---|---|---|---|
| H300 | Hydrogen only | 300 mL/min hydrogen | Entry distributor range, compact format and current accessories. |
| H600 | Hydrogen only | 600 mL/min ±5% hydrogen | Higher pure-H2 flow, 280 W reference configuration and water monitoring. |
| HO1000 | Hydrogen + oxygen | 1,000 mL/min total, 2:1 H2/O2 | 310 W, AC 220 V/50 Hz reference version and dual-gas architecture. |
| HO1000L | Hydrogen + oxygen | 1,000 mL/min total, 2:1 H2/O2 | Alternative enclosure, champagne-gold catalogue colour and current accessories. |
Specifications above come from current manufacturer reference files and must be reconfirmed in the quotation. Gas-purity figures should be treated as model performance specifications only when a current, traceable measurement supports them.
Five comparisons that prevent expensive misunderstandings
1. Hydrogen flow versus total gas flow
Always label the denominator. A 1,000 mL/min hydrogen-oxygen total output is not directly comparable to 600 mL/min of hydrogen-only output.
2. Separate gas paths and humidification
Ask for a gas-path diagram showing generation, separation, gas-water management, humidifier bottles, outlets and the point at which streams are combined. Check that the delivered accessories match the manual.
3. Water and maintenance
Both configurations depend on approved purified or distilled water, correct filling and scheduled maintenance. Obtain written instructions for reservoir cleaning, separators, humidifiers, tubing and long-term storage.
4. Electrical and destination-market configuration
Confirm voltage, frequency, plug, cord, power rating and labels. The HO1000/HO1000L files reviewed for this guide list AC 220 V/50 Hz and 310 W; other market versions must be confirmed rather than assumed.
5. Intended use and claims
Do not claim that oxygen inclusion, a higher flow or a particular ratio treats a disease. A review of clinical molecular-hydrogen research shows a growing but heterogeneous evidence base. Product-specific benefits require product-specific evidence and regulatory authorisation.
Which format fits a distributor?
Pure-hydrogen models can fit catalogues that need a clearly defined hydrogen-only product at different flow tiers. Hydrogen-oxygen machines can fit buyers specifically requesting water-electrolysis mixed-gas equipment and willing to manage the additional gas-path, accessory and documentation questions. The commercial decision should consider local classification, operator training, price level, service capability and customer expectations.
Frequently asked questions
Is 1,000 mL/min on HO1000 all hydrogen?
No. It is total hydrogen-oxygen output specified at a 2:1 volume ratio.
Is a hydrogen-oxygen machine automatically better?
No. It is a different configuration. “Better” depends on lawful intended use, verified performance, documentation and buyer requirements.
Can I use tap water?
Use only the purified or distilled water stated in the current model manual.
What should I request before ordering?
Current specification, gas-flow definition, gas-path diagram, manual, accessories, label, electrical version, test documents, warranty and spare-parts process.

Request a model-specific OEM/wholesale quotation
Send Youborui your destination country, sales channel, expected quantity, required voltage and plug, private-label needs, packaging language and required documents. We will match the request to the current pure-hydrogen or hydrogen-oxygen machine configuration rather than quoting from a generic catalogue description.
