The AquaCure AC50: Full Specs, Safety Engineering, and Why It's Worth It
The AC50 is a premium investment — here's exactly what that investment buys: the full spec sheet, the safety engineering behind it, and the warranty and return terms that back it up.
Full Specifications
What's under the hood
The AC50 uses alkaline electrolysis (not PEM) with a mild sodium hydroxide electrolyte to produce Brown's Gas — a mixed ~66% H₂ / 33% O₂ gas, not separated pure hydrogen. That distinction matters for how you think about the inhalation protocol specifically (more in How It Works).
| Technology | Alkaline electrolysis (NaOH electrolyte), variable-frequency output with digital display |
| Gas output | Up to 50 L/hour (~833 mL/min) of Brown's Gas (mixed H₂/O₂) |
| Power | ~250W; 120V or switchable 120V/240V (+$300) |
| Dimensions / weight | 12" x 12" x 9", ~16 lbs |
| Rated service life | 20+ years, designed for continuous 24/7/365 operation |
| Maintenance | Rinse cycle every ~100 hours, tracked via built-in hour meter |
| Certifications | CE base standard, upgraded to CSA/UL and Australian standards; every unit factory-tested before shipping |
The AC50's chassis is a customized, imported alkaline electrolyzer platform — Eagle-Research's value-add is the safety engineering and certification layer built on top of it, not a proprietary reactor design. That's not a knock; it's just useful context for the price.
Safety Engineering
This is where the AC50 actually earns its price premium
Unmodified stock units in this category commonly run 15–20 psi internally. Eagle-Research's stated target for the AC50 is roughly 2–3 psi — about an order of magnitude lower.
Pressure & shutoff systems
- Electrical over-pressure cutoff at ~2 psi
- Mechanical gas relief valve at ~3 psi
- Low-liquid and high-liquid automatic shutoff
- Master switch disconnects both power and neutral
Gas handling
- Anti-backfill check-valve system
- Tower-cap pre-scrubber settles lye mist before output
- Humidifier stage strips residual NaOH from gas
- Hour meter drives a scheduled ~100-hr rinse cycle

Who gets the most out of the AC50
✓ Good fit if you...
- Want more than one delivery method (water, inhalation, topical) from one machine
- Weight safety engineering and certification heavily in a purchase this size
- Plan to use it daily, long-term — the per-day cost drops fast on a 20-year-rated unit
- Are comfortable with routine maintenance (electrolyte refills, periodic rinsing)
Worth knowing before you order
- If you only need drinking water, not inhalation or topical use, the versatility is still there when you're ready to expand into it
- Plan for periodic maintenance — electrolyte refills and a rinse cycle every ~100 hours
- Molecular hydrogen research is real but still early — see The Science for the honest framing
- Financing (PayPal Pay Later, Affirm) is available if you'd rather spread out the $2,699+ price point
