About Brown Gas
H₂ + O₂ Combined
Brown gas is a 2:1 mix of hydrogen and oxygen produced by water electrolysis — the natural output before gas separation.
3-Speed Control
Start at 300 mL/min and progress at your own pace — important for new users or those sensitive to high H₂ doses.
SPE/PEM Quality
Solid polymer electrolyte membrane produces clean, dry gas — no impurities from electrolyte additives.
Home or Clinic
At 10.5 kg, this unit is designed to stay in one place — ideal for a dedicated therapy area at home or a small clinic.
Want Pure H₂ Instead of Brown Gas?
The Q2S-300 delivers 99.99% pure hydrogen without oxygen — a different therapy profile.
