HAH 900

The HAH 900 (model Q2S-900) is a hydrogen inhalation machine from Health and Hydrogen (HAH). It makes hydrogen and oxygen by electrolysis of water using SPE and PEM technology, with separate H2 and O2 outlets on the side.

Total flow is 900 mL per minute, which HAH lists as 600 mL/min of hydrogen and 300 mL/min of oxygen, with a hydrogen purity of 99.99%. HAH's brochure lists one-click operation, adjustable flow rate, a timer from 1 to 8 hours, and hydrogen-only, oxygen-only and combined oxy-hydrogen output modes. HAH also lists making hydrogen water with a hydrogen rod as a function.

The unit measures 300 x 193 x 285 mm and weighs 6.5 kg. It runs on AC 220 V or 110 V, 50 Hz, works at 5 to 40 °C and up to 80% relative humidity, and uses double-distilled or pure water.
