HAH 1800

The HAH 1800 (model Q2S-1800) 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 adjustable to 900, 1200 or 1800 mL per minute. At the top setting, HAH lists 1200 mL/min of hydrogen and 600 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. The control panel also shows water volume and TDS monitoring and a day/night mode. HAH lists making hydrogen water with a hydrogen rod as a further 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.
