Gaia Nanobubble Generators

Oxygen (O₂), ozone (O₃), carbon dioxide (CO₂), nitrogen (N₂) and hydrogen (H₂).

Ultrafine bubbles down to approximately 100 nanometres.

Ultrafine bubbles remain in solution for weeks after saturation, rather than the days typical of conventional aeration.

Above 80%, varying by gas type.

Yes. The generators are inline and connect to new or existing installations.

Yes. Ozone-compatible models use materials and components rated for ozone service.

Nanobubble generators for dissolving oxygen and other gases into water with very high efficiency.
