Oxygen Tanks and Regulators

Every oxygen-fed ozone generator needs an oxygen source, and sourcing a tank is the single most common sticking point for new equipment owners. This section exists to remove it.

These articles cover how to actually get an oxygen tank in North America (including what to say to a supplier), how regulators work and which fitting standard you need (540 vs. 870), why low-flow regulators matter for accurate ozone concentrations, and the honest trade-offs between oxygen tanks and concentrators. High-purity oxygen isn't a marketing flourish: the feed gas determines both the concentration range and the purity of the ozone produced, which is why our concentration charts are specified against pure oxygen at defined flow rates.

If you buy a kit from us, we'll find local oxygen suppliers for you as part of setup - but the knowledge here is useful whoever you buy from.
