How ozone therapy works
What does an oxygen concentrator actually do, and why is one part of the system?
An oxygen concentrator draws in room air and passes it through molecular sieve beds that hold back nitrogen, delivering a continuous stream of concentrated oxygen. Every concentrator we supply with an ozone sauna is a 5 litre per minute medical unit producing 93% oxygen, plus or minus 3%. The sauna's ozone generator runs on that oxygen.
The mechanism
A concentrator is not a tank and does not store gas. It compresses ambient air and pushes it through molecular sieve beds — porous crystalline material, usually a zeolite, whose uniform pore size traps nitrogen and lets oxygen pass — then cycles between beds so the output is continuous. Our concentrator specifications list compressed packed molecular beds, 24-hour continuous operation, a five-channel oxygen filter, an oil-free compressor, an alarm function and an optional oxygen purity alarm.
Unless we have specified otherwise for your order, every unit we supply is 5 litres per minute at 93% oxygen purity, plus or minus 3%. The oxygen concentrator supplied with the sauna is a medical device in its own right. The model we currently supply is FDA-cleared and CE marked. The FDA clearance applies to the concentrator, not to the sauna.
Its role in an ozone sauna
The concentrator does two jobs at once:
- It supplies the feed gas. The ozone generator inside the cabinet converts that oxygen into ozone.
- It sets the flow rate. The oxygen feed runs at a constant 2 litres per minute. With a 500 mg/h generator on that feed, the ozone concentration in the sauna’s air volume is about 47 ppm, varying a little with the size and build of the person inside.
If too little oxygen passes over the generator, the sauna’s airflow alarm sounds; the remedy is to increase the flow on the concentrator. Running the sauna with the concentrator off will damage the generator.
Concentration and output are different measurements
Parts per million is a ratio — how much ozone is present in a given volume of air. Milligrams per hour is a mass produced over time. Both belong on a specification sheet, together with the flow rate, and a figure quoted without the other two is not comparable between devices.
Safety around oxygen
Open flames must not be brought near oxygen sources, though a candle burning elsewhere in the same room is not a fire risk. Clean up spilt water, particularly near the concentrator or electrical wiring.
