What is an Oxygen Concentrator?

Dear Roger,
An oxygen concentrator is a small machine composed of a compressor, a sieve bed, an oxygen holding tank, a valve system, and a flow meter.

Air is taken in and compressed into the sieve bed, which has a very fine powder in it. Oxygen passes through, and nitrogen is held back. The oxygen goes into the holding tank and the nitrogen is released back into the atmosphere, with an audible exhalation. Then the cycle is repeated.

Oxygen with a purity of 95% is released from the holding tank in a steady stream, at a rate determined by the flow meter.

This technology was developed by NASA during the 1960s, and it works very well. Older units are noisier and bigger, and have higher flow rate meters on them, which are less useful for ozone production. The new units we have now are very small (toaster size) and very quiet, and have flow meters that give very low flow rates, which is just what we want. All ozone applications are possible, except for injection, when you require 99% pure oxygen.

Using an oxygen concentrator makes you independent of any outside control, the ultimate in convenience. It is the perfect companion to the ozone sauna, which requires large quantities of oxygen (typically 1/2 l/m).

A concentrator is also inherently safer than a pressurized oxygen tank.

Dear Dennis and Erma,

1/32 = .03125
1/16 = .06250
1/8 = .12500
1/4 = .25000
1/2 = .50000

These are the common flow rates for regulators in North America.

However, the rest of the world uses metric and you will usually only find concentrators with air flow meters that are calibrated that way.

.05
.10
.20
.30
.40
.50

So there is not a direct correlation betyween the two. However, it makes little difference. Insufflation of all types works fine at .05 and .10 l/m.

Best of health!

ONLY cold plasma ozone machines work with an oxygen concentrator?

Is it true the other ozone generators make toxic nitrogen gasses if hooked up to a concentrator? That one must use medical oxygen tank with them?

Can anyone clarify?

Thanks Dan


Dear Dan,

Not true.

First of all, air is composed of nearly 80% nitrogen and about 20% oxygen. There are trace amounts of carbon dioxide and inert gases, but we can ignore them for this discussion.

In simplest terms, an oxygen concentrator takes air and compresses it into cylinders filled with zeolite, a very fine powder. The zeolite has the ability to pass oxygen and hold back nitrogen. The oxygen passes on to a holding cylinder in the concentrator, from which it is metered out by a flow meter.

Most oxygen concentrators will produce just 95% oxygen. The other gas in the equation is going to be nitrogen. Therefore, all concentrators allow SOME nitrogen into their oxygen outflow.

Corona discharge ozone generators (also called 'cold spark' or 'cold corona' ) use mostly current to produce ozone from oxygen. If the feed gas coming into a corona discharge ozone generator has nitrogen AND is moist, then harmful nitrogen compounds will be created, mostly nitric oxide.

If the air is NOT moist, then there will be no production of nitric oxide.

The feed gas to a corona discharge ozone generator can be made dry by using an air drier, or by HEATING it. One of the things that happens when you compress air is that it is heated. As it is heated, its relative humidity drops. Therefore, oxygen being produced from an oxygen concentrator and supplied to a corona discharge ozone generator will NOT produce much nitric oxide, and is therefore safe.

Air dryers are used around the world to reduce the humidity of air supplied to industrial corona discharge ozone generators, and allow it to be used without more expensive separation of oxygen.

A cold plasma ozone generator will not produce nitric oxide, even when used with air as feed gas, because it uses virtually no current. So using an oxygen concentrator with a cold plasma ozone generator is never a problem, either.

Regardless of ozone generator type being used, the feed gas from an oxygen concentrator cannot be used for intravenous injection of ozone, because of the nitrogen content.
