What to look for when buying an industrial oxygen tank?

New or used? Always buy a new tank. When you buy a new tank, you know it has been properly inspected, there are no impurities and it has not been handled inappropriately. Put a sticker on it or mark it in some way and when you get it filled at your local welding shop, make sure you get the same tank back. This is how you maintain a chain of custody.

Capacity: How much oxygen do you need? How long do you want it to last? As long as possible, right? But of course the bigger the tank, the larger and heavier it is. So be prepared to compromise. Most industrial tanks are made of steel which makes them heavier than aluminum tanks.

A 20 CF (ca. 566 L) tank will last you several months to a year. Even if you will empty it quicker: no problem. Oxygen is cheap. You can get it refilled for around $20. No prescription needed.

If you were to do only rectal insufflations, you would be able to do over 1,000 if you insufflated 500 ml each time. This is more than 3 years worth of daily insufflations.

Example: If you do per week 3 RI, 2 VI, and ozonate water twice a week, and do one ozone sauna per week, you will use per week around 21 L, in which case a 566 L tank will last for around 7 months.

Will you need a prescription to get a medical oxygen tank filled? No. Industrial oxygen tanks do not require a prescription. Find a local welding or gas shop which will fill your tank. Make sure they will give you the same tank back. Do not swap tanks. Be prepared to have to wait a few days for the refill.

Is an industrial tank good for all ozone applications including IV and other injections? No. Or at least I wouldn’t do it. I would use industrial oxygen only for insufflations, saunas, make ozonated olive oil, ozonated water. But not for IVs or other injections.

It is a good idea to use an inline filter with any tank, but especially with an industrial tank. Keep things as pure as possible.

If you opened an oxygen tank without a regulator attached to it, the oxygen would soon escape within a very short time. A regulator makes sure that that the oxygen flows out at a controlled speed and that it lasts for a long time.
Every tank requires a matching regulator. An industrial tank has a CGA 540 valve which calls for a CGA 540 regulator. Ozone therapy with home ozone generators calls for very low flows of oxygen down to sometimes 1/32 LPM. This is the reason why only low flow pediatric regulators are used.
Pediatric regulators typically have the following flows: 1/32, 1/16, 1/8, 1/4, 1/2, 3/4, 1, 2, 3, 4 LPM. During home ozone applications you will only need very low flows, like the ones marked in bold.
Above I have only listed the most precise regulators. You will likely find more affordable models. I have only listed the models I can recommend. Cheaper models have turned out to be more unreliable and to not produce the flows they should. The flow of low quality regulators can vary by up to 50%. Since with home ozone generators the ozone output depends largely on the flow of oxygen, this can lead to a great difference in ozone concentration. Better spend $30 more on a regulator and have the security that you are getting the oxygen flow you want.
Promolife‘s and ozonatedoilonline‘s regulators seem to be the most precise ones.
Barb or DISS outlet? A barb outlet allows silicone tubing to be slipped on easily. A DISS outlet requires an additional Christmas tree type adapter. Diss the DISS, choose a regulator with a barb outlet.


barb vs diss outlet oxygen regulator

An oxygen regulator can come with a DISS or a barb outlet. Barb outlets are more practical. You can slip on a silicone tubing directly onto them. A DISS outlet would require an additional Christmas type adapter.


When you hold an oxygen tank at home, you hold an object under high pressure. Mishandling could lead to the cylinder turning into a missile and cause damage to humans and property. It is therefore of utmost importance that you secure your oxygen tank. Either keep it in a cart or bolt it to a wall. Keep it away from heat sources, open fire, and children.
