O2Ready XL extra large prefilled oxygen tanks are a great choice if you need high purity oxygen delivered to your door for use with your ozone generator.

O2Ready XL oxygen tanks come filled with 99.9% pure oxygen. This purity level is higher than even medical tanks and is the perfect choice for those who need high purity oxygen for ozone equipment. There is no need for a prescription or refills. These tanks use a standard CGA 540 (industrial) regulator which can be reused from tank to tank. If you don't already have a regulator, you can add one to your order above.

Shipping note: Due to shipping restrictions, these tanks can only be shipped to the contiguous USA or Canada by Ground. Expedited options are not available. If priority or priority express is chosen during checkout, we can still only ship these tanks via standard Ground.

How long do they last?

O2Ready XL tanks hold 600 liters of oxygen. For moderate daily use with your ozone generator, one tank will last about three to four months. For light users each tank will last up to six months. It depends on your usage of course, but below you can see some examples to determine how much you might use.

Examples (applications)

  • Making ozonated water at 1/16 LPM takes 15 minutes. This will use about one liter of oxygen. This means you could ozonate water up to 600 times per tank.

Examples (continuous flow)

  • With a flow rate of 1/8 LPM you can get about 4800 minutes or 80 hours of continuous use.
  • With a flow rate of 1/16 LPM you can about 9600 minutes or 160 hours of continuous use.

How do I know this is right for me?

O2Ready XL Oxygen Tanks are ideal if you can't get a medical tank, don't have a local source of industrial oxygen, don't want to deal with getting tanks refilled, or need higher purity than an oxygen concentrator can provide. They are also perfect if you just like the convenience of having your oxygen delivered right to you for use with your ozone generator.

You might not want them if you plan to run oxygen continuously or for extended periods of time. Depending on your area, medical or industrial tanks might be more economical in the long run because they can be refilled.

Due to their size, we can not offer the store credit empty tank returns that we do on the smaller O2Ready tanks.

How to purchase

O2Ready XL Tanks can be purchased in any quantity. Choose the number above. If you’ve purchased some in the past and already have a regulator, you will not need another. If this is your first purchase and you do not have a CGA 540 low flow oxygen tank regulator you will need to add on a regulator above in order to use your tanks.

Securing your Tank

Due to the size of these oxygen tanks we recommend purchasing an oxygen tank holder/stand or strapping the tank down before using. Storing the tank properly will ensure the tank does not fall over during use. Straps are included with the tank to assist in securing the tank before using.
