How big are the canisters and how heavy are they?


Canister size Dimensions
2 Litre can weight - 75g, height 15cm, diameter 5cm
15 Litre can weight - 139g, height 29cm, diameter 7cm
100 Litre bottle weight – 1296g, height 32cm, diameter 7cm

How long do the canisters last?

It depends on how deep you breathe, lung capacities vary from person to person, below is a guide for the average person:

>
Canister size Estimated breaths
2 Litre with inhaler 10-20 breaths
15 Litre with inhaler 100-200 breaths
100 Litre with mask Delivers 2 – 4 Litres per minute which is 25 to 50 minutes of constant flow oxygen

What is the largest size canister you supply?

Our cans of oxygen come in 3 different sizes: 2 Litre, 15 Litre and 100 Litre.

Can I stop and start the flow of oxygen?

Yes, our canisters are supplied with an inhaler which clips onto the top of the can, depress the inhaler cap to breathe the oxygen, loose the cap to stop. Our 100 Litre bottles are fitted with an on/off valve that gives oxygen on demand.

Can I take oxygen on board an aircraft?

Unfortunately, at present, the International Civil Aviation Organisation (ICAO) does not permit the transportation of our canisters either in the hold or in the cabin of aircraft.

How do I dispose of the empty can?

Our oxygen cans do not contain propellant as used in regular aerosols, so the empty canister can be disposed of as you would any empty can.

Are any of the bottles/canisters refillable?

No, these are disposable canisters which can be disposed of with your normal household waste collection and recycled.

My canister has arrived should it feel light and empty?

Our aerosol cans are made of lightweight aluminium and filled with 99.5% compressed oxygen and as oxygen is a gas, the container will obviously feel very light.

Is using oxygen safe?

Yes, always observe the safety rules when using oxygen, always consult your GP or health specialist before using oxygen.

How do I use the cans with inhalers or the bottles with masks?



NB. If you have difficulties opening the above PDF document, view our accessibility guide for more information.

Do the 15 Litre canisters have a regulator valve?

No, the 15 Litre can with breathing mask and tubing has a button on top you press to dispense the oxygen as you need it.

Do I need to buy the valve and mask each time?

No, once you have a valve, tube and mask, you simply re-order a 'replacement' canister.

What are the benefits of using supplemental oxygen?

Oxygen is a colourless, odourless, tasteless gas that is essential for the body to survive. The heart relies on oxygen to beat and pump blood. If there’s not enough oxygen circulating in the blood, it becomes increasingly difficult for the heart muscle to pump.

There are many benefits from taking supplemental oxygen, here are just a few:

  • Oxygen helps increase alertness and focuses concentration levels.
  • Stimulates brain activity and improves your memory function.
  • When exercising, oxygen improves endurance and recovery time it also stimulates muscle growth.
  • Oxygen helps reduce stress and anxiety, the effects of jetlag, it can also help with hangover recovery.

How much oxygen is in the atmosphere?

Today, our atmosphere contains a maximum of 21% oxygen, the rest is made up of 78% nitrogen, 0.93% argon, 0.038% carbon dioxide, and small amounts of other gases, also variable amounts of water vapour, on average around 1%. In large cities and built up urban areas the oxygen levels can be as low as 12 to 17%

“Evidence from prehistoric times indicates that the oxygen content of pristine nature was above the 21% of total volume that it is today. It has decreased in recent times due mainly to the burning of coal in the middle of the last century. Currently the oxygen content of the Earth's atmosphere dips to 19% over impacted areas, and it is down to 12 to 17% over the major cities. At these levels it is difficult for people to get sufficient oxygen to maintain bodily health: it takes a proper intake of oxygen to keep body cells and organs, and the entire immune system, functioning at full efficiency. At the levels we have reached today cancers and other degenerative diseases are likely to develop. And at 6 to 7% life can no longer be sustained.” Professor Ervin Laszlo.

Is Oxygen flammable?

Oxygen is non-flammable, however, flammable substances will ignite much more easily in the presence of concentrated oxygen and careful precautions must be taken.

  • Do NOT smoke where oxygen is being used. Any combustible material, such as alcohol, perfumes, or propane, must be kept away from oxygen containers.
  • Do NOT use oxygen around open flames, matches, cigarette lighters, candles or cigarettes.
  • Do NOT use oxygen around other sources of heat, such as gas or electric heaters or cookers.

If you are using supplemental oxygen, avoid using lotions or creams containing petroleum — the combustion of flammable products containing petroleum can also be supported by the presence of oxygen. Turn oxygen supply valves off when not in use and store the containers away from children.

How does oxygen help with sports and exercise?

Oxygen can increase energy levels and helps prevent lactic acid build up that hinders your bodies' recovery time. It also aids with muscle tissue recovery as your exercise intensity increases, carbohydrate metabolism efficiency drops off dramatically and anaerobic metabolism takes over. This is because your body can not take in and distribute oxygen quickly enough to use either fat or carbohydrate metabolism easily. In fact, carbohydrates can produce nearly 20 times more energy (in the form of ATP) per gram when metabolized in the presence of adequate oxygen than when generated in the oxygen-starved, anaerobic environment that occurs during intense efforts (sprinting).

“Extra oxygen enables you to recover more quickly from exertion. It allows someone to train and then exercise again.” - Dr. John Brewer, head of sports science at Lilleshall Human Performance Centre: Health and Fitness 1999.

“If you use oxygen for 20 minutes, muscles become loosened; headaches and stress seem to disappear. There is a renewed energy and a feeling of relaxation. I am confident oxygen works.” - Dr. Richard de Andrea Sunday Herald.

How do I recycle it?

As our containers are not pressurised with CFC gasses, only oxygen, when empty, you can dispose of the canisters as you would any other form of cans.

Can the mask and tube from the 15L with mask and tube product be used with the 100L product?

The mask can be used with the 100L product, but this requires the purchase of a regulating valve also.

Do you deliver outside Europe?

No, unfortunately, due to the nature of compressed oxygen canisters, we are unable to ship outside of this area.

What is the latest time to place my order?

Provided orders are placed before 2:00PM GMT they will be processed and despatched that day for delivery via courier within 1-2 working days.
