Cylinder Storage, Backup Supply and Power for a Home Setup
A home oxygen concentrator is a mains-powered appliance that separates oxygen from room air, and the parts and accessories around it exist mostly to cover the situations where the concentrator alone is not enough. This collection carries cylinder racks and carts from Drive Medical, OxLife power supplies and batteries from O2 Concepts, and a transfill rack from Rhythm Healthcare.
The defining fact about a home concentrator is that it needs electricity. It produces oxygen continuously and indefinitely while the power is on, and nothing while it is off. That single dependency is why backup cylinders are part of a home oxygen setup rather than an optional extra, and why the storage equipment in this collection matters as much as the concentrator does.

Backup Cylinders: Why Every Home Setup Needs Them
A power cut stops a concentrator immediately, and for someone on continuous oxygen that is not an inconvenience. Cylinders hold a fixed quantity of compressed oxygen and work without electricity, which is exactly the property the concentrator lacks.
How much backup to keep is a question for the prescribing clinician and the oxygen supplier, since it depends on the flow rate, how long the person can manage without supplemental oxygen, and how quickly power is typically restored in that area. What is not in question is that some backup should exist, stored where it can be reached in the dark.
That last point is worth stating plainly. A power cut means no lights. Backup cylinders stored somewhere that requires navigating stairs or a cluttered room in darkness are backup cylinders that create a fall risk at the moment the person is also short of oxygen.
Storage racks by cylinder size
Cylinder designations describe size and therefore how long a cylinder lasts at a given flow. Racks are built for specific diameters, so a cylinder sitting loose in an oversized rack is not actually secured.
- For D or E cylinders: the Drive 18111 chrome rack for 6 cylinders and the 18112 for 12 cylinders.
- For M6 cylinders: the 18113 for 12 cylinders.
- For larger stationary cylinders: the 18149KD metal stand for M60, M90, MM, H and T.
- For higher-volume storage: the 18141 chrome rack for 28 cylinders.
Why securing cylinders is not optional
A compressed gas cylinder stores considerable energy. One that falls and shears its valve becomes a projectile, which is why cylinders are secured upright rather than leaned in a corner or laid on a floor.
There is a second hazard that matters specifically in a home. Oxygen is an oxidiser: it does not burn itself but makes everything else burn far more readily, and materials that merely smoulder in normal air ignite readily in an oxygen-enriched atmosphere. That is why oxygen storage requires separation from heat sources, open flames and anything oily or greasy, and why smoking near oxygen equipment is a serious hazard rather than a rule of etiquette. Your oxygen supplier and fire service will have specific guidance for the home.
Moving cylinders
The Drive 18143 chrome cylinder cart for 12 cylinders. Carrying cylinders by hand is both a manual handling risk and the situation in which they get dropped, which is the event the securing requirement exists to prevent.
Transfill: Filling Your Own Portables
The Rhythm Healthcare LM5BA9 transfill rack for the LM5BA 5L stationary concentrator allows portable cylinders to be filled at home from the stationary unit.
For a user who goes out regularly, that changes the logistics of oxygen therapy substantially. Without transfill, portable supply depends on delivery schedules: the user has to plan outings around what is in stock, order ahead, and be at home when the delivery arrives. With transfill, portable cylinders are a resource the household produces rather than waits for.
The practical constraint is that filling takes time and the stationary concentrator is doing that job rather than supplying the user during the fill, depending on the system. Transfill also has to be operated according to the manufacturer's instructions, since it involves compressing oxygen into a cylinder rather than simply routing flow.
OxLife Power Supplies and Batteries
The O2 Concepts OxLife Independence bridges home and portable use, running from mains at home and from battery or vehicle power away from it, which is why its power components appear in a home parts collection.
For the Independence: the AC power supply for home use, the DC power cord for vehicle use, the replacement battery, a protective cover and a pull handle kit.
For the Liberty2: the AC power supply and the DC power cord. Also a rechargeable battery for OxLife.
Why a spare power supply is worth having
A power supply is a consumable in practice rather than a permanent part: cords flex, connectors wear, and a unit that lives on the floor gets stepped on and rolled over. For someone dependent on the device, a failed power supply is an urgent problem, and waiting for a replacement to arrive is not a comfortable position.
A DC cord serves a related purpose. It lets the device run from a vehicle, which covers both journeys and the scenario of using a car as a power source during an extended outage, subject to the manufacturer's guidance on vehicle power.
Batteries lose capacity over their service life, so a replacement battery is a maintenance item rather than a spare. A battery that comfortably covered a routine outing when the device was new may not cover it two years later, and that decline is gradual enough to go unnoticed until it matters.
Frequently Asked Questions
Why does a home oxygen setup need backup cylinders?
Because a concentrator needs electricity and stops immediately when the power does. It produces oxygen continuously while running and nothing while off. Cylinders hold a fixed quantity of compressed oxygen and work without power, which is exactly the property the concentrator lacks. How much backup to keep depends on flow rate and circumstances, and should be set with the prescribing clinician and oxygen supplier.
Where should backup cylinders be stored?
Somewhere reachable in the dark, secured upright, and separated from heat sources and flammables. A power cut means no lights, so cylinders stored up a flight of stairs or across a cluttered room create a fall risk at the moment the person is also short of oxygen. The storage position should be chosen for the circumstances it will actually be used in.
Why must oxygen cylinders be secured upright?
A compressed gas cylinder stores considerable energy, and one that falls and shears its valve becomes a projectile. Securing upright in a rack or stand prevents that. Racks are built for specific cylinder diameters, so a cylinder sitting loose in an oversized rack is not actually secured even though it looks like it is.
Why is smoking near oxygen equipment so dangerous?
Oxygen is an oxidiser: it does not burn itself but makes everything else burn far more readily, and materials that merely smoulder in normal air ignite readily in an oxygen-enriched atmosphere. That applies to clothing, bedding, hair and furnishings around an oxygen user. It is a serious fire hazard rather than a rule of etiquette, and oxygen suppliers and fire services provide specific home guidance.
What do D, E and M6 cylinder designations mean?
They describe cylinder size, and therefore gas capacity and how long a cylinder lasts at a given flow rate. D and E are common portable sizes, M6 is smaller, and M60, M90, H and T are larger stationary cylinders. The designation matters when buying storage, because racks are built for specific diameters rather than being universal.
What does a transfill rack do?
It allows portable cylinders to be filled at home from a stationary concentrator. Without it, portable supply depends on delivery schedules: planning outings around stock, ordering ahead, being home for deliveries. With transfill, portable cylinders become something the household produces rather than waits for, which changes the logistics of going out considerably.
Is there a downside to transfill?
Filling takes time, and depending on the system the stationary concentrator is doing that job rather than supplying the user during the fill. Transfill also has to be operated according to the manufacturer's instructions, since it compresses oxygen into a cylinder rather than simply routing flow. It is a capability to be set up properly rather than improvised.
Why keep a spare power supply?
Because a power supply is a consumable in practice: cords flex, connectors wear, and a unit living on the floor gets stepped on and rolled over. For someone dependent on the device a failed power supply is an urgent problem, and waiting for a replacement to arrive is not a comfortable position to be in.
What is a DC power cord for?
Running the device from a vehicle, which covers journeys and, subject to the manufacturer's guidance on vehicle power, the scenario of using a car as a power source during an extended outage. For a device that bridges home and portable use, having both AC and DC options means it works wherever the user is.
Do concentrator batteries need replacing?
Yes. Batteries lose capacity over their service life, so a replacement is a maintenance item rather than a spare. One that comfortably covered a routine outing when the device was new may not cover it two years later, and that decline is gradual enough to go unnoticed until it matters. Planning replacement rather than waiting for failure is the better approach.
