Portable Oxygen Concentrators for Sale
Stationary Oxygen Concentrators for Sale
If you've been prescribed oxygen therapy for COPD, emphysema, pulmonary fibrosis or another chronic respiratory condition, your prescription has already made most of this decision for you.
What's left to work out is where you'll be using the machine.
A stationary concentrator is the standard choice for home oxygen therapy:
A portable oxygen concentrator is built for leaving the house:
The two work together rather than competing. If you need oxygen both at home and when you're out, a stationary machine covers resting and overnight hours while a portable covers appointments, shopping and travel.
Check the delivery type before you pair them. Most portables are pulse dose only, so if your prescription is written in litres per minute, you'll need one of the continuous flow models.
Pulse dose means you receive a measured burst of oxygen each time you breathe in. The machine senses your breath and releases a set volume, measured in millilitres per minute.
Continuous flow means a steady, uninterrupted stream, measured in litres per minute (LPM). Your prescription will be written in one or the other, and the two aren't interchangeable.
Pulse settings also aren't standardised. A setting of 3 on one brand won't deliver the same amount of oxygen as a setting of 3 on another, because each manufacturer decides how much its own settings release.
The fairer comparison is bolus size, the millilitres per minute a machine actually puts out. We've listed it below where it applies. The Zen-O and Eclipse 5 are rated in litres per minute instead, as both also run continuous flow.
If your prescription is written in litres per minute, you'll need either a continuous flow machine or an assessment with your prescribing practitioner to work out which pulse setting matches it.

Noise isn't a deciding factor here, as every unit sits between 37 and 43 dB(A) at setting 2. If your oxygen requirement rises during exertion or pulmonary rehabilitation, look at the two continuous flow models.
| Model | Flow | Purity | Weight | Noise | In the box | Warranty |
|---|---|---|---|---|---|---|
| Yuwell Stationary Oxygen Concentrator, Ultra Silence | 0–5 LPM continuous | Above 90% at 5 LPM | 15.5 kg | Under 42 dB at 10 cm | Humidifier and adapter tubing, caster wheels | 3 yrs or 9,000 hrs |
| Yuwell Stationary Oxygen Concentrator, 5L | 0–5 LPM continuous | 87–95.5% | 16.5 kg | 48 dB at 1 m | Humidifier and adapter tubing | 3 yrs or 9,000 hrs |
| VisionAire 5 Oxygen Concentrator | 1–5 LPM continuous | 90% (+5.5/−3) | 13.6 kg | 39.5 dB(A) at 3 LPM | Unit and manual, no scheduled maintenance | 3 yrs |

Three of these are 5 LPM machines built for the home and three are 10 LPM machines for higher-flow use. The 10 LPM units are heavier, louder and draw roughly twice the power.
Both NewLife Intensity units put out 20 psig, more than double a typical high-flow concentrator, which lets them run tubing out to 61 metres and drive high-pressure applications. The dual flow version splits its 10 LPM across two outlets, so two patients can run from the one machine.
Have your prescription in front of you and check:
Oxygen is a prescribed medical treatment. We ask for a copy of the prescription before dispatching certain devices, and none of these machines is intended for life support.
If you're not certain which model suits your therapy, call us on 1300 881 824 before you order rather than after.
Spare batteries, carry bags, filters, cannulas and tubing are in Oxygen Concentrator Accessories & Parts.
Yes. Every stationary unit on this page is sold for home oxygen therapy and ships Australia-wide, and they suit patients on long-term oxygen therapy for COPD, emphysema and similar respiratory conditions.
Oxygen is a prescribed treatment, so your doctor sets the flow rate and delivery type. We ask for a copy of the prescription before dispatching certain devices.
Concentrators are sold as medical devices in Australia, and we don't dispatch every model without a prescription on file.
Buying one without a clinical assessment also means guessing at your flow rate, and too much oxygen and too little are both dangerous. A pulse dose device in particular needs testing by your medical practitioner to confirm it delivers what you need at your breathing rate.
Match the delivery type and output to your prescription first, which usually leaves two or three candidates. From there, compare:
Compare bolus size in millilitres per minute rather than setting numbers, as the numbers aren't standardised between brands.
Then compare battery hours at the setting you'll actually be using. The Freestyle Comfort's 16-cell pack gives you 8 hours at setting 2 but 4 hours at setting 5, and every machine in this range drops off the same way.
Stationary machines are the cheaper option, and 5 LPM home units cost roughly half what a 10 LPM machine does. Portable concentrators cost more again, with continuous flow models sitting at the top of the range.
Current pricing for every model is shown in the product grid above. Hire and rent-to-buy options are available if you'd rather spread the cost or trial a machine first.
Yes. We hire both portable and stationary concentrators, which suits short trips, recovery after surgery, and trialling a model before you buy.
Our rent-to-buy option puts your hire payments toward the purchase price if you decide to keep the machine.
Medicare doesn't fund portable oxygen concentrators. Some state-based home oxygen schemes subsidise stationary equipment for patients who meet the clinical criteria, and DVA and NDIS funding applies in some cases.
Eligibility differs between states and programs, so check with your prescribing clinician before assuming either way.
All six portable units on this page are FAA approved, though approval alone doesn't oblige an airline to let the device on board. Before you fly:
The Yuwell units use a compressor rated beyond 30,000 hours and carry a three-year or 9,000-hour warranty, whichever comes first. Most machines here are warranted for three years.
How long yours lasts comes down to run hours, filter care and servicing. We service and repair oxygen equipment in-house if something does go wrong.
