  • Hi,

    I have an Airsep Freestyle concentrator for sale. It comes with a fully working battery pack, the AC power lead, battery charger, its own pouch for carrying it in and the shoulder strap. We have just had it fully serviced by intermedical which gives it a years warranty, but unfortunately the slight heftier price. Previous to this it had very little use. The unfortunate reason for selling is due to a family member death. The machine was brilliant, and unbelievably useful for increasing mobility.

    The machine has three pulse settings, and the inbuilt battery is very useful for when you need to change power sources. A link to the detailed specs of the machine can be found below.


    Feel free to drop me a message if you would like to come and look, am based in Cambs.

  • Is the Activox still available?

  • Hiya,

    We have a SeQual eQuinox Model 4000 (with autoSAT) that we would love to go to someone who can use it. Includes owner's manual, a trolley, padded carry bag that attatches to the trolley, mains charger, standard 12 Cell battery, and a second upgraded 24 Cell battery (for longer battery durations).

    Gently used and looked after, the concentrator is in perfect working order and is less than a year old - purchased late 2015. There are a few minor scuffs on the back of the trolley and the larger 24 Cell battery as it sticks out a bit from the machine. Unfortunately we don't have any of the original sales paperwork or the DC cable/car charger as it belonged to a relative that has passed (they've somehow gone walkabouts!), but the car charger can be purchased separately for about £50.

    Happy to provide photos if interested. We live in Coastal East Sussex and we're willing to arrange delivery if local, or willing to meet half way if further. Paid just under £5,000 new (with optional battery upgrade), asking £3,200.

    Please feel free to contact us for further information.

    Also advertised on local for sale sites.

  • Hello, I was wondering if your Sequel Equinox is still for sale. I am interested in buying as I have PF and have to be on oxygen 24/7. Will collect if necessary,

  • We still have this for sale - willing to let it go for £2,500.

  • Hello!

    Is the SeQual eQuinox Model 4000 still for sale please. I'm urgently needing a portable unit that can provide continuous flow for night time use when visiting my family in the UK at the end of this month.

    I look forward to hearing from you.

  • Dear friends,

    I am in desperate need to buy or rent Inogen one G2 batteries. I am unable to get spares and cannot afford new ones. If anyone can sell or rent me batteries it would be greatly appreciated. I am in North West London, but will be able to travel most places in the UK to pick up.

  • I have a Sequal Eclipse Portable oxygen concentrator for sale. It was fully serviced in 2014 and has only been used for a few hours since, plus a couple of hours every 2 months to keep the battery charged. This is an essential piece of equipment for holidays and I am looking for offers around £650.00. Can be collected and seen operating West London/Middlesex area

  • Hi is the equivalent still available for sale

  • Hi there, I have an Airsep Freestyle Portable Oxygen Concentrator for sale. Includes car charger, portable 'air belt', carry case and all the extra bits. Lots of photos available, please message me so I can email them across. Selling due to my father's illness getting the better of him earlier this year. He bought this for £2000, I'm looking for around £1200 o.n.o. Great condition, very clean, well looked after. I'm in Dorset, willing to deliver locally or post (well wrapped!) to anywhere in the UK.

  • Hi, I would like to know if anyone has a spare Inogen one G2 battery for sale. Thanks

  • Hi. Does anyone know where I might get a reasonably priced Inogen One G2 backpack? The carry bag is fine but if I don't want to carry another bag it gets a bit full with a spare battery, wallet, phone, etc etc. The G2 has now been discontinued so I'm sure there must be a few out there. I've tried eBay, Gumtree, Exchange & Mart, etc, for a second hand one. I'm really not prepared to pay over £150 for what's basically a customised rucksack!


  • rogerw117

    Just an idea if it is not too late. I bought from a sports shop a cheap (£10-12) small backpack that was just slightly larger than my machine and cut out some panels for the air inlet and outlet. It had the advantage of having a reinforced hole for ear plugs through which I could push the air tube. Works very well.

  • Cheers. I keep thinking I'll try that but worry it has to be a snug fit so that the airflow is unimpeded. I'll give it a go. Thanks

  • Mine has a bit of room on all sides but settles easilly into the middle allowing chargers etc to also fit in. Just make sure that the air panels are roughly in the right place or large enough that they cannot block the air flow. My machine is an Inogen G2 where the in and out are on either side of it. May be a bit more difficult if they are on the front, back or top. Good luck.

    My only problem is that I think the backpack was for a child and I have had to find a way to put it on which saved me having to lengthen the straps. A bit of a fiddle but if I get fed up a sailors palm will do the job.

  • I have a G2 too. What I'm trying to do is avoid having two bags. The problem I'd have thought with a standard backpack is that you put other stuff in (bits of shopping, etc) then if you need to change battery you have to unpack and repack. The Inogen backpack (see ) appears to be in two compartments, which would be ideal. I can't believe there aren't second hand ones out there, what with (a) the G2 being discontinued now and (b) the natural, er, turnover of people who need oxygen. Inogen's own prices, for anything, and unbelievable.

  • Roger,

    I could take photos of my rucksack to show you how much room there is. I think most student ones have to have a large enough space for medium/large laptops which are much longer than the Inogen, so mine has quite a bit of space above the Inogen. It just depends on how much shopping you are going to do. Having seen the Inogen bag, once you have a cannula and another battery in there I doubt there is any room for shopping unless it is a bar of chocolate !

    Another alternative would be pulling a trolley with a shopping bag on it, or one of those in plane bags on wheels.



  • INOGEN ONE G3 portable concentrator for sale with Carry bag, all charge equipment, user manual and longer life battery. I bought this for my wife in March 2016 and it was used for 1 month. Since it has been kept in my study. I would really like to see it go to a good home to help someone else in need. Asking price £1850 for a quick sale.

  • Hi is this still available

  • Hi

    I have a Philips EverGo POC (Portable Oxygen converter) for sale at £1200. It originally cost £3000 and has barely even been used. It comes with a fully working battery pack. the AC power lead, battery charger and as it is also on wheels it can be pulled along or used with the shoulder/hand strap. This gave my father a great deal of peace of mind as he did not need to worry if he ran out of oxygen cylinders as he always had this as a backup for 'just in case'. Perfect for travel as it is so compact and acceptable for use on airlines.

  • I have an AirSep Freestyle portable oxygen concentrator and AirSep Freestyle Airbelt for sale. My sister in law bought it in 2009 for £2870 and only used it for 2 months before, sadly, passing away. It has been lying in a cupboard since. Intermedical, the company she bought it from, will give it a free service and post it free to anybody who buys it . I have been told by the technician at Intermedical that it will probably need a new battery which Intermedical sale for £295. The AirSep Freestyle Airbelt is in perfect working order and is worth £440 alone. I am looking for £200 for everything as it is just sitting in my cupboard gathering dust.

    It come complete with the original receipt and documents from Intermedical.
