  • 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.

  • How big is the imogen.

    Where in scotland are you?


    I have a inogen one G2 system (24 cell battery) portable concentrator for sale. Its just under a year old. Goes up to 6 LPM pulse flow. if used on 2 LMP you get 7 hours oxygen supply. If used on 5 LPM you get 4 hours oxygen supply.

    It comes with carry bag, hand strap, shoulder strap, trolley, car charger and mains charger. I also adapted a small ruck sack (black) to use with it.

    my condition has worsened over the last 4 months, and now on 10 LPM at rest and 12 LPM at movement, so sadly the concentrator is no good to me any more. Its an excellent machine which gave me so much independence and kept me out and about every where.

    When connected to car charger or wall socket, it charges it and you can use it at the same time, with out using your battery supply.

    On 24 February 2015 I bought the concentrator from intermedicial for £2995. I would accept £1400 ono. It has only been used for 8 months!!!

    It comes in original box with instruction and leaflets. I will also include original invoice, as with EEC laws, purchases are covered for 2 Years now.

    I live in West London it can be picked up or couriered which ever preferred. If your interested please PM me and I will contact you, asap.

    This unit needs a service as it has been sitting in a cupboard for a couple of years. Intermedical do these for the price of £150.00. Rang them to check pricing.

    This has had very little use and is in pristine condition.

    The reason for sale is due to my mother just not using this machine. Brought at a price of £3000.00 in 2010.

    Price £1,300

  • LifeChoice ActivOx 4L with additional external battery pack for sale. As new, used only for 2 weeks. £1200 or offer


    I'm new here, and don't know that much about the equipment I'm afraid. My father had pulmonary fibrosis and sadly died in January. He had very recently bought himself a new POC. I don't want to sell it to a company who will profit from this; I would much rather it go to someone who really needs the equiment and can benefit from it.

    It is an ActivOx4L, with additional external battery pack, and all the mains and car chargers etc. I can't find the carry bag for some reason, and so it is without that at the moment.

    My Dad purchased the machine on 30 November 2015, and used it for 2 weeks only, so it is still as new, under warranty and with all paperwork.

    My Dad paid £2500 for it. I've suggested £1200 but am very open to offers, and I will be giving half of the proceeds to charity.

    Please feel free to ask me any questions and I will do my best to answer them.

    I very much hope that someone else can benefit from this machine in the way we hoped my Dad would have done for longer.


  • Hi costacal

    Sorry for the late reply - I didn't see your response until today. It is still for sale. I am based in Edinburgh, but am happy to either send by post or courier, or it can be delivered to my brother who lives in Buckinghamshire.

    The unit was new in November 2015 and was used by my father for 3 weeks only, so is still under warranty etc, and as good as new.

    Please let me know if this is of any use to you, or if you have any other questions about the unit.

    Many thanks.

    Kind regards,

    L-J Stewart

  • Hi Ian

  • 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 charger can be purchased separately.

    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 £3200 ono.

    Please feel free to contact us for further information.

    Also advertised on local for sale sites.

  • 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.

  • 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!

    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.

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.
