    I was thinking that this specific booster might be just what I'm looking for, does anyone have any experience with it or know where I can find one? The Haskel reps I've emailed said it is not in their system as available any longer. I would like to use it to scavenge Nitrox from cylinders after diving and before returning for fills. I would also use it to scavenge O2 from deco bottles before filling for the same reason (but at this point don't know if O2 is sold by the fill or cu ft).

    I know this will never be economical, but I miss my fill station and like to tinker in the shop!

    you don't want to do that with a hand driven booster... It will take forever and be quite exhausting. Get a pneumatic one

    What you could consider is a small multi stage (3 stage) industrial gas scavenging pump (Not a booster) a small compressor like device used to evacuate expensive gas from storage size cylinders for re use, re storage or resale while the empty cylinder is either retested inspected or re assigned with another gas.

    Although they are capable of scavenging down to zero pressure for practical time constraints 20 psi is the common cut off point to consider the doner cylinder empty. Flow rate is around 6 litres per minute regardless of imput pressure down to 25 psi before the flow rate drops off. The maximum discharge pressure is around 155 barg 2200 psi for when you are scavenging pure oxygen or high oxygen concentrations.

    In industry some gases are also extremely rare or expensive to produce it is these that are normally hooked up to a scavenging pump. The 6 LPM flow rate would require around 30 minutes to migrate the contents of a 3 litre scuba size cylinder at 50 bar 725 psi down to 20 psi. Power is single phase 110v 60hz or 240 volt 50hz block and uses a small half horsepower (0.5 BHP) motor. A 3 stage unit. Fully automatic with auto stop and fully protected with safety valves each stage Cost new is around £3,500 sterling $5,500 USD

    @iain/hsm so when can we get someone to make said 3-stage, O2 clean compressor that is good for more than 2000psi out of the box? 2200 is not quite useless, but it's useful for the first stage of compressing, still needs a 4th stage to make it useful for this application.
    The microboost isn't the ideal solution for this though since the haskels let you equalize through the booster. Doesn't the microboost need the inlet gas regulated to quite a low pressure so you don't it up? I want a microboost, but not for this application, and not until it has at least a 3000psi rating to deal with the high pressure medical O2 bottles and be useful for scuba tanks

    @iain/hsm is that the new one that they still haven't released anything for? The original microboost literature said inlet pressure of 3-25psi which means everything has to be regulated back down before being recompressed again. Hardly the most efficient way to make 1000psi gas into 2000psi gas. Either way, 2200 psi is not a useful gas pressure in scuba diving, so it's a wicked expensive investment to have to top every bottle off again.

    An easy and hard answer at the same time.

    1. An 02 clean compressor good for more than 2000psi out of the box. Three or four stage No problem
    2-4 weeks delivery for a small block longer for say a larger 10 to 30 cfm block.

    2. An 02 clean compressor (cleaned for oxygen service) good for more than 2000psi out of the box.
    Not in my lifetime ever.

    Equilization? no problem
    Both the above are capble of automatic bypass equalization filling (its simply a custom build option)

    Variable inlet Pressure? no problem
    Both the above are capble of variable inlet pressure filling (its simply another custom build option)

    All are just as happy mechanically at 3000 psi and done that many times on test loads, except for the certification, product liability and insurance considerations. All you have to do is explain to the legal guys and liability insurance providers why a 30% increase in pressure is not an additional increase in liability risk and why one small pump costing less than $5,000 could cost a multi million dollar law suit when some diver out of Florida is left wondering why his underpants caught fire and burnt his backside off running it in the bathroom
    with the shower head on to cool his tanks down while making a cave fill.

    Then we may have some progress.

    @iain/hsm philips makes one for the medical realm, not industrial compressor, but for at-home medical....

    You sure your not talking about a Philips oxygen concentrator? and if you are:

    Yes sure if your some old dude breathing your last in the corner. Hope dies last.
    But for the rest of us still breathing as divers a unit barely capable of 93% purity I would pass.

    Now you can get proper 99% purity hospital medical units made by an outfit in the UK at 10LPM dont get me wrong but plugged in for 200 barg they are around 10K made in UK and not made in China.

    On the other hand Phillips do make a nice moisture protected hair staightener with Ionic conditioning in white/rose gold a snap at $100

    https://www.amazon.co.uk/Philips-Mo...lips+hair+straighteners&qid=1578061133&sr=8-5

    Goes well at the beauty salons where you can also take a toke at the Phillips oxygen bar ROFL

    Edit: Heck its gone up £100 now.

    @iain/hsm it's called a Philips Ultrafill. It's basically an electric haskel booster that the concentrators plug into.
    I am using an Invacare homefill which is a 3-stage compressor that gets me to 2000psi and I use that for blending nitrox and for open circuit deco gases. I have a few buddies using the ultrafill's in remote locations for rebreather bottles
