    After a closer look they have range of pressure switches:


    • 85PSI/105PSI
    • 90PSI/120PSI
    • 110PSI/145PSI
    • 165PSI/200PSI
    • Ideal would be to fit 2, 1 low and one high pressure. Just add a bypass switch across the low one if you need higher pressure.

    So far in this discussion there is no mention of alternative suppliers so I'm not sure if you're all aware that there is an AOB commerce site.

    I have been looking into it and it seems to me that the smallest (4 litre) tank would meet most 4WDers' requirements and it would conveniently fit in one of the RFSV side baskets.

    I haven't checked the prices but I mention the AOB site here for the purpose of "comparison shopping"

    Similar system is a very similar price. Compressors duty cycle is the same too. Probably all come out of the same factory in China.

    They are in Melbourne though so I could go check the stuff out in person next time Im over that way. 👍

    Looks the same as the Air On Board systems.
    AOB slightly cheaper, I like their mounting systems too(for their 9lt tank), where you have the option to mount the compressor to the tank, and tank mounted to... (whatever) .. otherwise separate them if that's better.

    Also, AOB is just up the road from you Nick, up in Research, main road out to Kangaroo Ground on the left just before the paddocks(maybe 10-15mins drive).

    I've been eyeing off their 9lt tank kit with manifold for a while now.
    Slightly cheaper, but also comes with the wiring kit needed to complete it(no coiled air accessory line tho). Only extra I'd go for is the manifold they also have.

    Sorry don't have their exact address, but it'll be on their website.
    Cheers,

    Near mum and dads then, i will need to remote mount the tank i think but worth a look since they are just down the road.
    I do have a TJM Ox (thomas ) compressor so i could just get a tank but its a little slow and over heats quickly.

    Checked the address and they are in the small industrial estate just before Eltham College.

    Yeah, that's them.
    I can't remember seeing any obvious signs, but that was a while back now.

    Yeah, get a tank, whatever other bits you need etc.

    Brother's D2 TD5 came with a ARB compressor fitted(for the diff locks), and on a trip to the VHC, I was having a few tyre issues.
    Was (supposedly) easier to pop his bonnet and use his fitted compressor .... rather than using my 17 yo cheapo Chinese compressor, unpacking it, pulling out it's gear, connect it via alligator clips to battery .. etc.
    Problem was that the ARB was overheating and only allowing about 10sec of operation, maybe every minute or so.
    They'd installed it where some folks add a secondary aux battery against firewall, near turbo(heatshield still on), and I reckon turbo was 'overheating it' so it started off hot .. no chance for it to run for a few minutes from cold.

    Anyhow, due to it overheating, I unpacked half my gear, dug out the little ever reliable Chinese pump, and just took a few minutes longer to add air to my two leaking tyres!
    Left it on the passengers floor for the rest of the trip.


    So is the Ox 'installed'(like bros ARB in his D2) or a mobile setup(like me in it's bag with all it's fittings and stuff).
    if installed, maybe re think it's location.

    Like I said, I've been thinking about an AoB setup, small tank, manifold for the various stuff(added fittings, gauge, etc) but I've never had it overheat and shut down on me .. ever.
    Got it in 2002(for my Rodeo ute), not used in anger like many folks sometimes do, but used a fair bit.
    Takes for ever to inflate 4 x 225-255 sized 16's from 15 to about 30 or so PSIs, sometimes I give up, and just get up to the high 20's and find a servo down the road or something .. I'd estimate a minimum of 10 mins.
    Makes no difference high up in the mountains at 0C or out in SA deserts at 40+C .. it never fails(or more accurately never failed).
    Dinky coiled hose got chucked fairly soon, and I got a slightly better hose .. and then got another better one a few months back again.
    So part of my reasoning for not yet going with the AoB(yet) has been that the little cheapo(about $120-ish back in 2002) has worked all this time.

    The tank tho is something I'm more interested in too. Having that reserve to help fill the tyres a little quicker is more about what I'm after.
    Cheers,
    Arthur.

    The Ox is portable, i picked it up off gumtree brand new for $20 but it was bare so i made up the rest of the kit.
    I could just add a tank and bits which would help with airing up time.

    an air tank system is one of those nice to haves but has its practical limitations. First, to inflate 4 tyres you need a tank far larger than you can sensibly fit in a 4wd. After half a tyre you are relying solely on the compressor. Secondly, a decent compressor with a good duty cycle is $$ or you compromise with a small capacity compressor that takes morning tea to air up. Other than a reservoir to hold air for a lockers (that don't need much air or pressure) a tank isn't much use once its short contribution comes to an end. If you are setting up an air bag system, that is different and i'd point you to AccuAir ENDO Tanks - AccuAir Suspension that has the compressor, solenoid and valving all in the tank.

    While i generally dislike ARB. Their twin motor compressor is the best thing in their catalogue. switches between the 2 compressors to maintain 100% duty cycle. It's quick enough and compact compared to the range of Chinese made compressors (no criticism of the chinese versions, i have one and its still going strong after 10 years). I fitted my ARB twin motor under the drivers seat of the defender after moving the fuses and relays to a Mulgo box. Only criticism is the fright when the compressor kicks in under your bum and not expecting it.

    ....
    That accuair setup would be nice .. but at that price .. (it's not that nice! )
    AoB also have a tank/comp product .. far cheaper than accuair. Granted totally different products, but just pointing out that options exist.
    My mechanic used to have a small tank a generation or so ago. Can't remember the compressor he had, but the short fat tank he had must have been min 6lt, maybe 9lt .. (can't remember specifics from 20 years ago).
    But he used to run air tools, rattle gun, drill, etc.
    In the days before usable battery tools were readily available.
    He'd whip off two wheels with the rattle gun, before the tank depleted, and a couple mins to refill the tank. In about 5mins he'd have all wheels off his old Patrol shortie(from memory 6 stud, so 24 wheel nuts undone).

    For me, I reckon a 6lt tank would be ideal(for my purposes). Don't need 'endless air' .. just a good hard burst for a couple mins is fine.
    Never used the ARB twin pot, so can't comment on usability, but the price is a little on the high side for me(and others I assume).
    I'm personally not interested in inflating 4 tyres from 15psi to road psi in record time.
    Air tools are a thing of the past, too bulky and tedious to carry, suspect to dust, etc.

    So, for the purpose of inflating a mattress in quick time on the odd occasion, dusting down the rear of the disco after a days worth of dust ... or whatever other flexibility an air tank offers .. value for money, I still think the tank has the advantage.
    If you need 100% duty cycle, then of course, the twin pot ARB would be better.
    Cheers,
    Arthur.

    The aob look to be a good value system, any tank is better than no tank and combined with their 200psi 100% duty cycle would be ideal.
    I agree the 6ltr tank is enough yet still compact.
