    Default Scuba tanks/ bulk filling etc. Desperate for advice.

    I desperately need advice on bulk filling. I can get a 10 liter tank (300Bar), but without any fittings.
    I?ll only be in Pretoria for the weekend 27-28 May and need to buy what ever else I need to fill a BAM 51 and to fill the tank if it?s empty. Where do I buy these things and where do I have the tank filled?? How many times can I fill the rifle on a full tank?
    Can I standardize to fill a CZ 200 with the same connector fittings?

    Swannie you will need to buy a adaptor for every rifle because the adapter for the BAM and the CZ differs. If you buy the dive tank you should get the tank and the valve that goes on the bottle to keep the air in and that you turn to release air to fill your gun. If it is a steel tank that you will also have to buy a boot because the bottom of the tank is round, a net and a handle. If it is a Ali you don't need to, but you get a adaptor that fits onto the tanks valve that you might have to get. I think they call it a "u" clamp, because the presure gage might be to big, that when you screw it into the tanks valve that it doesn't close tight, this "u" clamp makes a tight fit easy.

    With a 10L bottle you can fill your gun about 15 - 19 times or more depending on what presure you fill your gun too.

    Just make sure that when you buy the dive tank that it is certified as tested, because air under that kind of presure is very dangerous.

    Afaik the cz 200 tank screws directly into the dive cylinder and you fil it like that.The bam requires a filling adapter with a gauge so that you dont over fill your gun,.10L 330 Bar tank should give you 30+ fills if yiou do not shoot till the gun is empty ie keep it in the sweet spot.

    Ok, so I need differant adapters for BAM and CZ200. Are they quick fit like hosepipe fittings or do I need spanners between changings?

    As it is, I'll only be shooting at home. The tank will lie on it's side in the garage, no need to stand up. I'm the only one that needs help to stand up, sometimes heha.
    What is a K-fitting and J-fitting? and now a U-fitting?

    Hi Swannie.........

    this is basically what you need to get.

    [img][url]http://www.airgunbuyer.com/ecommerce/small/md1.jpg[/img]

    you get 2 type of fittings on the cylinder, a-clamp and din (showing). with the din fittings you get 232bar and 300bar (more threads) specs. personally i've got a steel 10l 300bar bottle complete with boot/net/handle........etc these are not necessities, but sure makes it much easier to move it around/filling/storing...etc the netting also protects the exterior from scratches...etc i suppose i don't shoot a lot.......i go for refills +/- every 6 weeks and often the tank is still sitting @ 230bar........it will give you sh!t loads of fills.

    then you need the gauge/hose/bleed connector. you can get already made ones from BAM/AA...etc just make sure it's 300bar rated (ie it will fit/seal into the 300bar fitting) or else you need to get it modified or get a custom one made up.

    at the end of the hose, that's where you fit the adaptors for different rifles. usually the adaptors are 1/8" bsp male, so you need the female on the end. alternatively you can get qc couplings for different adaptors..........much much easier. don't the CZ's comes with din adaptors that can go straight into the bottle? again check for 300bar compatibility else just get the adaptor for it to go on the end of the hose.



    don't know PTA so can't tell you where to get all the stuff.........but here in durbs, i go to this hydro testing place (the mothership where all the scuba places get their cylinders checked....etc) to get all the fittings/adaptors/fills....etc as some scuba shop don't fill to 300 bar.

    I don?t necessary want to fill to 300Bar. What do you people normally fill to, isn?t it only 230Bar?

    Just for interest, here is a link to the CZ page for the CZ 200:
    [link=hyperlink url]http://www.czub.cz/index.php?p=32&idp=4&ids=13〈=en[/link]


    And for the CZ 200's manual in PDF format (has some info on refilling):
    http://www.czub.cz/rozkresy/cz200_en.pdf#sea

    Perhaps someone should draw up a nice guide to refilling and scuba tanks and adaptors and we can stick it in this forum's article section for future reference or make a sticky thread?

    Swannie, I know of 2 scuba shops in Pretoria,but I never heard someone filling there or filled there myself sincce I do not yet own a PCP. The first place is at Menlyn Shopping centre and the ground floor next to the rugby shop (same floor as Game) and the second place is next to the N4 going into Pretoria, on Rossouw offramp turn left at robot and then directly left again(murraufield south suburb).Good luck

    Swannie, I see that most of the aspects have been covered by others, but I would like to mention that the 300 bar tanks are not the be-all and end-all of the PCP industry...... If your rifle shoots well at a lower fill value, as determined by the "sweet-spot" method, then stick to it..... I personally use an old 12 litre steel scuba tank filled to 230 bar on my BAM B-50, which I only fill to 180 bar. Thanks to Arnold's tinkering, I get up to 70 shots without POI shift for 12 ft.lb FT. With some 20 refills depending on how low you shoot the pressure and at R25 per fill of the bottle, who's counting.....!!!!! This is good enough for me.....!!!
    In the whole of the Western Cape, there are only 3 fill stations who can fill to 300 bar, and I am just worried that your rig, as explained by others, will become very expensive to handle even higher pressures....
    The part I use on the tank is from the first stage of a scuba demand valve, running a high pressure line from the high pressure side, together with a T-piece to a large-size pressure gauge and ending in the Foster fitting for the BAM fill valve. To bleed off the air, I use the low pressure side of the first stage and the same pipe normally connecting onto the buoyancy jacket of a diver's rig. This is only set to 150 psi max., which is a safe way to purge the air once the rifle is filled. The "expensive part" is the first stage valve, go and see a dive shop for parts, but don't pay more than R500..... The rest is hydraulic pipes and fittings for about R300, the gauge is R150, totalling less than R1000....
    If you need more info., please call on me...... :thumbsup

    Hi Swannie. There is a company called MSA close to the JHB market. I bought my 300 bar 6L tank from them. It came presure tested and with the valvle. There number 011 610 2600. On my CS200 I get about 30 refills.

    Thanks,

    I'm almost there.
    I made a mistake to say I'm getting a bottle without any adapters.
    What I'm getting is a bottle with its standard valve for DIN and from the pictures URABUS posted I need the part between the silver piece on the bottle and the pipe, so long as there is a female fitting on the exit to the pipe end and should be 10mm ID with a pitch of 1.0
    As a matter of fact, it could be either male or female.
    I got a price of almost R900. Isn't it a bit high?

    Swannie,
    The CZ Adaptor will not fit the pillar valve of the 300bar tank as its geometry is different to the 232bar pillar valves. My advice for what is worth is buy a tank that will be the most practical for you, I would suggest a 232bar tank as the fittings are more redily available for them. Air Arms has a good adaptor as does Henry at Twinbore (near Monticasino).
