demonsurfer23 Posted August 23, 2009 Report Share Posted August 23, 2009 thanks i think the s16 buddy bottle is a 400cc and it takes rather a lot to fill it would fill it but it would take a lot out of the divers bottle each time i.e proberbly 4/6 fills Quote Link to comment Share on other sites More sharing options...
holly Posted August 23, 2009 Report Share Posted August 23, 2009 ive been filling my air arms 410 with a 232 bar bottle for 5 or 6 yrs used to fill my mates s16 with it also 300 bar aint needed the only differance is you will get more fills Quote Link to comment Share on other sites More sharing options...
Gareth W Posted August 23, 2009 Report Share Posted August 23, 2009 (edited) you will need a 300bar tank to fill a sweet 16 buddy bottle In my experience diving for the last 5 or so years, not many places have compressors capable of pumping to 300 bar. If your buddy bottle is 400cc you should get approx 6 fills out of a 232 which holds 2784 litres of air. A 300 holds 3600 litres.

perfect Posted August 24, 2009 Author Report Share Posted August 24, 2009 (edited) Thanks to all thats replied i need to upgrade from my 7 ltr that i use to fill the bsa ultra. i found some usefull information on a diving forum I'm in the market for a tank, idealy i would like a 300 bar 12l. My regs are scubapro r190 with a din 1st stage. Will i be able to use these regs on a 300 bar bottle without causing them any damage. I'v connected them to my 3 ltr pony with about 240 bar in and they semed ok. Are all din connections the same? i was told some are longer than others? I can get hold of a carbon fibre tank realy cheap but was told they cannot be used for diving, is this so? Is there a reason most bottles are only 232 bar and not 300, Surely a 12ltr 300 bar will hold the more air than a 15ltr 232bar cylinder and would be more managable? I know they are probaly stupid questions but please bear with me as i am a holiday diver trying to convert to some hardcore british summer diving. Cheers -------------------------------------------------------------------------------- widgetMay 16th, 2009, 11:55 AM Firstly the cylinders. Scuba 12 litre / 300 bar working pressure scuba cylinders are not mass produced. Industrial 300 BAR working pressure cylinders are, but usually in smaller sizes like 7 or max 10 litres. These cylinders will have a differant neck thread to prevent scuba valves been used. There are numerous reasons why scuba cylinders in 300 bar are not mass produced, usually its cost, inability of fill stations to fill to 300 bar etc and not ALL scuba regs can operate on a 300 bar system - but purely from a manufacturing point of view because of the above, demand is low. That said, Faber dos make them with the standard M25 x 2 scuba neck thread, but usually only on order (ie) when they have sufficient quantity for a run, this makes them relitively expensive and occassionally difficult to get hold of. No, not all Din connections are the same, 230 bar din connectors have less threads (ie) are shorter than 300 bar din connectors, the reason for this is obvious. I cant comment on the legality of using wrapped tanks in England, you would need to chat to the relevant authorities there, but here, yes, they are not allowed (illegal) in the scuba market. Certainly my suggestion is to stick to the commonly available cylinders, 12 or 15 litre cylinders in 232bar working pressure. Now the reg. I would imagine your reg has a 230 bar din as standard, so in its present format it will not fit a 300 bar scuba valve. Before you decide to buy and fit a 300 bar din fitting I would suggest you discuss the viability of using a R190 on a 300 bar cylinder with a Scuba Pro dealer.

Gareth W Posted August 25, 2009 Report Share Posted August 25, 2009 I'd get myself over to Yorkshire divers which is a wealth of information. A 15 ltr 232 bar cylinder will hold 3480 litres of air A 12 ltr 300 bar cylinder will hold 3600 litres of air. The main reason 232 bar tanks are more common are, Not many places can actually fill to 300 bar, they are ****** heavy compared to a 232. Re the reg, the thread size will be the same so you can connect it to either a 232 or 300, the difference is the length of thread, a 300 bar has more threads ie it is longer. Where in the UK are you? I have 2 x 12 ltr 232 bar in test diving cylinders for sale, I have just given up diving and all I have left to sell are those. If I was you I would just go for 232, you will be able to get it fully filled, it wont weigh as much and if you decided to go down the twins route, it will be far easier to find a second one than oppossed to trying to get another 300 bar HTH Gareth Quote Link to comment Share on other sites More sharing options...
