Filling Divers Bottles

Recommended Posts

I currently have to transport my cylinder 60 miles each way to get it filled, This is a Serious pain in the Aris, The added fuel cost also puts my shots to nearly the same price as live!

 

I have seen compresors available that can Fill at 3000psi But im not sure where i stand with operating one do i need a licence or permit to fill my own airtank?

 

What would be the best choice of (model) compressor for a 14L cylinder?

I think you would be looking at some very seriouse cash to get a compressor that would be up to filling a divers bottle (£1500+) but what you can get is a little table top pump that can fill your rifle up (takes a couple of min to pump rifle up) and these start around £400 a lot of clubs use them, but they wouldnt be any good for a divers bottle, due to the amount of time they would be running for.

 

duie to the rtavelling involved it might be better idea to go for the pump option 5 mins work with the pump will be enough to get a decent charge in the rifle B) (unless your talking stealth, rapid, gladiator or BSA S10)

 

apart from anything else i would have thought a bottle that big would last a good few mopnths on pest control shooting, used ot have a 12L 232bar bottle and that would last up to 6 months and that was being used for my rifle down the club as well!

 

but if you do go for a compressor, no license or permits required to operate them in the UK (as long as its for private use only)

 

hope this helps you out

Have you not considered just buying another couple of bottles, say 12ltr @ 300bar?

That is presuming your filling station can pump that high. If not then maybe a couple of 15ltrs @232 Bar.

 

If you are dead set on getting a small compressor then the best company I can reccomend is BAUER. We use them in the Diving industry and they are some of the best available, at a price of course!.

 

3000 psi is not a problem for any decent compressor, its the c.f.m. rate that you need to look at. The higher the Cubic Feet per Minute rate, the larger the compressor(and more money).

If you are only pumping a single cylinder then this will not be an issue.

You then need to decide upon the motive power - Petrol or electric. Both of these will power a small compressor no problem. (diesel mainly used for larger units).

 

One last thing to remenber is servicing - filters, oil etc.

 

And when any compresor goes BANG......it's not a cheap day out. B)

 

No licence required for personal use.

 

Hope this may be of some help.

my local dive center (good bloke ian the owner) is as cheap if not cheaper than anywhere he does BIG 18 litre jobs just for the airgunners? 15 or 18 would make your fill trips a lot more economical

I have guessed the size as 14L but i dont know for sure

 

the info on the side of the tank is 204ATS | 211kgs/cm2 | 3000psi

The tank stands about 24" from base to top (excluding valve) the diamiter is aprox 7"

 

so 24"x7" can anyone tell or confirm it is a 14L???

what rifle are you goingot be filling? and what presure will you be filling it to?

 

reason i ask this is some rifles are filled to 200bar others are filled to 232bar (eg the BSA hornet). So if you goingot be filling it using a 232bar bottle as soon as you have had one fill from the bottle its on its way down.

 

I would have to recomend a 12Ltr 300bar bottle or if available 14+ltr

 

hope this helps you out

The gun is a Brocock Enigma Fill presure 2750psi(190bar), The tank wich i am starting to regret purchasing has just come back from the dive center and, either my Gauges are up the spout or they have not filled it correctly

 

They told me the bottle was already full , and slightly over charged to 220 bar , But my gauge indicates 100bar, Asuming my gauge was at fault i let valve full open and waited for guns internal Presure release to sound, However it didnt :<

 

It seems crazy they could have made a 120bar error ?

its possible that they didnt charge fully, when you go there make sure you tell them its for airgun use so will never be empty like a divers rig.

 

I have heard of fill centres not giving a proper blow on the bottle ;)

 

as for the filling to 220bar thats pretty common for a hot fill, due to the expansion of the air when it fills it gets pretty hot which means that at first it will register a slightly higher presure, but when it cools down a little it should level out about 200ish but no way should it drop to 120bar!!!!!

 

as for filling the enigma to 190bar shouldnt be any problems for that it might be a case of your never having had a full charge.

 

Do you have another dive centre you could fill it at? might be the best option for you as that bottle should give a good few fills before needing to be topped up.

 

a very rough guid would be a drop of about 2-5bar for each fill of the rifle, at least i think those are the figures i rember, though i would be the first to admit i could be wrong about those.

 

hope this helps you out a little

Now this takes the biscut, I have it back! and guess what it still wont charge my gun, ;) This divers bottle is a waste of space!, they found a problem with the valve but did get it pumped to the full presure 207 bar, But due to the valve problem for some reason the presure gets upto 140 bar and then it stops, like the back presure closes the valve. so am still unable to fill my gun past 140bar ;):D???

 

I paid 150 bucks for this tank and regulator , and it has cost nearly 50 quid in petrol transporting it to & from newhaven. :<

 

unfortunatly i seem to have learned the hard way about the cylinders you do and dont want for airguns, This is one definatly under Cylinders Not to get

 

I am taking it back to the shop tommorow and demanding a refund

Where are you exactly Mimic?

If you travel to Newhaven then just add a few more miles on the A27 and go into Brighton, there are plenty of divers shops there. It MIGHT be the answer.

 

(ofcourse If you filled your profile in I wouldn't have had to ask!! ??? )

If you know a place where I can you fill up in brighton that would be great? ;) , I did enquire but the ones i phoned could not fill tanks.

 

Either way im still screwed because this dam thing isnt working correctly ;)
