why cant i just take the npt female adapter and hook it directly up to a larger tank and fill my hpa tank. why do i need a regulator, bled vavle and all that other stuff. the large tanks psi is a maximum of 2600psi.

i was wondering, when you go to a scuba place to get your tank filled, do they put in compressed air like at a pro shop, or is it different? will it get dirt in the noid? i was also wondering if it were possible to get the subas filled at a local pball shop?

Diving shops often have a compressor to fill your tank, whereas pball pro shops often use a fill rig connected to a number of compressed air cylinders (basically the same as you filling from a scuba tank, but on a larger scale) - they only have a finite supply of compressed air, where a compressor gives you an unlimited source of compressed air. Some pro shops also have a booster pump in order to charge up to 4500psi. Boosters aren't common at diving shops (that I have seen) - they either have a 4500psi capable compressor or they don't.

If anything, air from a diving shop will be cleaner, as it has to be breathing quality air, so it shouldn't be dirty.

A paintball shop *could* fill a scuba tank, but it would take a big hit out of one of their cylinders - they are really set up to fill a smaller air system bottle. Most of them would expect you to get your scuba tank filled at a diving shop with a compressor.

And the dive shop would charge much less to fill your scuba tank than the local paintball shop would.

ok this is my question

I am probably going to be running a private field for teams to practice on. I need to purchase some scuba tanks. Now there will probably be about 10-12 people playing on the weekend (Friday-Sunday). I was thinking about getting 2 tanks. How many times would i have to fill these tanks over that weekend period? Also if i want to do that cascading thing do i need to fill stations?

That is a very hard question to answer, as it would depend on a number of variables - the capacity and fill pressure of the scuba tanks, the capacity and fill pressure of the bottles being filled, the efficiency of the markers being used, the number of shots being fired per game, how many games in a day etc.

An easier question to answer is that regarding the fill station. It would be possible to function with just one fill station, but you would need to keep switching it between the bottles, so for speed and convenience, it would be better to two fill stations.

I know this is an old thread, but I'm planning on getting a scuba fill unit and a compressed air tank for my 'Cocker. How many shots could I get off of a 68 ci tank on average, and from what I've read so far, its best to get 2 3000 psi scuba tank and cascade? Would that get me up to 4500, or just 3000? I would think only 3000, but I'm just wondering. And if its only 2 guys filling off of the set up, and shooting maybe a case a week between the two of us, how long would this setup last for giving fills? And one last question, can a fire department fill a scuba tank? And I'm in Alberta, so a dive shop may be slightly hard to find. Thanks.

The very vague rule of thumb is that a 3000psi charge will give 10 shots per cubic inch of tank volume, while a 4500psi charge will give 15 shots per cubic inch. This would suggest that a 68ci tank charged to 3000psi would give 680 shots.

However, Autocockers are generally more efficient than this rule of thumb allows for, and with some tuning (sweet spot your regulator pressure, and use a spring kit to set the valve dwell), you should be able to get 1000 shots or so.

If you are using a 3000psi scuba tank, you can only fill your bottle to 3000psi, even if you have a couple of tanks. Each fill of your tank will be at a lower pressure than the last, as each time you tank air out of the scuba tank, the pressure drops. This is where the second tank comes in. It is just used to "top off" your air system to get you closer to 3000psi. This means that the pressure in the second tank drops off more slowly, as you are taking less air out of it.

If I already have the tanks how much will it most likely cost to get all the other equipment.

You would need a suitable fill station, depending on the valve your scuba tank is fitted with: -


A Clamp

http://www.planeteclipse.co.uk/site/....asp?prodID=17


DIN fitting - 4500psi

http://www.planeteclipse.co.uk/site/....asp?prodID=28

The links have converted the $US prices back to GB pounds for some reason..... They are $76.50 each.

Basically, the tank itself, and a suitable fill station to fit whatever type of valve the tank is fitted with.

A booster pump would be an option, in order to keep achieving the same air system fill pressure, even as the pressure in the bulk tank dropped.

easy to get. welding shop. bottle cheaper than a good hpa p/b tank. 11bux exchange.

This is correct. I know I can lease a 4500 psi bottle in Phoenix, AZ for $7.00 a month and 200.00 refundable deposit. It costs about 20.00 to fill it back up.

I'm not sure if my calculations are correct, but this is what I figure could be accomplish with a leased 4500psi Nitrogen cylinder from the welding shop:

Formula = P1 x V1 = P2 x V2
P1 = Source Pressure
V1 = Source Volume
P2 = Equalized Pressure
V2 = Total Volume (Source + Destination)

# P1 V1 P2 V2

Costs Assuming 40 Fills Per 4500psi Cylinder
Refundable Deposit 200.00
Monthly Lease 7.00
Cost to Fill Bottle ~20.00
Cost of Lease/Gas Per Fill 0.675
Difference to PB Shop Fills 2.575
Fill Station ~115
Fills until paid for ~65.6

Although you wouldn't want to go out for a day of paintball with less than 3000 psi in your tank, I think this way is viable because you could bring this tank with you in your truck, and fill throughout the day. Especially good for my buddies and I, because we play in the desert.

Here is a question ...

can I use basically the same idea on a larger K-bottle?

There is a single subcontractor who fills all the Fire Dept. SCBA tanks for the county I reside in.
He is not open to the public.

Unless you bring a booster into the equation.
I recently purchased a booster from rocket-booster.com

Here's my current set-up -

[#1 SCBA tank] -> [regulator] -> [booster (drive) ] ---> [Paintball HPA bottle]
[#2 SCBA tank] ----------------------> [booster(supply)]

My 4500psi 87cu.ft. carbon-fiber wrapped SCBA tanks are filled for $5.00 each at local scuba shop.
I use the Rocket Booster to fill my paintball tanks to 4500psi (as the scuba shop can only provide 4000psi fills)



For properly-rated interconnections and hoses, be sure to check-out Joe's website

I bought my first SCBA 'fill station' (aka 'SCBA Hose Assembly') from Joe, as well as micro-bore hoses.
