Min presure to full HPA tank

[JSC_Liason_neo]

If i was to get a 91cu hpa tank can i fill a 68cu tank with a remote?
Whats the min presure needed to fill a hpa tank?

This is for longer games meaning i can carry 68+91=159cu of air

dont quote me on this, but a remote line I THINK is only good for about 1000 PSI. Whereas your cylinders will be up to 4500 PSI.

I have a ninja remote and it can handle 3000psi

if your talking about a 91ci paintball tank you would only be able to get the 850/650 psi the reg alows through anyways so you would have to get somesort of replacement for the reg that allows full preasure tank filling, tho to me that just sounds like playing with match's

as wol-gran said the 68 cu tank will fill till the air pressure equalises between the two which would be reg pressure. tHe only way around that would be to take the gauge out of the reg and put in a T fitting. screw the reg in one side of the T and 2 taps and female fillnipple connecter would need to be setup like a fill station. one tap and connector for fill and one tap for pressure relief after filing. It would be to big and bulky to carry while playing not to mention dangerous. if you are happy to carry a spare tank i would suggest just carrying another 68cu and switch when empty.

you could also try taking two tanks with the same output psi and joining them in parallel. By this i mean get a T fitting and two remoteline tank ends with no hose. Screw the remoteline ends on to the tanks. You will need to get 2 short pipes / hoses to go between the remote line ends and the T fitting. I would go to pirtek of something like and get some made. The connect your remote line to the remaining T fitting port. I believe that because they are connected in parallel it will still only have reg output pressure at the T fitting port / you remote line. Both tanks should be turned on when in use. Would strongly recommend putting a gauge on the output port of the T fitting before connecting to marker, or remote line just to double check pressure. This will give you double the tank capacity of a 68 cu with out having to swap out tanks or fill. I believe that if the output pressure is the same friom both regs then you should be able to turn both tanks on at the same time and they will empty together and the same rate giving you a 136 cu capacity. I Have not done this and am not 100% sure it will work but its just an idea i was going to try for bushball but never got round to doing it. The other thing is you will obviously have to run this setup on your back with remote line. If you have any questions pm me i did up some basic drawing for the design i could send you.

jeez. what a lot of blather. just run your 68 on marker and your 91 on your back. run a remote line from your 91s output to your 68s input. as your 68 empties, it will draw from your 91 to equalise the pressure. even if the output of your 91 is slower than your 68, it won't matter unless you are going to run your 68 dry in one continuous burst. during the times you aren't firing, the two tanks will continue to equalise.

the only problem that i can forsee is if you use two different pressure tanks, in which case, same proceedure, just make sure that the 4500psi is "on gun" and the 3000 is on your back. the 3k then won't come into use until the 4.5k tank drops under 3k. easy ;-)

hope this helps.

sorry T, gotta disagree with you on using 3000psi and 4500psi together. they will both be supplying the output needed, say 850psi of the regulator, the 3k will dropout first.

DONT try bridge the 4,5k and 3k psi tanks through the fill nipples, do it after the regulator

X2 only way to go

How much paint are u looking at useing between fills??? are u going to drag a trailer arround with you for the boxes of paint? Just strap a scuba tank on and away u go.

Sorry Tim, I wasn't advocating the use of them together. I don't know what airsystems JSC has, so I was just offering a possible solution. As I understand it,the on-gun airsystem is the one supplying air to the marker. As such, the regulator on THAT airsystem is the only one that matters to the operation of the marker. As the fill nipple on that airsystem is BEFORE the output regulator, it has the entire pressure of the bottle (4.5k when full) holding it closed.

My initial thoughts were that the on-gun bottle would have to drop below the pressure of the secondary tank to initialise a cascade fill from the secondary to the on-gun system eg. the 4.5 would have to drop below 3k if using a 3k secondary. But having mulled over your objections I saw the flaw in my plan. I didn't take into account the reg on the secondary tank would come into play, limiting the actual output of the tank to less than 1k, so the primary tank pressure would have to be under the output of the secondary tanks reg to allow it to come into play.

Hmmm. still think it's possible if you remove some shimms to increase the secondarys output to about 1.5k....
