Multiple air tanks

[Chuck E Ducky]

Why couldn’t you just remove the 13ci reg guts hook a remote line to it permanently and fill them both at the same time. It would give you the same results and all your parts attached would be rated to your required pressure. The 13 would just act at a pass threw but hold more air volume. Like a big expansion chamber.

You could probably remove the pin shims and piston. It would then just act as a pass threw and as long as your remote line was attached and on would fill the 13ci at the same time. Just don’t fill it higher then the 13ci is rated for (3k)

Few problems with that

1) if you remove the guts it will leak, look at the animation I have above, see that hole next to the piston? It's there because the volume of that chamber changes as the piston moves, remove the piston and you create a leak there. Most regs have that hole because without it the regulator can be sluggish/inconsistent

2) even if that's not the case and it doesn't have that hole, the remote lines are not rated for 3k, you would have to get a fill whip

3) and even if you did get a fill whip, you wouldn't be filling the 77 unless the line is hooked into the fill nipple. You can't back fill through a regulator because it's the output side that closes the regulator. If you increase the pressure on the output side it will just hold the regulator closed and your are also risking damaging the seat

The way he has it set up should work, if I get some time tomorrow I'll test it because I have everything already

Also, if the 13ci is just going to act as an x chamber, you might as well ditch it and just run the 77 in remote setup. There's no advantage to having the 13 there with only enough air to fire a few shots

One question for the op though, are you even going to be able to carry enough paint to make 2 tanks worth it? The phenom isn't the most efficient design but you will still be closing in on a full case of paint to empty both tanks

It’s only going to fill the wip and 2nd tank with regulated pressure off the 77ci. It won’t leak as long as it’s attached to the marker and the Air wip is functioning properly. It’s acting as a pass threw at that point. You would fill the 77 just like you would with any remote line setup. Basically charge the 77 let up, it will balance the pressure in the 13 to whatever the 77 reg is set to.

If you are talking not removing the guts of the 13 then yes, this works but then there's also no real reason to have the 13 on the marker either, just remote line straight into the ASA and go with an adjustable stock

If he wants to fill both tanks this also works (get an asa with a slide check to make life easy) my only question is if there will be any flow rate issues (testing in a few, just got home)

If you want him to remove the guts of either regulator and either one is any kind of a halfway modern design, it will cause a fairly substantial leak

It only half worked. There's a flow rate issue. At low bps it works fine but start cranking up the rounds and it falls on its face

My tank on the scuba is outputting 850 so yeah, shp output needed if you want a chance at making this work for anything over 5bps I'd say

Thanks for testing. I'll only be using 1 remote, with the 13ci direct fed to the ASA, so I think some of the volume restriction should be mitigated. The 13ci should just be acting as a big ass expansion chamber.

Cool, thanks for testing.

The plan again, is to use the 13ci and have the 77ci in reserve. The mobility offered by the 13ci as a Stock has a lot of advantages I don't want to give up, mostly freedom of movement.

I am not trying to fill the 13ci from the 77ci, just to use the 77ci through the 13ci if/when I need too.
I get about 125 shot off a 13ci, which is 6 magazines at 114 shots, so I should theoretically be ok, unless the battle gets really long, which for Fulda it very well could.

I did a little testing as well and I think it will actually work just fine with the 13ci. The tank volume is quite small and seems to recharge quickly. I will mostly be shooting semi so I don't expect to need the air volume for high bps. I also went ahead and adjusted the output pressure on the tank to ~900 psi.

There are of course much simpler, easier methods to this madness. I could just run remote. I could also buy more 13ci tanks. But that's too easy :P I also don't have another 13ci, but I do have a remote and this fancy 77ci, which is very light. Not to mention these extra parts not being used...

You could run a gas through T stock. May be lighter than the 13 even.

Or is there a way to input air in front of the trigger frame? I swear I saw that somewhere. If so just input the 77 there instead

On a phenom? That sounds wild and crazy and I have no idea how that might be done, but sounds interesting. The gas line is on the back of the Flex Valve, on the bottom just in front of the rear cap.

The A5 has the air in front of the frame.
