Shoebox won't fill carbon fiber tank.

[wtravis1]

I have a shoebox and have been filling my armada and wildcat from it regularly. I bought a 100 cu ft ( I think) carbon fiber tank from AOA.
The shoebox just runs and runs (up to an hour) and no pressure reads on the tank. Everything from the shoebox runs through a dryer and I can hook up and fill a rifle no problem. Hook up the carbon fiber tank and nothing, nada.
Anybody have any ideas?

What did AOA say?

I'd say spray some soapy water around the valve of your CF tank and check for leaks.

You likely will NOT see any raise in the gauge after "only" an hour. You do realize it will take 30+ hours just to get to 3K, right?
According to the below link it takes 24hrs for the regular shoebox to get an 80CF tank from 0-3000.

I just bought the 98 cu ft tank and its filling as I type. It's gonna take many hours to fill that big tank from empty to 4500. Mine has been running about 5hrs straight and its at 1300 psi so far. The fill times are posted somewhere on the forums either here or shoebox but 1hr will definitely not fill it. I think you are looking at overnight plus an afternoon of filling.

If you still have no pressure check to make sure everything is tight and not leaking. Also, make sure all the relief valves are in the closed position. I left it open on the shoebox many times and the air just leaked out of the valve.

Have not been able to get in touch with AOA but you guys have given me some things to check.
Thanks

 

[wtravis1]

You were right. I just let it run and it's filling just fine
Don't know what I'd do without these forums.
Thanks

You may want to have a fill center do the initial fill. Even getting it to 3,000 psi could save you hours of monitoring. Many guys with a shoebox refill at level where it only takes an evening to refill (say for example 3500 psi).

I'm sure you know, but you have to open the tank while your filling it.

I try not to let my tank drop below 3500. At that setting it takes about 5 hrs to fill up to 4500 as I remember.

If you can, go to somewhere to at least get it filled to 3000 psi. As other posters have said, filling up from zero will take you into next year some time ;- )
