***Official price for the ShoeBox compressor will be 390 dollars***

Yes there is a 1/8 pipe tapped port on the compressor.

Most of the typical braided stainless lines are NOT rated for 4500 psi.

Virtually all brass fittings are not rated for 4500 psi.

The compressor has a male fitting for the output.

You need a hose with two females.

So stupid question...the first round of Shoeboxes are 4500psi models. If I hook it up to a 4500 psi bottle, sit there and watch it for X hours while it fills (yes, I have no life), and manually turn the Shoebox off when the tank gauge reaches 3000 psi, does that mean I can also hook up a 3000 psi bottle, sit there and watch it for X hours, and manually turn the Shoebox off when then tank gauge reads 3000 psi?

Definitely don't want to cause any safety issues..but it seems to me that since this is not an "instant fill" like a typical system, as long as you are actually paying attention to the fill process, you could fill 3000 psi tanks from the 4500 psi system. Am I missing something?

If someone else want to weigh in on this, go ahead. But I'm fairly positive the answer is "YES, you can do this". The compressor has to get to 3000 psi before it gets to 4500 psi, and it won't jump from 2800 to 3700 all of a sudden. If you are watching it, just turn it off when it gets to 3k.

I had a discussion with someone about this in one of the other compressor threads. Basically, you can find out how long it takes to fill an empty tank up to 3k psi, let's say 2 hours. Get a timer that you can plug the ShoeBox and shop compressor into. Set the timer for 2 hours. It will shut everything off after 2 hours and you should have a full 3k psi tank without having to watch it.

that's exactly what tom said when someone asked him a similar question on facebook.

That's pretty much what I was thinking...except with a "walk away and let the timer take over" situation I'd probably say 1.5 hours instead of 2, just for extra margin.

I guess worst case you come back, find your burst disc blown and the compressor is pumping air out into ambient through the disc hole.

Right, the 2 hour thing was just round number, Tom said that the fill is linear, so if it in fact takes 4 hours to fill a completely empty 4500 bottle, then that's 1125 psi per hour. So 3000/1125=2.67 hours. Though I'd run a couple empties though first and see exactly how long it does take.

The high pressure burst disk on 3k psi tanks is 5000 psi, so even if you do forget and fill past 3k, you shouldn't have any problems, just shouldn't let it happen a lot. Tanks are hydro tested to 5/3 their designated pressure, so a 3000 psi tank is capable of holding 5000 (and probably more) psi.

I was looking at the 4500 psi capable hoses and they are not that cheap. I've found some for $60 and up and nothing on paintball web sites.

This one was the cheapest I could find:

Would that one be a correct hose to be used for this application?

Also, would the standard quick disconnect fittings we usually use stand that pressure?

Please advice.

Thanks,

Tom said it wouldn't be safe to use it because of the time under which it would be exposed on such high PSI, didn't he?

[slick86]

didn't see that, just needs two female ends.

Ninja sells a 3000psi one

I'm sure they will sell the 4500 ones if enough ask imo

I am talking to Ninja about having the proper hose.

I will let everyone know a cost once it is available.

I think we're going to need a bleed too, or is there one built into the compressor?

Ninja techs seems to not want to answer my questions directly.

Taken from BigEvil review on the compressor:

There is also a bleeder knob on the bottom front right above the output nipple
