Shipping air tanks
« on: February 22, 2016, 12:12:47 PM »
I've read that some companies ship air tanks fully filled up to 4,500 PSI. If they do, it is against ICC rules. But this brings up another issue—filling them once you get them.

I've finally found someone close to Roswell, NM who can fill a carbon fiber tank to 4,500 PSI, but they're nearly 20 some miles away and they refill them overnight (read that as two round trips)! Since I really don't want the expense of owning a compressor that I would use once a year, perhaps this isn't such a bad deal. However, when you add in the $25 they want to do so, it becomes an irritant.

I wonder what others do who do not own a compressor (save for a hand pump), and need to fill their tanks? Do you drive 100 miles just to do it?

I have an Omega compressor. If you're a fellow Guild member, and you pass through Roswell, NM, I'll fill your portable tank as a courtesy.

Yes, I use to, in fact more than 100 miles, and it was a 3000 psi tank that wouldn't even give my one complete fill, because after the tank cooled I was lucky to have 2800 psi.... My round trip was 3.5 hours on the highway, plus the time to fill the tank.... There was no place within a 7 hour round trip that could even fill to 4500 psi....

That's why I bought a ShoeBox.... After over 500 hours on it, I upgraded to a Freedom 8....

Funny thing about nitrogen. One of the Saturday breakfast bunch is the owner of a local welding supply firm. He suggested helium. He says (I haven't tried either gas) it give better velocities than nitrogen. Well, it is lighter (An 2 vs. An 7), so maybe he's right.

Even funnier, I've know they guy for several years and never knew he was into airguns!

The Molecular (atomic in the case of Helium) Weight is an even larger ratio.... He = 4.... N2 = 28.... 7 times as heavy.... Air averages out to 29....

I only posted the "standard" atomic weights, so yes you're correct.
