Regulator or no regulator?
« on: March 19, 2016, 03:11:32 PM »
I bought a Shoebox Freedom 8, along with an 18 cubic foot composite fiber tank. The Freedom8 has an automatic shutoff built in. Following the directions, I reset the regulator. It now shuts off at 4,600 psi which is close enough. That last 500 psi or so, gives me 4 or 5 more refills over the stock setting of just shy of 4,000 psi.

I was a bit worried about filling my AT44 without using an externally-regulated tank to refill it, but have been reassured several times by knowable folks, that it wasn't necessary. Turns out they're correct. Filling to the exact maximum is a no brainer. However, I've read where others won't even think PCP without owning a regulator to make darn sure they don't blow up the storage container, whatever it is. And, some folks purposely purchased airguns capable of handling 4,500 psi safely, just to be on the safe side. I don't fault that reasoning, but I wonder just how important it is?

So, the question is, do you, or don't you use a regulated tank?

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.

Having 2 compressors now, an older ShoeBox 4500 and an Alpha 90 ..... seldom do I fill guns directly off the compressors.
This two fold ... by going into a bulk storage bottle condensation become less going into guns tank and also having better control of actual fill speed and pressure trusting a far more accurate mechanical gauge of the bottles valve set.

As to the regulated Q at fill devise ... with many bottles having Microbore hoses and slo-fill valves you get very good fill control dumping 4500 into a 3000 vessel.
The small NINJA type fill bottles with output regulators personally found a major PITA having sub 3k output, many blown burst disks filling off the HP compressors.

Scott, how does the little check valve that that you made work?  Never heard back from you.  As far as filling a rifle over 3200 or so I would never do it above that on my Mrods.

Not sure of what check valve you speak ? * If the Alpha, so far so good tho only @ 6 hours on it thus far.
Filling of 3K rated guns, never exceed 10% of that ( 3300 )  just aiming for 3K more fills than not.
