Has anyone done a nitrogen setup yet?  Curious to see what it will cost to set up.

Thanks for posting the price list.
Wonder about finding a regulator and gauge set up for it.

Used them for years. Company I worked for had 3ea 6000 psi bottles. I filled directly off the bottle no reg until later. Go slow and pay attention. Your better off to buy the bottle and have it filled when needed.

 Could a guy feed a shoebox with the  nitrogen tank when it gets below 3k as long as you keep the psi to the shoe box below 90psi,it would be clean and dry????

Absolutely , once your tank is below the 3000psi mark ,plumb it into the shoebox and fill a guppy tank from that. That way you could use the tank(nitrogen)  all the way down to 85 psi ( enough to feed the shoebox)
The only downside is having to buy a second tank good for 4500 psi.

I have a question regarding the nitrogen for those in the know . How much fps would be lost as compared to compressed air at the same PSI?

Or... Helium?
« Reply #10 on: April 06, 2016, 03:22:53 PM »
I have wondered more about helium than nitrogen. Obviously, some of the same issues (pressure, regulation, etc.) apply, but the gas itself is somewhat lighter. That fact, should allow faster velocities at any given pressure.

And, if you get crazy, you can breathe in some helium, and talk like Donald Duck! Just kidding!

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.

As from I know and have read, you gain fps with nitrogen.  Not sure how much, but enough to notice.

The gain with Nitrogen is small but measurable....

Price and setup cost depend on who you are and were you live.

I'm a moble welder, I get a discount at the welding supply store. I pay about $70.00 a month for 2 (k) oxigen bottles, 2 (#4) acetylene bottles.  It would be around $100 for anyone just coming off the street. Mind you, that's just the rental, refills are about $20, $30 respectfully.

For two years I also rented a 6K and keep it in the garage to fill my 88cuft or guppy tank. 
Cost: Joe B 6k reg $145-160 don't remember but it was not cheep.
          6k rental fee: it went from $60 a month to about $100 a month. Gave it up a year ago was not worth the price.
            6K refills were about $110
             6K bottles weigh anywhere from 200-300 lbs.
Without my discount, it would be at least 1/3 more

I have heard it can be got cheaper in other regions of the country if they will even rent to you,  but here I California
My price was about as good as you can get.

If you already have a good fill assembly rated at the proper pressures such as found at MAC1. All you need to do is go to a local AIRGAS or similar location and they can sell you two simple pieces that simply go where the SCBA/DIN adapter and shaft would go on the cross connector. Simple as that. No need to go running to Joe over anything. I am partial to Airhog anyways.



After you have that simple set-up, then you can buy or rent a 6K Nitrogen Tank. Good idea to have a buddy to help with unloading it as well. Some rent by the year, some by the month, some only sell them and they ALL charge for re-fills.
