Question about nitrogen regulator

I picked up an old Uniweld nitrogen regulator from a friend a while back, and he was using it in his kegerator to dispense commercial beers. I'd like to use it with my 5# cylinder to force carb and for other misc. tasks. The problem is I'm not sure if the nitrogen PSI levels are the same as CO2 regulator PSI levels. If I dial this thing to 30 psi, is that the same regardless of the gas? I would assume so, but is there someone that knows for sure?

Looks kind of like this...but dirtier and older

so you're talking about putting a nitrogen regulator on a co2 tank? it'll work, but the valves are different. The co2 tank takes a cga320 valve. You'll have to get an adapter like this:

Yep, got one already...it's hooked up to my 5# CO2 tank right now.

Sorry for the crappy cell phone pix:

Then you're good to go.

psi is psi

It will work...the question you might want to ask is...

What is the pressure relief valve set for? In the first photo you had a regulator with a low pressure range of 0-600 psi. Now if you had a regulator malfunction (not likely...but possible) , would you want up to 600 psi going into your keg? I wouldn't have a problem connecting that kind of regulator to a manifold...and adding a 60PSI relief valve in the manifold...as an additional safety.

Most regulators sold for beverage use...have a safety relief valve set at or just above the range on the low pressure gauge. (unless someone swapped out gauges, and not relief valves)

Just something to consider...

PSI is PSI - But lets not forget about solubility of N.

Try using this calculator Maintaining Draft Beer Equilibrium

I did a Bitter with CO2 & Beer Gas.

Assume the following parameters; Ordinary Bitter, 1.3 Atmospheric Vol. 50F serving temp.

I did a Bitter with CO2 & Beer Gas.

Assume the following parameters; Ordinary Bitter, 1.3 Atmospheric Vol. 50F serving temp.

Pure - 100% CO2; Practical Pressure Setting - 2 psi

Lager Beer Gas - 60% CO2 | 40% N2; Practical Pressure Setting - 22 psi

Stout Gas - 25% CO2 | 75% N2; Out of range too high.

I don't think he is actually using nitrogen, just pure CO2 with a regulator that has gauges labeled for nitrogen.

and yes, a regulator is a regulator. Ideally I would consider putting a more appropriate safety valve in the system though, A cornie keg is rated for somewhere around 135 psi IIRC. A 60 psi safety would be an excellent choice.

Cool, thanks all!

Where did you get your "gas out" nut to barbed fitting that is on the regulator? Is that 1/2 inch nut reduced down to 5/16 inch barb?
