My setup:

125cf Nitrogen Tank

Nitrogen Regulator (also came with the yellow 7.8ft regulator hose)

Nitrogen Flowmeter

3M Versaflo Hood (had to buy both the breathing tube and breathing tube-adapter separately, so 3 purchases in total)

1/4 hose barb to male flare brass fitting (needed this to connect from the flowmeter to the hose then to the breathing tube)

Pack of 25 1-inch outside diameter x 1/4-inch inside diameter rubber washers (Had to use these to act as a seal for the breathing tube. Fitting about 7 rubber washers on the hose bare section of the brass fitting until only the tip was exposed,)

Are there canisters that can be ordered online already filled that aren't super large? In the US. I can't leave the house without anyone being very suspicious, unfortunately. I haven't considered this method because of the difficulty in getting supplies. I could intercept mail but it would be tricky.

Here's my bus. It's closely based on @GasMonkey 's setup, so I'm just posting some details.
Feels good to know I have the exit ready to go, when the time comes.
I studied so many methods, and I'm thrilled by how smooth SCBA seems to work.
Thank you to everyone who helped me make it happen.

In the US nowadays they don't ship small Nitrogen cylinders full, probably because there were too many people using them to CTB. You have to buy one empty and fill it locally, or buy a big one full.​

Sorry, posting links or direct info about sources is not allowed :/


You'll have to do your homework and read through the inert gas forums threads.
It's time consuming, but thank goodness the information is even accessible here.
It's not a simple subject, it's important to really get to know it technically, to do things right, and unfortunately there are no shortcuts to understanding it.

Eebd hood setup (Nitrogen)

My setup

IMG 0372

Process to test the setup:

Before everything make sure there are no leaks, leaks are a huge problem in nitrogen gas setup.

You have to test whether 0% oxygen environment can be achieved in the eebd hood or not, to be successful oxygen level should be less than 1%

You need a dummy head, put the eebd hood on the dummy head, put the oxygen detector inside the eebd hood but make sure you see the readings, finally open the cylinder valve and check the readings, if the oxygen detector reading goes less than 1% your eebd hood setup is good to go

Before testing oxygen detector picture below:

IMG 0332


After switching on the nitrogen gas, it went to zero level and it was fast, no one surviving that lol (this happened at 20lpm within 20sec)

IMG 0363


Check the reading, oxygen level went to zero which mean your setup is working, please refer the below image

-Rectus 95ks female 3/8" BSP (British standard) coupling /coupler

Thanks for useful post. I was looking at same regulator but the vendor just emailed me to say it is not suitable for a nitrogen tank so I am stumped now. Can I ask where you got a 9l tank at 200 bar?

That's a mistake, should actually be 137 bar for the 9litre cylinder. I had a 2l cylinder at 200 bar, but changed to a larger cylinder. I got mixed up. Can no longer edit the post to change it.

How is it not suitable? Once the regulator inlet matches the cylinder outlet, and is able to take the bar pressure of the cylinder (e.g. the max pressure outlet on my regulator is 200 bar), then I don't see what the problem is.
Did the vendor just mean the guage and flowmeter are set for Argon and not nitrogen? If that's the only reason, then it's fine, you can just do the LPM conversion.

OK because the cylinder i'm looking at is 9l at 137 bar. About the regulator, yes that's what I thought, I sent them the valve info for the nitrogen cylinder to ask if their reg would fit and they said: "
sorry no the below regulator would not suit for Nitrogen as it is a argon/argon mix regulator.
If you can get me more info on the style of nitrogen reg you need I could possible have a look and see what I can get to supply. Info needed would be outlet pressure correct fittings and what it is for etc"

Seems like their issue was just using an argon regulator with nitrogen, as opposed to the fittings connecting?

The reason I bought an argon regulator was because I found it easier to get one with a flowmeter; I just couldn't find a nitrogen regulator with flowmeter or with an LPM guage that shipped to where I am. You might be able to find one.

Your cylinder is 137 bar . You need a regulator with a greater maximum inlet pressure.
You are in UK? So your cylinder bought in UK should have had a BS341 No. 3 outlet valve. That's the standard. Measurement is given as G 5/8". (Sometimes called a bullnose outlet).
So you need a regulator with an inlet valve that matches that. The outlet valve (that the coupling attaches onto) on the regulator will probably be 3/8" BSP. (Its the usual UK standard).

Here's a sample info piece for an argon regulator with flowmeter (British standard):

Max. Inlet Pressure200 Bar
Inlet connectionG5/8″ Bullnose
Outlet connectionG3/8″
Capacity0-34l/min


So just say the regulator must have litres per minute (LPM) on the guage or come with an LPM flowmeter. With a maximum inlet pressure greater than 137 bar, inlet connection G5/8" bullnose, outlet connection G3/8". And make sure the LPM capacity of the regulator is greater than 15 LPM if you are setting it to 15 LPM or higher when ctb (e.g. above one states 34 LPM capacity).
They asked what is it for? Can be used in welding, for example.

OK now I'm even more confused - I had no idea there were requirements for the regulator in terms of capacity. So if I get the same one you got, it should work with my tank?

Regulator gauge/flowmeter litre per minute (LPM) varies. I saw one regulator flowmeter that only went from 0-1.3 LPM. That's obviously no good to you if you want to set it to 15 LPM. Some flowmeters are 0-15 LPM, which is fine if you're definitely setting it to 15 LPM; if you're setting higher LPM it's obviously not high enough.

If your nitrogen tank has the same G5/8" bullnose BSP connection mine has, then yeah, it'll fit.

These photos are impressive. You guys have a lot of skills and knowledge that is beyond many if not most people's capabilities. I couldn't manage these sorts of elaborate setups.

Nitrogen is tricky because you cannot allow it to mix with oxygen as you breathe it. I won't go into details of what may happen if you breathe in oxygen mixed with your nitrogen but it's not good.
