Are there canisters that can be ordered online already filled that aren't super large? In the US.
Where did you buy all this? Can you send links?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.

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?Here's my Rescue Hood setup:
- 9 Litre nitrogen cylinder(200 bar)
( BS341 no. 3, 5/8" BSP(British standard) outlet )
- Argon regulator with flow meter. (BSP/British standards - G 5/8" BSP inlet (to cylinder). G 3/8" BSP outlet (to coupling)
(~12.5lpm argon =15lpm nitrogen; will probably use 15lpm argon, = ~ 18lpm nitrogen).
- Rescue hood with 1 metre hose (CEN-type hose plug, compatible with CEJN 340 series and rectus 95 ks series couplings /couplers).
-Rectus 95ks female 3/8" BSP (British standard) coupling /coupler
- Adjustable wrench

Total cost(including postage) : approx €600(euros)
Cost breakdown in euros (approx) :
- 9L Nitrogen cylinder : €200
- Argon regulator with flow-meter: €110
- Rectus 95ks female coupling /coupler: €90
- Rescue Hood : €200
- (will also spend -~€15 on straps to strap to armchair)
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.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.

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: "That's a mistake, should actually be 137 bar for the 9litre cylinder.

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.

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"
|Max. Inlet Pressure||200 Bar|
|Inlet connection||G5/8″ Bullnose|
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?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 Pressure 200 Bar Inlet connection G5/8″ Bullnose Outlet connection G3/8″ Capacity 0-34l/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.
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.OK now I'm even more confused - I had no idea there were requirements for the regulator in terms of capacity.
