Ok ,I see you don't seem to have a regulator guage on the bottle,are you just guessing the flow rate?where on earth did you get the exit hood?it seems a set up that is achievable but I'm no expert,I presume that if argon is heavier than air more chance of it escaping from the bottom of the hood ,but enough gas is put in it probably won't matter as long as the flow is constant for long enough.i hope it works out,looking at the hard facts in pictures makes death very final and empty.needs must I guess.
That's not my setup but from someone who I think successfully ctb using that method.
The bottle has a built in regulator between 0.5-50 bar, I use the same brand but with nitrogen and a smaller at 5 liters.
The bag seems prefabricated but I don't know where he got it, seems quite good.
It seems he didn't use a flow meter and just guessed the flow rate, but he used the big bottle of 11 liter. Which will last quite long even at 30 liter per minute maybe an hour at that rate. The excess gas probably flowed out around the neck and made more sound than at a lower lpm.
If enough gas is put in the bag it will displace the oxygen and you will breath argon, the importance of keeping the gas flowing is more crucial since it will sink to the floor. But judging of the picture it seems to work.
It's a strange feeling building this contraption, it will either scare you or give you great satisfaction. I'm more on the scared part since it will enable me to ctb with very short notice.
Are you going with a bag? You may be interested in with the hood, works similarly but with the option of breathing out co2
NITROGEN GAS WITH EEBD HOOD (INERT GAS METHOD) before I start this guide, letās be honest this method is expensive (approximately 600 to 800 dollars)and you need minimum 1 -2 months to source the equipments and nitrogen gas cylinder. My tip for you to do it cheap, purchase the Chinese products...
