Re: Is my co2 pressure safe?
The Azoo is a set-pressure regulator. There's no fiddling with it. My main concern was the tank pressure, which was waaaaay above normal. The tank was only rated for 1800psi. I called the welding place and he said the tank had to be overfilled and walked me through some tests to make sure nothing had been damaged. Then he told me to take the cylinder outside and slowly bleed it. My 10 gallon tank had about 14-15lbs of CO2 in it, over 50% more than the safe limit!!!
By removing about 4 lbs of liquid CO2 from my cylinder, my pressure dropped from 2,200 psi to 870 psi, which is a normal reading for my room temperature. That's insane how high it was. An aluminum cylinder and an Azoo regulator can handle some pressure people.
Put it like this, I bled the tank with the regulator removed for like 15 minutes to get the weight to where it should have been. 14.8 tare weight plus 10lbs o2 is 24.8. My tank weighed like 30lbs!
Sad thing is I had to watch 6 months of free CO2 evaporate.
But at least my cylinder won't become an airborne projectile.
The needle valve on this thing is wonderful. I can drop the bubble count waay low if I want to, which isn't necessary, but is a good indicator that the valve is sensitive to finite adjustments.
AND this proves that the Azoo can handle insane pressures for at least a short period of time, which is good to know.
