Air Tank

[Ricko1966]

@AuroraGirl I made this just for you,well, just for me but I was thinking of you. I lost my favorite air bubble(freon tank) had it 30 years. Needed something now, I told you you could do this months ago so I'm showing you how. 1 old school BBQ tank,the kind they won't refill,1 BBQ regulator, 1 air hose coupler,and 2 air fittings. You take the brass fitting out of the regulator,look at it,the hole in the center is the size of a pin,drill the hole bigger,screw it to the BBQ tank,screw the coupler on. To fill it take the 2 air fittings,as in the picture,hook one end to the coupler,1 end to your air compressor hose,open the valve it will fill. Close the valve, disconnect the air hoses and you're done. With the valve closed it won't bleed off over time like the parts store air tanks. Pic 1 old propane tank coupled to my compressor hose. Pic 2 the regulator I took the fitting from,the 2 air fittings I couple the tank with to fill,and a coupler screwed to the regulator fitting. Pic 3 the air fittings,in the coupler,ready for filling the tank.

So how do you know when its full?

When it quits taking air it has as much air as my compressor tank. I could unscrew the LP gauge and put an iron gauge,if I wanted,or I could screw an air coupler to a gauge and pop it on the hose if I wanted to check.

but like, lets say you have a big compressor that goes pretty high , 50 gallon tank, 3-5 hp motor, i forget the max psi but is there a risk or danger of exceeding its safe capacity?

No, there is a pressure relief,I think on propane tanks its 400lbs,I'll double check,but these tanks are overkill, even my freon tank I always just coupled it to my air hose 135lbs,regularly. Open these links,20lb cylinders can have 200/ 300 psi in them depending on temperature.

Understanding Proper Propane Tank Pressure!

How much pressure is in my propane tank? According to the national standards publication NFPA58, a propane tank with 20 pounds (5 Gal) of gas at 70°F would have a pressure of 145 psi; at 90°F, pressure would increase to 180 psi; at 105°F, pressure continues to rise to 235 psi, and at 130°F...
