Is it ok to use all the air in a tank? I’ve got a 66 cubic feet Air Venturi tank. I heard that you’re not supposed to use all the air in a tank because water could get in. Is this true? What if water does get in? How would you know?

Only way moisture gets in is if tank sweats from thermal extremes or pump system filling said tank lacks water / moisture filtration.
No need or reason to use all the air from a tank below whatever your gun/s minimal fill pressure would be. Stop there and refill !!

If you bleed your tank fast, water will be in it.
It's okay to drain it slowly, visually inspect, change valve if needed.
Just don't let the air out fast. If it's cold air, it's too fast.

What you might be referring to is for Scuba tanks.
A scuba fill station will not fill an empty tank without first a vi$ual inspection if tank is still in its 1 year from last inspection. Thats because scuba are overwhelmingly used under water and if all the air is gone good chance tank could have ingested water...
But as MH said, 0 psi should never be an issue for a scba/scuba tank used for pcp....

That is THERMAL extreme ..... As air leaves tank fast there is a chilling effect similar to a Heating effect if you fill the guns tank to fast.
Low to high pressure creates HEAT ....... High to low pressure creates chilling and sweating of the tank.
FACT ..................

When I went scuba certification many years ago, we were taught to always keep at 100 psi in the tank to keep debris out of the tank and valve.

Under what circumstance would you "use all the air"? Most PCP's fill to 3000 psi. A few only to 2000 psi. Why would you run your tank below that level ? Unless you are going to use it to fill your tires or something.

I mean using it all up by refilling multiple times. Of course I don’t mean just dumping a full air tank into a 480cc carbon fiber bottle. I would be in the hospital if I did that lol.

I don't think you are asking the question complete enough. Try asking more in depth. I can't figure out what you are asking. One can only fill from a tank to a level psi the gun can use. You can only use the air in a guns tank to a point where the gun works correctly.

Where did you hear that…?
It's called PHYSICS! When one FILLS a tank the air as it is pressurized HEATS the tank (Adiabatic heating). When one RELEASES the air it cools the tank. The Yin & Yang of Nature.

Hi
I don't understand physics I have not been a great student, an air conditioner compresses gas and then releases it and produces cold and if in that process it produces water, that is why the air conditioners throw water due to cooling but it is external due to condensation if water were produced in inside I think the air conditioning would break
Edit: I don't understand how you can empty a tank to 0 by recharging a pcp

Why would you ? Your guns need so many psi to shoot well... Anything left in the tank stays there and there is no need to empty..

Just me, but I would be more concern with how are you filling the tank up? Because if you are filling the tank with your own small compressor, it is a lot of run time to fill from empty. Can your compressor handle that much runtime?
