Compressed air in a tank.

by Lenny
(B.C. Canada)

If I have 2,000 lbs of compressed air and I'm blowing off 35 lbs How long will that 2,000 lbs last me? Hours and minutes Please. xangolenny@hotmail.com





Bill doesn't even try to answer...

Hey Lenny, thanks for the question, but frankly, I haven't a clue.

I've only ever worked with industrial compressed air in the 100-150 PSI range, and I sure don't ever use compressed air measured in pounds.

Sounds like you're into the diving business, and that's not my line.

However, we get a lot of visitors to these pages, so I'll ask, if anyone can help, please add a comment for Lenny.

Cheers,

Bill

 Measure air by volume
by: MEP1

You can't gauge how long a tank of air will last given a usage in pressure. You need to provide exactly the CFM (Cubic Feet per Minute) you're using as well as the size of the tank pressured to 3,000 PSI, then someone really good in math can determine for how many minutes that tank can provide your usage of air. Trying to determine usage by pressure would be like trying to determine the pressure coming out of a garden hose by throwing the end in a bucket and seeing how long it takes to fill.

 Compressed air in a tank.
by: Lenny

Thanks Bill,


Let me explain what I'm doing. I'm a Custom Hand Engraver and my engraver runs at 35 psi. I would like to make it portable without using an electric compressor. I'm thinking of using compressed air, something like a tank that would hold say 2,000 lbs or even a dive tank, I think they hold about 3,000 lbs If I was to turn on my engraver at 35 psi how long would it run on 2,000 lbs?

Cheers,
