Tuning How many fills?

[Richard300]

Hi. I have a air venturi avenger in .22 on order. It has a 180cc tank on it. I have a scott scba 45 min tank to fill from. It will start out at 4350 psi. I will be shooting the tank on the avenger down to 1800 psi. How do I figure out how many fills I will get out of the scba tank before it reaches 1800 psi. Im guessing some of you will know this from past shooting. Any info on this would be great. Thanks

Pyramyd Air has a calculator to figure it out (approximately). Probably other sites also.

I use to take mine to a dive shop... but there to old now so they wont fill them. I bought a yeng heng compressor works great so far.
