Newb question on tank capacity

[Hummer57]

I’m want to buy a used scuba tank, 4500 psi, 45 minute. 

1. How many fills will this give me an Akela?

2. What extras are required to fill the tank and gun?

I have aYH compressor.

Thanks for the help!

The only advice I can give is that both Pyramyd Air and Airguns of Arizona have great calculators ( on their website) to help with answering your questions.

Took a 45 min tank with 4300# a 250cc gun at 3000# and fill at 1500# and got 21 fills. Don't know what you gun hold or fill point but that's a fair WAG. Scuba tanks and SCBA are two different animals. A SCBA with a fill station would set you up out of date because you have the compressor under $200 would set you up.

Thanks Len, that’s what I needed to know.
