It's not any of the tanks listed in the huron chart, in fact I've never seen specs on this particular tank. I remember when I borrowed it a few years back I tried to find out it's capacity but couldn't find it on any charts. I know for a fact it was purchased at a LDS new, so somehow faber made this model and distributed it in the U.S.
That 22.25" is with the boot on, right? Closest thing in size would be the HP80, but a little taller with a lower service pressure. My guess its that at 3000PSI, you're getting around 80 cft. It would be nice to know the buoyancy; my memory is that it's slightly negative empty.
I just looked up on the faber site. M8303 is the DOT code for faber cylinders sold in the U.S. They have two cylinders listed in their catalogue with 7.24" diameter and 3000 PSI service rating (2730+10%). They don't list height, but the capacities are listed as 677cu/in and 793 cu/in water capacity. I bet yours is the smaller one. I think you can dig further to find air capacity, or just do some math. I did a little (677cu/in=.39 cu/ft times 208 (pressure in at-1) and I came up with about 81 cu/ft. But I'm lousy at math so some kind soul will certainly come forward to correct me.
