internal volume/water volume is the only one you can compare
The main column label ya want on the other post is the second from left....compare that to the below major sources of tanks in US
So the INOCOM chart lists an internal volume of 416/418 how does that compare to the Big 3 stated capacities?? It has nothing to do with reserve capacities of air. Air does not compress like the simple math shows above 3000 psi. Multiplying internal volume times fill pressure and converting to cubic feet does not get you accurate capacity above 3000 PSI. That is why the biggest tank maker in country says 65 cubic feet of air fits into a 418 CI internal volume tank.
At least INOCOM is from Korea not China but I can easily get a US made one from a tank specialist and not an air rifle dealer that started the capacity wars to try and grab market share. I see they now list 550 CI tank at 100 cubic feet now on their website....Do you think INOCOM changed the production line to make them exclusive oddball sized tanks?? I will point out they fail to show the DOT spec label in their ads. Post a shot of your "75" tank DOT Label I bet the REE hydro test number is the same as my 66/45 min SCI tanks label
Think of it like the nonstandard audio amplifier power wars lies in 70S....yea the amp makes 125 watts but at 25% THD....really at usable THD levels the amp was 63 watts or so...
