Omega Carbon Fiber Tanks - Need Advice!
« on: February 26, 2017, 05:45:53 PM »
So I am new to air gunning and this guild.  I have a Marauder Gen II .25 and have really enjoyed shooting it so far.  But, I have to do something about a fill station.  I have found a decent deal on a Omega Carbon Fiber Tank, 100 cu. ft., 4500 psi tank.  Has anyone had experience with Omega tanks and if so, how would you rate them.  Thanks guys!

Thanks Bob.  As I said, I am new to all this so I'm doing my homework now to learn about the hobby.  When you say, the same as 88 cu ft tanks, are you saying the performance of a 100 cu ft tank is no more than an 88, so don't pay more for a 100 than you would an 88?  In terms of the brand Omega, are they a reliable product in the industry?

I have never seen any CF tanks of that size that are not a standard 1 hour SCBA tank as used by firefighters.... They are made by Drager and others, and every one I know of is 550 CI internal (water) volume.... If you use Boyle's law, at 4500 psi that works out to 99 CF.... The problem is, that once you go above about 3000 psi, the air molecules are so close together the pressure increases faster than the volume decreases (or you add more air to the tank).... and you have to allow for what is called the "VanDerWaals Correction".... Drager and the other tank manufacturers know this, and correctly rate their 550 CI water volume tanks at 88 CF.... If you crammed 100 CF into one, the pressure would be far above 4500 psi.... Some manufacturers are all about hype.... mine is bigger than yours....  ::)

AFAIK, they are ALL 88 CF, and the 45 min. SCBA tanks are 66 CF (not 75 CF).... If you want to make sure, ask the seller what the water volume is.... If he says 550 CI, you can take it to the bank that it's an 88 CF tank at 4500 psi.... If he doesn't know, ask who makes the tank, and check their website.... As far as the tanks go, they should all be the same.... as to the fill valve, hose, etc., I cannot comment, having never had an Omega tank....

Pay attention to when it was made.  Right now they are only good for 15 years, and then they are junk, they can't be re-certified.

Got it Bob.  Thanks for the education!  It's stuff I need to learn.
