LP80s has already been said. Awesome sidemount tank!!!!! Love the short length versus lp85s. Another plus is they function well as a stage if you want more gas than an AL80. They aren't real heavy with a cave fill as a stage,but provide lots of gas.

they look like LP66 to me, I have 4 of those around. Pumped to 3500 and they are nice...I use them for rec diving mostly

That was my guess. The length would help.Originally Posted by cerich
I have a set just like them, Faber 80s set up for sidemount, born 1997, 2015 Hydro and VIP, just had them galvanized so they look gooid. I'm using 85s, 108s, and 120s for sidemount so don't need the 80s. Bill

Tank height is about 24.5 inches still think they are LP 80s? Or LP 66?

LP66s are only 21", LP80s are 24" (not including valve)
check on the fare side of the main writing on the tank and see if there are some letters and numbers
they are out to hydro now... perhaps Faber will give me an official answer before they come back. I'm leaning towards the LP80... or at least hoping that's what they are. I didn't get to measure them myself, as I had already dropped them off, but I called the guy at the shop and asked him to measure.. he said "uh.. .they are 24 or 25" from the floor to the top of the neck".
Still a mystery to me...
I got a response from Faber... they simply replied:
"The cylinder is a 11.9 liter, diameter 184 mm, pressure 2400 psi"
Well, I pretty much failed at math so of course I replied to ask... "how many cubic feet of breathing gas @2400psi?" I figured this is his profession so I should get a pretty straight forward answer. His reply,
"Cubic foot capacities for scuba cylinders are nominal and actual volume depends on settled pressure, temperature and specific gas being filled.
Based on the liter size and working pressure of 2400 PSI it would be approximately 72 CF breathing air. "
So I'm kinda still stumped. somebody help out the blonde guy please. These are 72's?

I think those that guessed 66 are correct.
This might help...
12 litre = 0.424 cf
2250psi tank... 64 cf
3000psi tank... 86 cf
3300psi tank... 94 cf
3500psi tank... 100cf
