What Is The Largest 4500PSI Carbon Fiber Tank Commonly Available ?
- Thread starter heavy-impact
- Start date
100 cubic feet is slightly larger than 700cc and I'm looking for a tank that is larger than 100 cubic feet.
100 cubic feet = 748 gallons
700cc is about 2 pints
My current tank is 74 cubic feet.

The largest most common size for fire department/scba tanks are 100 or 60 minute tanks. They are designed to be carried on firemen’’s back so size and weight is a major concern. I believe there are bigger CF tanks but I never seen them in surplus, those are very expensive new. Personally I don’t buy Chinese tanks for safety reasons.

Nitrogen rentals can fill whatever you have a zillion times. Kinda pricey and heavy. I think 6000 psi in a huge TANK. I considered the rental but instead just bought another 100 minute tank. Also considered buying a compressor BUT I don't like farting around with mechanical breakdowns and water trap filters. I leave that to my knowledgable filling store.

I wanted something like a 100cu/ft 90 minute but if there's something a little larger I'd get that. I have 3 pumps.

I have the carbondive 300 tank, but it is a hybrid steel / carbonfiber tank so it still have a weight to it, even if it is substantially lighter than my similar but 200 BAR 12 L steel tank
The carbondive 300 are 10.9 KG a all carbon from Alsafe also 12 L are 7.6 KG
Carbondive 300
Alsafe tank,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, ( OD in mm - Volume - lenght mm - weight KG - MAX pressure in PSI )
The 20 L alsafe carbon fiber bottle.
I do want to pick up a full carbon tank also in the 12 L size. ( you can actually get a 20 L tank too, and i might go for that )

Several guys in here have gotten tanks ( on gun tanks ) from alsafe and been very happy, i assume the same would be the case for a larger fill bottle.
Remember You can also get connectors so you can hook together 2 tanks, like divers some times do, but then transport are more problematic, but still doable if you are young and fit, for a old wrinkly and crusty guy like myself that is out of the question.

This is the largest carbon fiber tank at 12L that is portable and reasonably light for its size at 14.3 pounds. The steel hybrid tanks weigh 24 pounds empty. It also has a more common neck thread of M18*1.5 so that you can buy a fill yoke for it at many sites.

I.have a 90 min Scott 5500 psi. Its pretty sweet its the only one used I have ever seen for sale.. I think this is the biggest carbon fiber tank. I wanna go to 5500 psi and regulate with my aqua environment regulator to 4500 psi.so.I could upgrade my Texan and gain some fps

Just remember that the air in a 12 liter 300bar tank weighs some 4.7kg~10.3lbs

I think some of you folks are comparing apples to oranges. For clarity you should stick to vessel volume measurement only. The American ratings are very confusing. When stating 100 cu/ft, they mean 100 cu/ft of ambient air at some reference pressure. I don't know what that is without knowing the reference pressure. Also, you can not compare vessel size volume to minutes of use by a fireman. Most high pressure tanks use a wall thickness of about 1/2". A 12 liter bottle is about 28" tall and 24" in circumference or 7 5/8" in diameter and that's about the largest you could call portable. There are many larger bottles as well, but those are NOT portable

12 Liters = 732 cubic inches so the 20 L Alsafe tank is 1220 cubic inches.
The 20 liter i linked to above seem to be same measurements as the 12 L but taller so 85 CM VS the 57CM height of the 12 L bottle ( 33.4 inches VS the 22.4 inches for the 12 L bottle )
So yeah even if i am a taller guy with 6 foot 3 inches, then i would not go diving or smoke diving with that 20 L bottle on the back, but for carrying air around to shoot with,,,,,, hell yes i would.
Of course not something i would lug around in the forest, but going to the range or just hanging out with like minded people letting lead fly, i can not see a problem in that, and i am old and fragile and drive a car so small it is almost a micro, but i would still have room for that 20 L bottle just fine.
But yeah the great white are on the shelf in the US, Alsafe you would have to wait on shipping,,,,,, which as i recall from the people getting smaller tanks from them are not bad at all, and i am also not aware on the price for that bottle in China, but i think the guys that got smaller gun bottles got them at a reasonable price.
But ! The great white tank are by no means the biggest all carbon fiber tank around.
