Carbon fiber tank size comparison chart

For years I was tinkering but afraid to ask... what would be the Liter size for these my fireman tanks? Or in minutes or whatever?

I know the Acecare is 9L it is saying it on the sticker

Just to be a little pedantic.
Firemen work on trains, primarily very old trains. The fine ladies and gentlemen at your local FD are firefighters, not firemen. Most all the guys I know prefer firefighter. Cuz that is what they do!

I think a LOT more of them actually play with fire than you may realize. Fighting it is just a good cover and lets them get paid for playing with it lol. At least, that’s how the FFs I know are. All of ‘em are closet pyros, just without the psycho aspects of it. Well, aside from the crazy part about running INTO burning buildings… :ROFLMAO:
 
Yup, that is the part that will continue to garner my respect. Firefighters are awesome folks. I had a house fire in 2015, my home was built in 1926 and wood of course. My local firefighters were here within about 90 seconds of my wifes call, she could hear their sirens walking out the front door. Thanks to their rapid response my home was rebuilt and we lost very little, and nothing important. Most old homes burn to the ground, it cost 328 thou to fix it, but it is lots better now. My thanks always to the Longview Wa. firefighters.

Did a little shopping to learn that the 60 min firefighters air bottles are very hard to find, and when found are pricey. Lots of 30 min. bottles. Have any members ganged two of the 30 min bottles together? Seems to me that could be ideal, easy access to cheap air bottles, gang them at home for air storage, take one along for field and range use. If any members have done similar please post up pics of your setup. I'm considering the least costly and "cleanest" set up, wondering to stick with the CGA347 valves or swap the bottles over to airgun fill valves.
 
This is great thanks much for the clarification it will bring.

What about the 97cubic foot Great White he says it is 550 cu inches so that makes it an 88 cu ft 60 minute tank?
I own a bunch of bottles and have a great white. It's at least physically bigger in size than my 88. It seems to hold more based on known fill items. I don't want to drain them and measure fill times even on a dive compressor 😁. One day I will do so and dig this thread back up.

Try adding mine safety or mining to the search term too. I know there's some 60 minutes there.
 
All of the different units of measure used for carbon fiber tank sizes and fill capacities can be confusing. This comparison chart lists the commonly used carbon fiber tanks. The first two columns show interior volume of each tank size in liters and cubic inches. The third column is the air capacity for each tank size filled to 4500 psi. A few airgun dealers advertise that their tanks hold more air than competitor brands even though the internal capacity is identical. The two most common sized tanks sold are the 6.8 liter which actually holds 66 cubic feet of air at 4500 psi and the 9 liter tank that holds 88 cubic feet at 4500 psi. Their 6.8 liter and 9 liter tanks are sold to fire departments as 45 minute and 60 minute breathing air tanks.

The small 90 cubic inch tank is commonly sold for paintball but is also sold for PCPs. The 110 cubic inch tank is the most popular compact tank size. The 2 and 3 liter tank sizes are sold on Aliexpress and Ebay. The 4.5 liter size 30 minute tank is included for comparison but only available from Ebay or vendors which sell used fireman's tanks. The two most popular carbon fiber tanks sold by airgun dealers are the 414 cubic inch, 6.8 liter 45 minute fireman's tank, or the large 550 cubic inch, 9 liter 60 minute fireman's tank. The only sources of 12 liter tanks is from Aliexpress or some European dealers.

The chart below compares them by size and air capacity in ascending order of internal volume and air capacity at 4500 psi. This chart will help to compare the sizes and units of measure used on all of the popular carbon fiber tanks.
