88 cubic-foot carbon-fiber tank
by Harley Ayre
This air tank has revolutionized the operation of precharged pneumatics. When I was a boy I loved playing cowboys. Most of all, I loved shooting my sixgun, because I had a remarkable one. It never ran out of bullets. Reloading was for suckers, as far as I was concerned. If old Roy Rogers didn't have to do it, neither did I. An 88 cubic-foot carbon fiber air tank is a lot like that.
The old days of field target
Back when people were still winning matches with HW77s, a PCP was a curiosity at a field target match. Along with it came the mandatory 80 cu-ft scuba tank - that 39-lb. cold metal monster that had to accompany every PCP shooter in the field. You'd see them struggle to lug their tank to the firing line - and woe to the shooters at matches where the parking lot is separated from the FT course! Those tanks had no handles and were hard to move no matter what apparatus you brought.
Not many fills!
Once they got the tank into position, they began draining it into their gun. Since both scuba tank and airguns held the same 3,000 psi of pressure, it wasn't long before they no longer were able to fill their guns all the way. A 30-shot rifle became a 26-shot rifle, then a 24-shot, then, well you see where this is going. Those early shooters needed help from technology!
Enter, the hand pump
In 1996, the high-pressure hand pump came on the scene. Suddenly, there was an option. Instead of 39 lbs., you could carry just five, and you could fill all the way every time. Of course, the effort saved from carrying the scuba tank was more than repaid when it came time for a fill. There were guys who would smile and claim the pump was easy to use, but a lot of shooters didn't buy it. We were still waiting on technology.

Airhog's 88 cubic-foot carbon fiber air tank provides many times the refills of a scuba tank, yet it weighs half as much.
The dawning of the carbon-fiber tank
Airhog was an early pioneer in the use of the carbon-fiber air tanks for refilling PCPs. Van Jacobi recognized the incredible benefits of a tank that weighs half as much as a scuba tank but delivered nine times the number of full gun fills to 3,000 psi. That's right - NINE TIMES! Although the CF tank holds only eight cubic-feet more air than the standard aluminum scuba tank, most of that air is pressurized so high that it keeps on filling a precharged rifle to the limit long after the scuba tank has lost its initial pressure. Van was so impressed with the performance that he and his wife wrote an article for Airgun Illustrated magazine with test data that demonstrated the superiority of the CF tank.
Made for airgunners!
The CF tank was developed as a source of breathable air for rescue workers and firemen. Being relatively lightweight and holding as much air as it does, it's perfect for them. When Airhog started offering them to airgunners, the first thing they did was make a lightweight carrying handle for them. I can't tell you how many times I've carried my scuba tanks by their valve handles, which cannot be good. The Airhog CF tank carries like a light suitcase and even has two aluminum feet on which to stand in the field.
More innovations!
Then, Airhog introduced the microbore air hose. With an incredibly small inside diameter, a microbore hose wastes far less air when the line is bled after a fill. Since you no longer need to use the scuba valve handle and refill gauge as a carrying handle, Airhog incorporated them into a single streamlined unit. Carry your CF tank by the real handle and enjoy the lightweight, unitized gauge and valve handle.
Where do you get one filled?
Not all dive shops can fill to 4,500 psi. For many years, that kept people away from CF technology, but there's been a recent change. Paintball guns are now using air at this pressure and higher, so many paintball shops can now fill these tanks. Of course, if you have an "in" at the local fire station, you'll have no problem getting your tank filled. If you don't have that advantage, check out your local paintball shop.
It's not cheap
You do pay for all the benefits you get with a carbon-fiber tank. For some, the price is a complete turn-off. For those who have been wanting this convenience, the carbon-fiber air tank is worth every penny.
