About Carbon Fiber Tanks
Carbon fiber tanks are relatively new to the wind energy industry. However, they have long been used in the paintball, fire fighting and medical fields. The tanks are made out of composite materials developed by NASA for use in space exploration. This "space age" technology makes the tanks lightweight, strong and capable of accepting charging pressures of 4500 psi. As a result, they are just the thing to take up into the nacelle of a wind turbine or carried into a burning building. Why buy a Carbon Fiber Tank? What are its Advantages? Carbon fiber cylinders enjoy several advantages over the more commonly used steel tanks.
Carbon fiber tanks can be filled to 4500 psi while most scuba tanks are only rated to 3000 psi. This higher pressure capability not only allows the carbon fiber tank to hold more useable air, but it also enables it to supply more fully-rated fills versus a regular scuba tank.
• We compared an 88 cu. ft. carbon fiber tank to a regular scuba tank and found it supplied nine times the full fills of a scuba tank. (See Airgun Illustrated's May 2003 issue to read about our test.)
2).Carbon fiber tanks are available in several different sizes. The large 88 cu. ft. tank is 21 & 1/2" tall with an outer diameter of 6.9" in diameter. The small 17 cu. ft. tank is only 15.2" high and 3.8" in diameter.
3). Carbon fiber tanks weigh about one-third as much as a corresponding steel scuba tank. An empty 88 cu. ft. CF tank weighs about 12 & 1/2 pounds. That is quite a weight reduction when compared to a 35-40 pound scuba tank.
4). Carbon fiber tanks are easier to transport. Given their compact size and their lower weight, handling a carbon fiber tank is considerably easier than a steel tank.
