Hey all,I've been thinking about CF scba tanks vs alu/steel scuba dive tanks. I like the idea of fiber wrapped tanks being lighter and easier to move- my new 3200 PSI aluminum tank is a bit heavy. But, that got me thinking about comparable CF vs volume. How big are 45 minute CF scba tanks? What are the dimesions of the CF tank, and how do they compare to an 80CF scuba tank? I am wondering because my compressor goes to 3200PSI, probably tops out at 3500PSI from what I've seen. Are the 45 min CF tanks similar in size? My worry is that I may pick up a Carbon fiber tank eventually, but if I only fill to 3200 or 3500, what CF will the tank actually be holding vs a regular 80CF scuba tank? My current tank is an 80CF, 8" x 25", but rated at 3200PSI vs 3k, it's actually about a 92CF tank. What would a 4500PSI tank hold filled to 3200?-Michael
