No it would not. You know it is 2216 because it is stamped in the Aluminum (which is Scuba). Pop on over to the fill em up section and look around perhaps.
Not only a SCUBA, our Scott Air Packs (SCBA's) at work use these, dang it. Be sweet if they were 4500 CF though. Pretty common in the private sector (Oil Co's) anyway.
The setup works great! Now that I have my own Yong Heng compressor no more trips to the dive shop to top it off. Guy was charging me $20 for a top off!
