Many people have tried this and failed. Air Pressure will equalize. You can't force it back into the tank the same way. There have been many many many threads on here about this topic.
Sure there are ways to help rebuild the air pressure, but really, don't you think that if there was a way of doing this people would be doing it and selling the idea???
You can't recycle 100% of it, it's basically impossible to do without a very complex system that really just wouldn't make it worth it.
If you have some kick ass compressors, then what's the point really.
