a booster is an air compressor that also runs on compressed air. it needs a ~120 psi shop air supply to run it, then usually ~1000 psi to feed the input side, and then it outputs higher psi.. in our case 3000, or 4500. it fills a large ram with 120 psi air to push down on a very small chamber of 1000 psi air to compress it up to 4500. it does this repeatedly until the 4500 psi side reaches full pressure. (in this case, when your paintball tank is full)
what this allows you to do is continue filling paintball tanks to 4500 psi even when your stored air is lower pressure than that.
