Excellent choice. You'll have to put the plug on the power cord, insert the filter, and put oil in the compressor.
I also ran a drain line from the water separator to a plastic dish lined with paper towel and used duct tape to hold the line flat in the dish. I surrounded the line with paper towels so i have never had any splash or water to wipe off of the compressor.
I did use a few zip ties to hold the line place, because even opening the drain, even slowly could blow the line off of the drain spout.
So far the drain is working perfectly, no water to clean up.
Then you'll be filling your scba from 2800 to 4200 in 4 or 5 minutes.
I've also filled my two scuba tanks, 80 and a 117, both rated at 3442 psi, keep them filled and they take a few minutes also to top off.
Shoot all you want, you'll always have plenty of air in a few minutes.
