For very shallow work that isn't too stressful (boat cleaning), I tend to consume about 0.8CF/min. 1 CF is just shy of 30 normal liters. Surfing around the web, I found this little $50 unit who's spec's look marginally acceptable for that low stress task. Wagan Dynamite Power Air Compressor Wagan Tools WC2050. Adding a small air tank to the system might improve capacity enough to make it work a little better.

This $90 2-cylinder unit may be a bit better, but no volume spec's are listed, so it's hard to compare http://www.aircompressorsdirect.com/...sor/p7634.html

Most second stage regulators will want to see something in the 100+ psi range for feed pressure. Adjustments can usually be made to the second stage to make them open more easily. Most second stages are an unbalanced design. This means that if you are not running off of a regulated pressure, the mouthpiece will tend to alternate between free flowing & breathing hard, as pressures in the line vary.

As you get deeper, you will need the same volume of air at a higher pressure. This means that as you go deeper, you will need a higher capacity compressor.

This is all just semi-educated guess work from calculating the posted numbers a bit on the thin side. This is not something that I have tested, nor necessarily endorse.
