Hi Vladan, I have a small cabinet that I use, and it is powered by a: 5.5 HP (peak) 1.7 HP (running) 9.9 CFM 150 PSI max 32 Gallon compressor. It has plenty of pressure to run my system, but the capacity is too small. I would recommend at least a 60 Gallon compressor. The problem with any smaller compressor is that the motor has to run too much - gets pretty hot. I used to use a 5 gal compressor and it worked too, but literally never stopped running. The 32 gets a break once in while (for a minute or two only) then starts back up. I would much prefer to have a system that is not constantly running. As I said, smaller units will work, but you have to take more breaks. With my 5 gallon, while cleaning keysticks, I could do about 3 sticks, wait for the pressure to build (wait longer if I wanted to let the motor rest), and go again. VERY VERY tedious. With the 32 Gal. I can do a set straight through, but often take a break halfway to let the motor rest and cool. 60 gallons will come next, after a few other toys ;-] Best, William R.
