Kobalt Oil-free Compressor spits water

Another reason for water, that I found, is how long does the compressor run? If it isn't big enough, CFM's, it runs constantly trying to keep the tank filled to the shut off point. I tried using a air operated sander......will not work. I use the hose up, then down with a trap after. Also have a dessicant trap right before my spray gun, and I try not to hold it open for very long. This is what works for me. Oh, and I don't have 220 in my garage, only 110. 220 compressor would most likely provide the CFM's needed.
