Kobalt Oil-free Compressor spits water

I have that same compressor and am very happy with it.I do however drain it after every use.I don't see too much condensation accumulating. Maybe just location,temperture ,and relative humidity.
I just noticed you mentioned " Lengthy fill up" Mine charges up fast .You might want to check all the fittings .After I picked up mine I read a review where someone mentioned several loose items I did a nut and bolt of the entire thing and found a few items needed tightening.
It's been my experience working with compressors in my work that the slightest leak will significantly alter the fill time , create excessive condensation. And shorten the life of the unit.Further more the pump itself could be defective accounting for the lengthy fill time and excess moisture.
