Most of the small tankless compressors get HOT. even the ones with tanks get hot and are not really designed to be used long periods of time constantly. They do have a thermal protection that shut the compressor off if it gets too hot ( or at least most do) . Overheating can cause perm damage However the damage would not likly cause the moisture build up you are getting. You could try getting a small fan to blow across the compressor while in use. Unfortunatly these compressor are not meant for long uses. having a tank ( even a small one ) would greatly reduce wear and tear and heat build up
