I'm not sure why you would need a compressor. Don't the barrels dry nearly instantly when you pull them from the boil?

What little water I might find pooled in a dovetail or something like that I wipe down with a paper towel soaked in alcohol. I do that only to prevent any mineral deposit as the water dries (which it would in about 20-30 seconds if not less).
