The air temp is hot coming out of the compressor and the air isn’t cooling before passing through the water separator. My guess is the separator is attached right to the air tank? I run a short hose from a ball valve on my tank down to a bucket and attach to a coiled tube in the bucket, from the bucket/coiled tube the hose comes up to a series of 5 water separators and filters. Before I spray, I drain all filters and air tank. Then I fill the bucket with ice and top off with water making a slurry. The majority of my moisture is trapped in the first water separator so I leave the drain cracked a hair because I have filled it this time of year. I still run a disposable at the gun and toss each day I spray more if I spray a large job.Why all the moisture? Condensation happens between hot and cold and it is certainly not cold.
Are you sure you got all the moisture out? Something not right with the amount of water your getting.
