My compressor has an auto drain on a timer. I made a copper air cooler with drain valves. Then that goes into an air dryer. Then a one-gallon desiccant dryer and a motor guard filter.
3/4" rapid Air connecting it all together.
The dryer the air the better the cut and the longer consumables last.
I may add a air cooler at the compressor after the pump before it enters the compressor. I am going to wait to see if I think it is needed.
