With the exception of filling tires everything you use compressed air for wants to and clean and dry.
An after cooler between the tank and the pump will do wonders for getting it dry.
Compressors are like politicians they make a lot of hot air.
Got to cool it to get it dry.
For regulator trap and filter good old ebay look for either 1/2 in or 3/4 in.
Need the filter to remove the oil.
