If you are doing hi end lacquer jobs then get a Devilbiss dessicant(sp) dryer. If you have a big compressor that has an oil sump to lube the crank and pistons then you will need a coalessor in the line as well. Small oil free compressors still need a dryer if you want good results with oil based paints and lacquer.
There are two types of dryes systems pre coolers or intake refrigerators and output dessicaters.(sp)
If you don’t have a good quality HVLP and use a compressor for painting then get a dryer at leastIMHO.

In dentistry we had to use very tight tolerances to keep oil out of the lines. When you are painting a large project with a small compressor on a humid day the compressor is cycling while you are spraying and much of the moisture doesn’t have time to fully condense into the bottom of the tank and gets into the lines.
