You have your air compressor and powder coating gun and you are ready to start powder coating? Not so fast, make sure you read this article first. When powder coating or sandblasting, you need clean, dry air. More than just compressed air comes out of the outlet of your air compressor. Water, dirt, and oil will also be included in this compressed air. It is very important that you treat your compressed air and remove these contaminants when using your air compressor for powder coating. The same information I am about to provide also applies to auto painting, compressed air machinery, or even just using common air tools. Any tool that connects to your air compressor will appreciate a clean air supply. Read this article: How to Choose an Air Compressor if you haven't purchased an air compressor yet.
