Many points of view and understandable. There has been a generation that has known and lived with these limited smaller air compressors. I guess it is just a case of what you want to do both presently and in the future.


As for a test on a used compressor. The most important one is the time to fill the empty tank from empty. If it is rated at say nine cubic feed per minute output. It should fill the 20 gallon tank in just a little more than two minutes till shut down.
