Hello I hope alls well. I am not super knowledgeable (no *s-word) with compressors. And I have a feeling I already know the answer. I just want to get anothers input. Say I were to build a gasoline engine powered compressor, since it's already continuously spinning the pump, the only difference being weither or not the unloader is open or closed.
Would tank size matter if I had a compressor that was supplying 4 times the recommended CFM of the largest tool? I understand that the stored air is there For the tool to draw apon. So your pump and motor aren't on all the time. But using an engine vs a motor it would be on the whole time. I'm not thinking tankless. I have a very small shop and my plan its to utilize my Ingersoll rand grate mate 20gallon as a compressor base/storage and have the engine on a platform built outside. My current set up takes up a bit too much room. 20gallon as a "wet tank" feeding through 2 3/4 lines into a 27 then into a 33 with water separators between each one.
