Ok, what’s the skinny on air compressors. I know that’s such a newbie question, but oh well. From everything i read, you all recommend buying the biggest, most powerful (CFM) that I can afford. Fine, i trust you guys, but why? What does all that CFM really get me? I’m sorry that I don’t understand it. I’m assuming that more CFM means you can blast things faster, but I thought that the air pressure was what determined the rate at which the media worked.
