I'm getting ready to dive into a first set of air tools, and I noticed that most 1/2" impact wrenches say they consume around 6 CFM @ 90 PSI. There's a 21 gallon CentralPneumatic compressor that provides 4.7 CFM @ 90 PSI. Does that mean you won't get the full potential of the tool if you use it with this compressor? Or is this totally different and not something to worry about? Trying to decide between the 21 gallon and the 29 gallon model (for twice as much, unfortunately). Any suggestions for compressors to get that work on 120V (for fairly cheap)?
