New Compressor questions

Look at the motor, it will state the run time on it. Mine is 5hp rated continuous meaning it can run without fear of over loading itself. It's on a 60 gallon tank and when running a da or something for extended time I still wait here and there mainly so the air doesn't get moisture in it because the da will tap out the tank and then its running off just the motor. Proper lines, filter and water trap all go a long way but if your pushing an under rated compressor for the job don't expect a good outcome, a lot of waiting, slow process, moisture in your tools, etc.
