Sometimes this old brain just doesn't understand things. Let me explain what I think I know and then chime in with what is real.
The air you use to run air tools comes directly from the holding tank via pressure valves/gauges. If a compressor is rated at say, 7[EMAIL="7CFM@40PSI/4.9CFM@90PSI"]CFM@40PSI/4.9CFM@90PSI/4.3CFM@115PSI[/EMAIL], that is the rating of the compressor pump and how fast and at what pressure it fills the tank. Thus if I have an air compressor that came with the first rating and find a pump/motor that is rated at say 7.76CFM@115PSI and put this pump/motor on my tank, would my tank output still be at what it is now or would it go to the higher spec. Remember, I have not changed the valves/gauges on the output side of the tank. In other words, is the rating of an air compressor related to the pump/motor and how fast it fills the tank or to the effeciency of how well you get the air out of the tank to the tool. To me the two are not directly related. (I do realize that if you take more from the tank than can be replaced in the same amount of time, then the compressor will run behind and run continous). All this being the case why can one not run high CFM tools from a holding tank, just in shorter spurts as the pump tries to catch up?
Confused!!!!!
