Thread: how do you compare SCFM@90PSI to CFM@90PSI

    Default how do you compare SCFM@90PSI to CFM@90PSI

    I'm starting a basement project and have a nail gun that requires air CFM intake of 3-3.5CFM@90PSI. My current compressor has specifications that read SCFM@90 PSI= 2.1. How does that compare? The operating pressure for the nail gun is 70 to 120 PSI and the compressor has cut in pressure of 95 PSI and cut out presure of 125 PSI. Do I need a different compressor to operate the nail gun?

    Default I did a quick search

    I did a search, just to learn the difference between SCFM and CFM. I found a website that has a conversion calculator. It requires inputs such as temperature and relative humidity to do the math.

    Don't take my word for it because I'm totally out of my depth here, but it sure looks like the 2.1 scfm will not deliver the volume needed. Have you tried the nailer using your current compressor?

    It will probably fire the nail gun and drive the nails all the way in, the problem you will have is that it probably won't fire many nails in fast succession.
