Do you know, DEWALT DWFP55130 has got 3.0 SCFM (standard cubic feet per minute) which can deliver 90 PSI per minutes? Not only this, it has a built-in 2.5-gallon tank, and you can use this trim compressor up to 200 PSI. Although, it is not necessary to use maximum PSI always. Because you will finish your work before that.
