If you are just using burst type tools (nailers) in a non-production environment, most compressors will be fine. If you want to use continuous flow tools such as grinders, sanders, or sprayers, then you need to worry about the required cfm (cubic ft/min) of the tool compared to the compressor. The PC compressor linked on Amazon will do about 3.7cfm @40psi. A framing nailer, for instance, requires about 2.2cfm @90psi. A larger tank will allow a smaller compressor to run a larger device longer, but still not continuous.
