The pneumatic tools are better when quality. If cheap, they are worse that the electric ones. You should look for tools that do Not need to be oiled daily. They are the good ones. You will need to fashion also air drier after the compressor.

Nailers do not have a demand for a quality compressor. Not so with rotating tools. I would say 150L is a minimum for such tools.

The game changer tool, that could be used with a compressor is an orbital sander. But a proper one, not the cheap crap. I have the most expensive model of Chicago Pneumatic/very expensive/ and Oh boy... It changed the way i am finishing wood. Its an incredible tool.
