Air tools are an exercise in testosterone excess.

Mostly you'll use a home air compressor for filling tires, blowing things dry, and maybe for a nail gun.

You don't need a 220V compressor for his. You're going to finish off any tightening with a torque wrench anyway and you could easily tighten from the start with that same wrench. You're not "on the clock" for any home work.

Most folks that care about their cars don't deface the fasteners with impact wrenches.
