Vehicle Onboard Air Compressor to run power tools!

[KickStart]

This is interesting.
I haven't read any further yet, but I don't recall these compressors have an oil sump. I've used earlier piston compressors that did, and they were nearly plug & play and bombproof, but they needed to sit upright and were a tough fit under the hood of some vehicles. A/C systems were oiled through the system and that's too much oil for air tools. Of course, technology may have addressed most of the oiling. Maye the Sanden radial is designed to run without so much oil. They were new when I quit playing.
I'm way out of touch with what's been going on this front, and have forgotten anything I may have known. It's time to start studying.
