As I've mentioned in earlier posts, I'm looking to buy a small compressor for misc home use. I want the smallest usable unit I can get.
Besides low demand tasks, I would also like to occasionally use an impact wrench for a seasonal tire rotation and possibly a die grinder for stripping rust on a wrought iron railings. I've seen both tools rated at around 4cfm @ 90psi.
I visited my local Lowes store and saw a DeWalt/Emglo 4 gal machine rated at 4.1cfm @ 90psi. When I mentioned my intended uses to the sales clerk, he laughed. He said I need *at least* a 15 gal tank to run either tool.
What sort of intermittent use, if any, would a 4 gal unit provide? I don't need Mr Goodwrench levels of performance. I'm just a guy in the driveway doing 2 wheels at a time.
Do I truly need 15 gal+ before even considering using an impact wrench or grinder?
Thanks
