I looked over my options and soon settled on a 20 gallon portable air compressor that would not only adequately run this particular tool, but would also serve my needs going forward. You never know what use you might find for such a great machine. Being able to power up and use tools with pressurized air is clean, efficient, powerful, and fun.
