Pros
  • Over 10 CFM at 90 PSI runs impact wrenches, die grinders and spray guns
  • Much quieter than belt driven shop compressors of similar output
  • Oil free twin pumps need no oil changes
  • Short and wide enough to fit under a bench
Cons
  • Needs a 240 V circuit with a NEMA 6-15 outlet
  • A 1 year warranty is short for a $1,150 compressor
  • Sold only from the maker’s store, so there is no price competition
