The Porter-Cable C7550 80 Gallon Oil-Lube Air Compressor offers powerful 5.4 (running) HP and 175 PSI air pressure to run just about any kind of air tool. Air delivery is solid at 90 PSI - 12.9 at 175 PSI SCFM--meaning, less downtime waiting for the compressor to recharge and more time actually using your air tools. The C7550 not only boasts industrial-grade performance, but it also has many features that increase its durability and lifespan. The two-stage, oil lubricated Twin-V cast iron pump greatly increases lifespan and overall reliability, and the pump contains automotive-style pistons, rings, and connecting rods that help to extend the lifespan of the C7550.
