Air Compressor Guides

Size a compressor to your air tools and keep it healthy: CFM, tank size, single- versus two-stage pumps, and routine maintenance.

The only compressor figure that matters is delivered airflow at 90 PSI, and the rest of the numbers on the box exist to distract you from it. These guides explain how to match a compressor to your air tools, what two-stage pumps really change, how to choose a stationary shop compressor and what to drain, oil and check so that it lasts for decades. The air compressor calculator estimates the airflow your tools need.
