Sizing a shop compressor

Add up the CFM of the tools you'll run at the same time, then add a 30% margin. Our CFM calculator does the math. Then pick the tank: 20 gallons for intermittent tools, 60–80 gallons for continuous sanding, grinding or painting.

Heavy duty means duty cycle

"Heavy duty" should mean the compressor can run a large share of the time without overheating. Oil-lubricated two-stage pumps running at low RPM are built for that; small oil-free units often list a 50–70% duty cycle.

Frequently asked questions

What size air compressor do I need for a home shop?

For nailers, inflation and occasional impact work, a 10–20 gallon compressor with about 5 CFM at 90 PSI. For sanding, grinding or painting, a 60-gallon 240V compressor with 10+ CFM at 90 PSI.

Where should a shop compressor go?

On a level floor with airflow around it, ideally in a separate room or enclosure to cut noise, with hard lines to drops where you work. Leave access to the drain valve.
