Air Compressor Cfm Requirements

This compressor has plenty of power for the impact wrench.

Air compressor cfm requirements.

Step 1 determine your air requirements. Step 2 once all the air requirements have been determined total the cfm needed for the air compressor. Use the chart below to determine your average cfm requirements per tool or check with the manufacturer. Scfm makes it easier to match cfm requirements by using the apples to apples approach most manufacturers will measure their cubic feet per minute flows in a standardized environment so when you see a cfm rating on an air tool or compressor assume it is scfm.

In this example. Every air tool has a recommended cfm requirement that s set by the manufacturer. Cfm represents the volume of air that is produced by your air compressor or required by your air tool. Psi refers to pounds per square inch.

To determine what cfm rating you ll need in an air compressor take the highest cfm rating of your current air tools or tools you plan on purchasing and multiple that by 1 5. Cfm cubic feet per minute refers to the volume of air that can be moved in one minute. An impact wrench is an air tool that draws a lot of air which is why you ll need an air compressor with a rather medium sized tank and plenty of cfm power. There are several considerations when determining the necessary cfm for an application including the compressor cfm the blaster cfm and the size of the nozzle.

In the example below we are sizing the compressor for a typical auto body shop. It features a powerful motor to supply your air tools efficiently. Sandblasting requires air compression the more cfm the better.
