How is the Average SCFM for an air tool calculated? Is there a formula?
James, not to my knowledge.
It’s like asking if there is an average motor size in all the cars in the world.
Each manufacturer of air tools builds their tools to provide a certain amount of force to do the job that tool is supposed to do.
Another manufacturer of that same type of tool will make a DIY model with less force and lower cost components.
Another manufacturer will make the same type of tool, but in industrial strength size.
Each will use different levels of flow.
On the pages on this site is more information about air flow, CFM and compressor sizing
The pages provide a guide of some air tool usage as well.
Yet, the only thing you can do for sure is to pick the tool, read the manual and or specification plate, and see what that air tool requires in flow and pressure.
Then, if you give it that, the tool will work properly. If you don’t, it’s like feeding the carb (my, that does date me doesn’t it) with too little fuel when you step on the gas in the car. The car will not run properly.
Neither will your air tool.
