How much air do I need?

Air Tool Consumption Guide

It is always best to check the specifications with your tool manufacturer, but if this information is not available, our air tool consumption guide will provide a rough guideline.

A common question we get revolves around how much air a particular tool uses. Whether it’s an impact gun, grinder or breaker, there are various ranges of air consumption each of these tools use. We have put together an Air Tool Consumption Guide that includes common air tools in various sizes.

Please note this is only a guide. The tool manufacturer will have exact specifications for each model.
