Table 1 Compliance Tip: You need 25 CFM for every 1″ of grinder wheel. A 5″ grinder needs 125 CFM minimum, while a 9″ grinder needs 225 CFM. However, it's about the wheel size, not max wheel size. If you use a 7″ wheel on a 9″ grinder, you only need 175 CFM. In most cases, you need to add a dust shroud to the grinder.
