*** Different companies will use different assumptions of how long the air tool will be used within the space of a minute. Therefore the average air consumption value stated in the table is only useful when comparing tools from the same company.

Airflow Calculator

NB: The calculator has a ‘safety factor’ of 1.2x cfm incorporated to ensure the right compressor is chosen. It also also factors in the variability in duty cycle assumptions that different companies use when calculating the average cfm rating for their air impact wrench.
