Air Tools - Air Consumption
Average Free Air consumption of some common air tools are indicated in the table below. The air consumption is based on commonly used working pressure of approximately 90 psi (620 kPa, 6.2 bar).
Note that the ratings are based on 25% load factor - or tools running 25% of the time. Full performance requires 4 times the volume.

- free air is actual quantity of compressed air converted back to the inlet conditions of the compressor. Note that the values are approximate. Free air consumption varies greatly between manufacturers. For more exact information always contact the equipment manufacturer.
- 1 psi (lb/in2) = 6,894.8 Pa (N/m2) = 6.895x10-3 N/mm2 = 6.895x10-2 bar
- 1 cfm (ft3/min) = 1.7 m3/h = 0.47 l/s
