Always check with tool manufacturers for actual air consumption of tools being used. The above is based on averages and should not be
considered accurate for any particular make of tool.
Above tools are rated based upon typical “on-load” performance characteristics.
For other values, adjust the C.F. air consumption on a proportional basis.
The cubic feet (C.F.) air consumption for 1 minute may also be expressed as air consumption in cubic feet per minute (C.F.M.)
