Use the Required Compressor CFM Calculator to calculate required free-air delivery from point-of-use demands. The calculator uses Machine/tool demand, Duty cycle, Leakage allowance and Reserve and reports required cfm/fad.
Read the result in the context of the selected units and pressure basis. For this tool, the primary outputs are required cfm/fad. Change one input at a time when comparing scenarios so the effect of each variable remains clear.
PneumaForge applies this verified method: Σ demand × simultaneity/duty + leakage/reserve. The functional engine is shared with related tools in the compressor-demand family, while this page solves the specific intent represented by required compressor CFM calculator.
Σ demand × simultaneity/duty + leakage/reserveReproducible example: start with the calculator's default values (Machine/tool demand = 2000; Duty cycle = 50; Leakage allowance = 10; Reserve = 15) and calculate the result. Then change the variable most relevant to your application and compare the new required cfm/fad against the baseline.
Duty/simultaneity/reserve are explicit assumptions; no hidden diversity factor.
It is designed to calculate required free-air delivery from point-of-use demands. The reported outputs are required cfm/fad.
The calculator uses Machine/tool demand, Duty cycle, Leakage allowance and Reserve. Only use values that represent the same operating condition or design case.
The calculation follows: Σ demand × simultaneity/duty + leakage/reserve. The page also states the assumptions that define where the method is valid.
Duty/simultaneity/reserve are explicit assumptions; no hidden diversity factor.
Yes. PneumaForge converts supported units through canonical engineering units. For compressed-air reference flows and pressure bases, the reference pressure and temperature must also remain consistent.
