📘 Definitions
Rated CFM
Free air delivery per compressor nameplate at ISO 1217 reference conditions (20 °C, 1 atm, 0% RH).
Load Factor
Average percentage of time the compressor operates at full load. Industry typical range: 60–90%.
Operating Hours
Actual hours per day the unit runs under load. Excludes idle, standby, or maintenance periods.
Daily Air Volume
Total compressed air generated per day in standard cubic feet, suitable for energy audits and planning.
Disclaimer: Results are estimates based on rated capacity and average load factor. Real-world air consumption may vary due to system efficiency losses, leak rates, downstream demand fluctuations, and operating conditions. For peak demand analysis or detailed system sizing, comprehensive flow profiling is recommended.
