Use the Compressor Load/Unload Cycle Calculator to calculate load fraction and cycles from observed timings. The calculator uses Load time, Unload time and Observation duration and reports load %; unload %; cycles/hour.
Read the result in the context of the selected units and pressure basis. For this tool, the primary outputs are load %; unload %; cycles/hour. Change one input at a time when comparing scenarios so the effect of each variable remains clear.
PneumaForge applies this verified method: Time fractions and cycle count. The functional engine is shared with related tools in the duty-cycle family, while this page solves the specific intent represented by compressor load unload calculator.
Time fractions and cycle countReproducible example: start with the calculator's default values (Load time = 20; Unload time = 40; Observation duration = 60) and calculate the result. Then change the variable most relevant to your application and compare the new load %; unload %; cycles/hour against the baseline.
Observation time must be >0. Separate loaded, unloaded and off states when provided.
It is designed to calculate load fraction and cycles from observed timings. The reported outputs are load %; unload %; cycles/hour.
The calculator uses Load time, Unload time and Observation duration. Only use values that represent the same operating condition or design case.
The calculation follows: Time fractions and cycle count. The page also states the assumptions that define where the method is valid.
Observation time must be >0. Separate loaded, unloaded and off states when provided.
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.
