Calculation reference

What this tool checks.

Duty cycle is a capacity screen. Final compressor review should include receiver size, pressure band, leaks, dryer loss, simultaneity, and compressor control type.

Inputs

  • Average air demand
  • Compressor FAD capacity
  • Reserve allowance
  • Target duty limit

Outputs

  • Base duty cycle
  • Duty with reserve
  • Capacity margin
  • Status note

Engineering guide

Use the result with the right context.

Calculate compressor duty cycle calculator from application data and interpret the result for preliminary pneumatic engineering review.

Calculation workflow
  1. Enter the known application values, including Average air demand, Compressor FAD capacity, Reserve allowance.

  2. Run the calculation using one consistent set of units and reference conditions.

  3. Review Base duty cycle, Duty with reserve, Capacity margin, then compare the result with the component datasheet and application margin.

Assumptions and limits
  • Keep standard, free-air, and actual compressed-volume reference states consistent throughout the calculation.

  • Confirm compressor, dryer, filter, receiver, pipework, ambient, and operating schedules with measured plant data.

How the Compressor Duty Cycle Calculator works

This calculator turns Average air demand, Compressor FAD capacity, Reserve allowance into Base duty cycle, Duty with reserve, Capacity margin. The governing relationship remains visible in the dedicated formula area so the result can be checked against a worksheet, supplier data, or measured machine values.

How to interpret the result

Use the output as a transparent first-pass engineering estimate, not an automatic product approval. Compare the calculated value with available catalog ratings, transient conditions, installation losses, service environment, and a safety margin appropriate to the machine risk.

Limits and verification

Keep standard, free-air, and actual compressed-volume reference states consistent throughout the calculation. Confirm compressor, dryer, filter, receiver, pipework, ambient, and operating schedules with measured plant data. The final selection remains subject to the actual component datasheet, applicable standards, and validation on the installed system.

FAQ

Common review questions.

01Tool noteWhat is a good compressor duty cycle?

It depends on compressor type and controls. Many preliminary reviews keep margin below the entered target rather than running continuously at full capacity.

02Tool noteShould leaks be included in average demand?

Yes. Include measured or estimated leakage, dryer purge, blow-off, vacuum generators, and simultaneous actuator demand for a realistic review.

03Tool noteWhat should I verify after using the Compressor Duty Cycle Calculator?

Check the entered units and reference conditions, then compare the calculated outputs with manufacturer ratings, application safety margins, transient loads, installation losses, and measured machine performance.
