Formula and assumptions

P (kW) = QFAD (L/min)/1000 × Pspecific [kW/(m³/min)]; E (kWh) = P × t (h); C = E × p

Flow is measured FAD, not compressed pipe volume. Specific power must include system electrical input per FAD. Hours are pressurized hours. Gross energy model; actual savings depend on compressor controls.

STEP BY STEP

How to use compressed air leak cost calculator

  1. Check the input units and assumptions.
  2. Review the result and example.

IN PRACTICE

Example

100 L/min; 7 kW/(m³/min); 8000 h; 0.15/kWh → 0.7 kW; 5600 kWh; 840.

GOOD TO KNOW

How is this result calculated?

Leak power (kW) = FAD leak (L/min)/1000 × specific power [kW/(m³/min)]; energy = power × pressurized hours; annual cost = energy × price/kWh. Flow is measured FAD, not compressed pipe volume. Specific power must include system electrical input per FAD. Hours are pressurized hours. Gross energy model; actual savings depend on compressor controls.
