Compressed air leak cost & payback
Compare up to three measured leaks, annual electricity waste and repair payback.

Formula & assumptions
Leak kW = flow (L/min) / 1000 × specific power (kW per m³/min). Annual energy = leak kW × pressurized hours. Annual savings = energy × tariff × reduction / 100. Payback (years) = repair cost / annual savings.
Use measured free-air flow and compressor specific power on the same reference basis. Blank optional leak fields count as zero. The network can leak outside production hours. This screening estimate assumes compressor electricity falls in proportion to removed flow; actual savings depend on compressor controls and unloaded power. Tariff and repair cost must use the same currency. No automatic tariff or exchange-rate assumptions.
