Compressed air calculators

Compressor electricity cost, cost of leaks, receiver size, unit conversion: free tools to size and control your compressed air.

Compressor electricity costOver a compressor's life, electricity usually costs far more than the machine itself. Estimate what yours uses each year.Open the calculatorCost of compressed air leaksA leak barely makes a sound, but it makes the compressor run for nothing, all year long.

What are these calculators for?

Compressed air is one of the most expensive forms of energy in a workshop. A large part of its cost comes from the electricity consumed by the compressor, and a significant share of that air is often lost through leaks. These tools help you put a figure on these costs and size your installation before you buy.

  • Electricity cost: estimate what your compressor costs you per year according to its power, its running hours and your price per kWh.
  • Leak cost: measure the money lost through a leak according to its size and the network pressure.
  • Receiver size: find the receiver volume suited to your air flow and your consumption.
  • Converter: switch from one unit of air flow or pressure to another (m³/min, l/min, cfm, bar, psi).

How to use the results?

The results are estimates, calculated with the standard compressed air formulas. They give a reliable order of magnitude for comparing options. For final sizing, send us your results with your quote request: we check them against the actual specifications of the machines.
