Compressor electricity cost

How this is calculated

The calculation multiplies motor power by the hours the compressor runs. Loaded, it produces air and draws full power. Unloaded, a screw compressor idles and still draws roughly a quarter of its power (a common order of magnitude); a piston compressor stops. The result is an estimate: motor efficiency, set pressure and the machine's condition all change real consumption.

To cut the bill: fix leaks, set pressure to what is actually needed, switch the compressor off outside working hours, and choose a machine matched to real demand.

How to reduce the bill?

• Track down leaks: this is often the quickest gain, because the compressor no longer runs to feed them.
• Lower the pressure to what is strictly necessary: every extra bar increases consumption.
• Shut off the air in the network outside working hours.
• Choose the right machine: an oversized compressor runs off-load for long periods; a variable speed compressor adapts its speed to demand.
