Compressed air is your most expensive utility. Almost nobody meters it.
Compressed air typically takes 10–30% of a plant's electricity bill, and a fifth to a third of it leaks away unnoticed. MachineWise monitors every compressor continuously — specific power, load factor, leak load, airend health — and prices each loss in rupees.
Up from 0.178 in March at the same 7.2 bar: check the intake filter and belt before suspecting the airend.
Four losses, all invisible without measurement.
The night test nobody runs
With production stopped, anything the compressor still delivers is leaking. We measure loaded running during idle periods automatically, every week, and turn it into a leak load percentage and a rupee figure — instead of an annual audit that never gets scheduled.
Load / unload churn
A fixed-speed compressor unloading forty times an hour burns power producing nothing and wears the airend. Cycle counts and load factor expose oversized machines and badly set pressure bands.
Set at 8.5 bar because someone once did
Pressure bands drift upward over years as people chase a symptom. Continuous pressure logging against actual demand shows how much headroom you are paying for.
Every compressor, every second.
Connected by the MachineWise team, with a smart energy meter and pressure sensing on each compressor — no shutdown to install.

The compressor tells you first — if something is listening.
Because a compressor runs continuously at near-constant load, it produces the cleanest training data in the plant. That makes it the single best candidate for machine-learning condition monitoring, and usually the first machine where predictive maintenance proves itself.
Airend bearing wear
Defect frequencies rising in the envelope spectrum weeks before discharge temperature moves.
Valve failure on recips
Suction and discharge valve leakage shows as a change in the current signature and in cycle timing.
Efficiency decay
Specific power creeping up at constant pressure means the airend is wearing, the filter is loading, or the belt is slipping.
Cooling problems
Approach temperature drift on the aftercooler predicts high-temperature trips before they stop the plant.
Put one compressor on a meter this week.
Tell us your compressor sizes and running hours. We will monitor one compressor free and show its kW per CFM and weekly leak load in rupees.
Straight answers.
How is compressed-air energy measured?
How are compressed air leaks found?
What does a rising kW per CFM mean?
How much energy does lowering the pressure save?
Put one compressor on MachineWise, free, for thirty days.
We will report your specific power, load factor, estimated leak load and airend health — and price every one of them in rupees before you decide anything.
