The hidden line item. Compressed air is one of the largest electricity costs in a plant — and a share of it leaks away every hour of every shift, already paid for, before it ever reaches production. For finance and operations leaders, that is not a maintenance issue. It is a recurring, recoverable line on the power bill.
Air that leaks out of the system was still generated by your compressors, dried, treated and pressurised, using electricity you already bought. It simply escaped before doing any productive work. The reason the cost survives, year after year, is not negligence: at operating pressure the escaping air is effectively silent against plant noise. It never appears on a maintenance report — only on the electricity bill.
An ISO 11011 audit makes that invisible cost visible — and decision-ready.
Where the money is actually leaking
- Connections that pass inspection — tight-looking fittings leaking through the thread or seal.
- Drains stuck open — a condensate drain failing part-open vents purchased air continuously.
- Worn regulators and filters — hundreds of points of use, each leaking a little.
- Losses behind panels and guards — what can’t be seen never gets fixed.
- The compressor room — the highest-pressure zone, where leaks cost the most.
What you actually get
Every leak is located, measured, converted into an annual cost, and ranked by repair priority. The deliverable is a costed action list — not “you have leaks,” but exactly where the money is going, what each fix returns, and the order to do them in. The top few fixes typically recover the audit within two to four months; the rest is margin.
The business case, not the engineering case
- Lower energy cost with no capital outlay.
- Higher efficiency — stable pressure, no round-the-clock bleeds, less energy per unit of output.
- Lower carbon (Scope 2) — measured and verifiable for buyers, lenders and regulators.
- Right cost allocation — apportion air cost to the products that consume it.
- Capex you can defer — recover installed capacity before buying more.
And none of it requires a shutdown — the survey is done with the plant running.
