In an unmanaged plant, a third of the compressed air never reaches a tool. The compressor pays for it anyway. Here is where it goes, and how to get it back.
Couplers and disconnects
The average worn quick coupler leaks enough air to cost a three-digit sum a year. Walk the line on a quiet weekend — the hiss map is your repair list.
Condensate drains stuck open
A timer drain that jams open is a permanent leak the size of a nozzle. Zero-loss drains pay for themselves in months, not years.
The pressure band nobody questioned
Plants creep pressure up to mask leaks, then leak more because pressure is up. Fix the leaks first, then walk the set point down 0.5 bar at a time until a tool complains.
Make it routine
An ultrasonic survey twice a year, drains on the maintenance plan, and a pressure log on the wall: the boring routine that keeps 30% of your electricity where it belongs.
