Compressed Air Leak Survey Before Buying a New Compressor
Low pressure at the tool does not always mean the plant needs a larger compressor. Leaks, open drains, old hoses, and weak pipe joints can waste air before it reaches production. A simple leak survey protects the buyer from choosing equipment around a hidden problem.
Quick answer
Inspect drains, couplings, hoses, filters, tank fittings, pipe joints, tool drops, and unused branch lines. Record leak location, severity, repair owner, and whether the pressure complaint remains after obvious leaks are corrected.
Start where leaks are easy to hear
Walk the system during a quiet period. Listen near drains, flexible hoses, quick couplers, filter bowls, tank connections, and old branch lines. Mark each point on a simple layout so the buyer can plan repairs.
Do not ignore unused lines
Many plants keep old drops or unused hoses connected. These points can leak for months because no operator owns them. Ask whether any branch can be isolated before the compressor selection is finalized.
Connect the survey to sizing
If a pressure complaint improves after leaks are corrected, the selection discussion may change. If the complaint remains, the distributor still has better data for reviewing air demand, piping, and receiver tank behavior.
Make the record easy to repeat
Use the same survey sheet before and after repair. A repeatable record helps the buyer see whether the system condition changed, without relying on memory or a casual verbal update.
FAQ
Can leaks make a compressor look too small?
Yes. Air loss in piping, drains, hoses, and couplings can reduce pressure at the point of use even when the compressor is operating normally.
Should leak repair happen before equipment selection?
Obvious leaks should be recorded and reviewed before final selection, because they can change the demand picture.
