Compressed Air Leak Detection

Compressed air leak detection is the systematic identification, recording, repair, and verification of unintended air losses from a compressed-air system.

What this term means in maintenance

Compressed air leak detection is the systematic identification, recording, repair, and verification of unintended air losses from a compressed-air system.

Common leak locations

Leaks may occur at:

  • Fittings
  • Hoses
  • Couplings
  • Valves
  • Regulators
  • Filters
  • Drains
  • Cylinders
  • Distribution joints
  • Unused branches

Practical example

An ultrasonic survey identifies leaks across a production area and creates repair work orders with estimated loss.

Why leaks matter

Leaks increase energy cost, reduce pressure, increase compressor loading, and reduce standby capacity.

Program controls

A leak program should tag findings, estimate severity, assign work, verify repair, and trend recurrence.

Common mistake

Performing surveys without creating and closing repair work produces a list rather than an improvement program.

Compressed Air Leak Detection FAQs

How are compressed-air leaks detected?

Ultrasound, listening, soap solution, flow analysis, and pressure testing.

Why repair leaks?

They increase energy cost, compressor loading, pressure loss, and capacity demand.

What makes a leak program effective?

Tag, estimate, prioritize, repair, verify, and trend each finding.
