ChecklistApproved
Compressed-air leak checklist
Leaks can waste up to 30% of compressor output. Run this checklist during a non-production shift.
16 Sept 20263 minValid until 3 Oct 2027
Before you start
Stop production but keep the compressor running.
Pressure-decay test
Time how long the receiver takes to drop from working pressure to half. A fast drop means significant leakage.
Usual suspects
- Quick couplings and hoses
- Condensate drains
- Filter-regulators
- Worn pneumatic tools
Suggested actions
- Run a pressure-decay test while the line is stopped
- Tag and list every leak found
- Lower compressor set pressure to the real minimum required
Possible causes
- Leaks at fittings, hoses and drains
Required documents
- Compressor specification and running hours
Warnings
- Never touch a high-pressure air leak with your hand
