| Symptom | Technical Root Cause | Required Action |
|---|---|---|
| Slow Depressurization | Muffler Dust Loading / Clogging | Clean Housing / Replace Filter |
| Abnormal Noise (High Pitch) | Relief Valve Partial Seat Failure | Function Test / Replace Seal |
| Delayed Vessel Release | Exhaust Path Restriction | Purge Decompression Lines |
| Vessel Over-Pressure | Relief Valve Blockage/Seizure | MANDATORY VALVE REPLACEMENT |
Exhaust Logic
Rapid decompression is a technical safety mandate. If the exhaust muffler is dust-loaded, the blast pot cannot release pressure instantly when the deadman handle is released. This delay creates a "run-on" hazard where the operator continues to blast without control. Moisture separators are critical here; damp air causes exhaust dust to turn into a technical "concrete" inside the muffler housing.
Inspection Intervals
- Daily: Visual check of muffler exhaust port
- Weekly: Disassemble & clean silencer housing
- Monthly: Relief valve lift-pressure test
