Dust Collector Filter Bag Failure Troubleshooting Guide
Unexpected bag failure should be investigated from the failure location, operating data and collector condition before a replacement material is chosen.
Common Failure Patterns
- Abrasion at the cage, tube sheet or inlet side
- Chemical attack, hydrolysis or oxidation
- Thermal shrinkage, hardening or heat damage
- Seam, snap-band or bottom failure
- Blinding from moisture, oil or sticky dust
- Damage from cleaning pressure or misalignment
Evidence to Collect
Record the damaged location, bag age, pressure-drop trend, normal and peak temperature, gas chemistry, dust properties, cleaning settings and cage condition. Retain a failed sample and drawing where possible.
