Main point
The dirty and clean air sections must be reviewed as an assembly of interfaces, not just as two named chambers. The filter connection, tubesheet and relevant partition details belong in the same integrity review.

Information to record
Use the equipment drawing to identify potential bypass interfaces and the inspection access provided. Record the exact location of observed dust patterns or defects. Distinguish a suspected path from a confirmed finding and keep photographs linked to component or drawing references.

Review and acceptance
Agree the assessment and repair method with the responsible service or engineering team. Define how the restored interface will be checked and how outlet performance will be confirmed afterward. Keep the cause review separate from the decision to replace filter elements.

FAQ: Does replacing bags rule out every bypass path?
No. Review the complete separation boundary and the evidence for the actual defect.
FAQ: Is clean-side dust alone enough to locate the opening?
It supports investigation, but the exact path requires confirmation through the agreed inspection.
