CleanSwitch
Executive summary
Exhaust fan on the MEGTEC CleanSwitch CS-600 (Job 10024557, shipped 02/2014) is exhibiting elevated vibration per technician observation during the walkdown — a leading indicator of bearing wear, impeller imbalance, or loose mounting that will progress to failure if left alone. The remainder of the unit — housing panels, stack, access platform, burner skid, ductwork, and damper bank — is structurally sound with no external defects. Priority next step is to collect vibration spectra on the fan motor and bearings and trend before the next production cycle.
Prioritized actions
- 1 WARNINGTake vibration readings on exhaust fan motor and bearing housings; capture spectra for trending.
- 2 WARNINGInspect fan impeller for fouling/imbalance and verify mounting bolt torque and coupling alignment.
- 3 WARNINGPlan exhaust fan bearing replacement and rebalance during next available production window.
- 4 INFORecord CleanSwitch Model CS-600, Job No. 10024557, ship date 02/2014 in CMMS asset record.
- 5 INFOTouch up paint wear on fan motor housing to prevent corrosion initiation.
Findings
Findings
1234Overall exterior of the CleanSwitch RTO is structurally intact — stepped exhaust stack, side housing panels, caged ladder, and elevated access platform all in serviceable condition with no corrosion, panel deformation, or duct leakage visible. Burner skid piping and gas train at ground level show no obvious leaks or mechanical damage.
No action required beyond routine PM documentation; retain this image as the baseline exterior reference.
1234Exhaust fan motor, scroll housing, ductwork, and tee damper actuator linkages are all externally intact, but the technician reported pronounced vibration at the fan during operation. That symptom — not visible in the photo — is consistent with bearing degradation, impeller imbalance from process fouling, or loosened mounting hardware, and represents the highest-risk condition observed during this walkdown. Minor paint wear on the motor housing is cosmetic only.
Collect vibration spectra on the fan motor and both bearing housings, then inspect impeller, mounting bolts, and coupling. Schedule corrective work before the condition progresses to a forced outage.
1234Nameplate is legible and undamaged, confirming the unit as a MEGTEC Systems CleanSwitch Model CS-600, Job No. 10024557, ship date 02/2014. This establishes the asset at roughly 12 years in service, which is relevant context for the developing fan vibration finding.
