Observation
The fan bearings showed impacts at 4.5x turning speed with harmonics, and the FFT displayed a haystack pattern (broadband noise), suggesting a lubrication issue.
Recommendation
The AssetWatch Condition Monitoring Engineer recommended greasing the bearing to see if vibration levels would decrease.
Resolution
The customer lubricated the bearings, which reduced and stabilized vibration levels. The trend will continue to be monitored.
