Condition Monitoring of Supply Fan Unit in Pharmaceutical Facility

This technical report outlines the condition monitoring of a supply fan unit critical to operations in a pharmaceutical manufacturing facility. The fan is essential for maintaining airflow and environmental conditions necessary for compliance and safe operation. The report details how early detection of abnormal noise and vibration levels in the fan bearings led to the identification of potential failures. Following a structured condition monitoring program implemented by AVT Reliability since 2021, engineers were able to analyze vibration data, confirming bearing wear consistent with outer race deterioration. The findings prompted a planned maintenance intervention during a scheduled shutdown, allowing for the replacement of the bearings without disrupting production. Post-repair data indicated a successful resolution of the fault, with vibration levels returning to acceptable limits as per ISO 10816 guidelines. The report emphasizes the importance of condition-based maintenance in preventing unplanned downtime and ensuring reliable plant operations.
