A centrifugal fan preventive maintenance schedule lists the checks and jobs done on the equipment at fixed intervals, how long each takes, and in what order of frequency, so problems are found before the centrifugal fan fails. This page gives the schedule used in the PlantOps360 task library for centrifugal fan (process, id / fd fan), which follows common industry practice for general-purpose equipment. It is also searched for as ID fan, FD fan, induced draft fan, forced draft fan.
The maker’s manual and your site safety procedures always come first where they differ. Intervals set by law differ by state.
Centrifugal fan preventive maintenance schedule and checklist
| How often | Task | Estimated time |
|---|---|---|
| Daily | Check bearing temperature and for abnormal vibration or noise | 3 min |
| Weekly | Check damper or inlet vane operation and linkage | 10 min |
| Monthly | Grease bearings as per OEM; check belt tension or coupling | 20 min |
| Monthly | Measure vibration at bearings and record trend | 20 min |
| Quarterly | Inspect impeller for deposits, erosion or imbalance; clean as required | 60 min |
| Half-yearly | Check foundation bolts, flexible joints and casing for cracks or leaks | 60 min |
| Annual | Inspect impeller, shaft and bearings; check balance and alignment | 240 min |
Centrifugal fan maintenance frequency and yearly workload
At the estimated times, one centrifugal fan needs about 45 hours of preventive maintenance a year. The biggest single job is “Inspect impeller, shaft and bearings; check balance and alignment” at 240 minutes, done annual. Multiply by the number of units you have to see the workload for your plant.
| Frequency | Tasks | Time per round | Hours per year |
|---|---|---|---|
| Daily | 1 | 3 min | 18.3 h |
| Weekly | 1 | 10 min | 8.7 h |
| Monthly | 2 | 40 min | 8.0 h |
| Quarterly | 1 | 60 min | 4.0 h |
| Half-yearly | 1 | 60 min | 2.0 h |
| Annual | 1 | 240 min | 4.0 h |
What goes wrong on a centrifugal fan without preventive maintenance
- Impeller imbalance from dust build-up
- Bearing failure
- Belt wear or slip
- Damper and inlet vane faults
What to watch between services
- Vibration
- Motor current
- Bearing temperature
Safety and statutory notes for centrifugal fan maintenance
Fans can restart on their own through draught. Lock out and secure the impeller before work.
