ID Fan Services
ID Fan Services
ID (Induced Draft) fans are critical in boilers and process plants to maintain stable draft and safe operation. Unbalance, dust buildup, erosion and alignment issues can create high vibration and repeated bearing failures. Our ID fan services include inspection, impeller repair/refurbishment support, onsite/in-shop dynamic balancing and vibration analysis so your fan runs smoothly and reliably.
Applications
- Boiler ID fans (bagasse/coal/biomass)
- Sugar factory and power plant draft systems
- Furnaces, kilns and process exhaust fans
- Dust collectors and ESP/bag filter fans
- Fans after overhaul, impeller change or repair
What we help with
- Condition checks for erosion, buildup, cracks and looseness
- Impeller repair/refurbishment guidance and replacement recommendations
- Onsite dynamic balancing with portable instruments (where feasible)
- Vibration analysis to identify misalignment, looseness, resonance or bearing issues
- Verification run, reporting and follow-up recommendations

Our Few Benefits
Reliable ID fans maintain stable draft, reduce vibration and protect bearings in critical boiler/process operation.
Typical improvements
- Reduced vibration, noise and heat
- Longer bearing, seal and coupling life
- Better airflow/pressure performance and efficiency
What is an ID fan (Induced Draft fan)?
An ID fan maintains negative pressure and draft in boilers and furnaces by extracting flue gas through the system. Stable ID fan operation is important for combustion efficiency and safe plant operation.
Can you do onsite dynamic balancing for ID fans?
Yes, where access and safety conditions allow. We use portable instruments to measure vibration and calculate correction weights on the installed fan. If onsite balancing is not feasible, we can recommend in-shop balancing/overhaul options.
What are common reasons for ID fan vibration?
Common reasons include dust buildup, erosion, damaged blades, loose foundation/fasteners, misalignment, bent shaft and worn bearings. We support balancing and vibration analysis to confirm the real root cause.
What details do you need before ID fan service?
Fan type, operating RPM, access/guarding details, where weights can be fitted, and your shutdown window. A short vibration history and photos of the fan/drive help us plan the job.
