Centrifugal fan monitoring

Centrifugal fan and blower diagnostics: ultrasonic bearing checks, imbalance detection and resonance issues for reliable ventilation and ID/FD fans.

Centrifugal fan monitoring

Centrifugal fans in industry

ID/FD fans, process blowers and mine ventilation fans are production-critical. A single walk-down with ultrasound can screen dozens of fans without shutdown.

Common failure modes

Imbalance — from dust buildup, erosion or poor balance after repair.
Bearing wear — often accelerated by imbalance and over-greasing.
Resonance — when running speed hits a structural natural frequency.
Poor lubrication — over-greasing is 2–3× more common than starvation on fans.

SDT diagnostics

SDT340 measures RMS, peak and crest factor, records waveforms and trends against baseline. SDT270 supports large fan populations. LUBExpert cuts grease consumption 25–40% on multi-point fans.

Artesis EMCM

Aerodynamic changes — fouling, imbalance, duct blockage — appear immediately in motor load. Continuous current analytics flags drift before bearing damage spreads.

Field results

Sites with SDT + Artesis on fans report ~70% fewer emergency bearing changes, ~30% less grease use, 5–8% lower fan power from balance correction, and no catastrophic failures on major ID/FD fans.
