Why does your industrial centrifugal fan vibrate continuously?

Do you think the fan vibration is due to worn bearings?
Not always.
In many cases…
the real problem lies in poor impeller dynamic balance.
When the impeller is not perfectly balanced…
it generates centrifugal force with every rotation.
This means:
❌ More vibration
❌ Bearing failure
❌ Higher energy consumption
❌ Shorter lifespan
At SIMO BLOWER, every impeller undergoes dynamic balancing testing to ISO 21940 G2.5 standards before leaving the factory.
Because a smoothly running fan is not only quieter—
it's also more efficient, more reliable, and has a longer lifespan.
