What is the purpose of the dust blower cleaning the impeller? When the fan is running at low speed?

Before the fan impeller leaves the factory, it must be corrected for dynamic balance. When the dust on the impeller accumulates too much, when cleaning, the fan is usually stopped. From the inspection hole or the inlet, the surface of the impeller is brushed with a soft brush and then reset. Re-balance the site to ensure smooth operation;

However, if the fan can't stop, it is necessary to reduce the fan speed, clean it during operation, and can't flush the impeller with water at high speed. It is necessary to know that the impeller in high speed is equivalent to the speed of more than one hundred kilometers per hour, and the water impacts the blade. Will cause structural damage.
