6.0 Indications – Disturbance origins
- If the thermal protection trips this could be the result of dirt build-up, a hard running impeller and/or bearings.
Too high winding temperature through insufficient motor cooling, or too high air flow temperature could be the
cause of disturbance.
- Abnormal noises can mean worn out bearings.
- Vibrations can originate from an unbalanced or dirty impeller or due to the installation.
- Extreme performance reduction can occur if the fan must work against too high resistance of the ventilation system
or if there is a lack of sufficient supply air (causing also higher sound level).
