What to do if there is soiling on the impeller of my SystemAir AXC Fan?
If there is soiling on the impeller of your SystemAir Fan, clean it carefully and then rebalance it.
How to fix impeller imbalance in SystemAir AXC Fan?
If your SystemAir Fan has an impeller imbalance, rebalancing by a specialist company is recommended. Otherwise, contact Systemair.
What to do if my SystemAir AXC does not run smoothly?
If the SystemAir Fan isn't running smoothly, several factors could be at play. The impeller might be rotating in the wrong direction; in this case, change the direction of rotation, swapping two phases if it's a 3-phase motor. There could be deformation of the impeller due to excessive temperature; ensure the temperature doesn't exceed the certified value or install a new impeller. The wiring configuration might be incorrect; check and correct it, ensuring it's not Y instead of Delta. Blocked intake or pressure paths can also cause this; remove any blockages. If the motor overheated, check the cooling impeller (if used) and measure the motor winding (if possible), or contact Systemair. A missing phase could be the issue; check if all 3 phases are present. If the motor is blocked, contact S...
Why SystemAir AXC does not reach nominal speed?
If your SystemAir Fan isn't reaching its nominal speed, several issues could be the cause. The control units (if used) such as frequency converter or transformer might be set incorrectly; correct their settings. Check for a mechanical blockage and remove it. The supply voltage might be incorrect; check and re-establish the voltage supply. A faulty connection could also be the problem; after disconnecting from the power supply, correct the connection following the circuit diagram. If the temperature monitor has responded, allow the motor to cool down and resolve the cause of the fault. Ensure sufficient cooling and check if the ambient temperature is too high, verifying that the correct fan is used for your application. For a defective motor winding or improperly aligned drive motor, contac...
