Why is the air output of my SystemAir DVS Fan too low?
If the air output of your SystemAir Fan is too low, several factors could be the cause. First, ensure the rotor's rotation direction is correct by changing it if necessary. High pressure losses in lines can also reduce output, so consider different line guidance. Check that throttle organs are fully open. Finally, remove any obstacles blocking the intake or pressure paths.
How to fix a SystemAir DVS Fan that does not run smoothly?
If your SystemAir Fan is not running smoothly, several issues could be responsible. The rotor may be imbalanced, requiring re-balancing by a specialist. Adhesions on the rotor can also cause this; carefully clean the rotor and rebalance if needed. Material decomposition due to aggressive materials being conveyed may also be a factor; in this case, contact the manufacturer. Ensure the rotor's rotation direction is correct, and if the rotor is deformed due to excessive temperature, contact the manufacturer, install a new rotor, and check the bearings.
What to do if thermo-contacts/posistors have reacted in my SystemAir DVS?
If the thermo-contacts or posistors in your SystemAir Fan have reacted, there are a few potential causes. Ensure the capacitor is correctly connected. Also, check that the rotor is rotating in the correct direction and change it if necessary. If the motor is blocked, contact the manufacturer.
Why doesn't my SystemAir DVS Fan reach nominal speed?
If your SystemAir Fan does not reach nominal speed, the electrical switching devices may be set incorrectly; check and reset their settings if needed. If the motor coil is defective or the drive motor has been designed wrongly, contact the manufacturer.
What causes grinding sounds in my SystemAir Fan during operation?
If you hear grinding sounds during operation or when starting your SystemAir Fan, the intake line might be installed twisted. Loosen the intake line and realign it to resolve this issue.
