What to do if SystemAir Fan air output is not sufficient?
- M
  Mary BrockAug 5, 2025
  If the air output of your SystemAir Fan is not sufficient, consider these possible causes and solutions: * Ensure the fan impeller turns in the correct direction by verifying the electrical connection. * Check that the electrical connection matches the wiring diagrams. * Adjust the airflow shutters to ensure they are fully open. * Remove any blockage in the air inlet or duct system. * Confirm the product is suitable for the installation location. * For EC motors, check the ambient temperature and ensure sufficient space around the motor for cooling. If the air pressure is too low, make necessary changes to the duct system and installed components to increase it.

Why SystemAir K 160 EC Fan motor does not rotate?
- D
  Denise HallAug 9, 2025
  If the motor of your SystemAir Fan does not rotate, it could be due to several reasons: * A component in the power supply might be defective; check the power supply, replace any defective components, and reconnect it. * The electrical connection may be incorrect; ensure it agrees with the wiring diagrams. * The motor protection might be released due to overheating; let the motor cool, reset the motor protection, and identify the cause of overheating. * A phase loss might have occurred; if it's a 3-phase motor, ensure no phase is missing.

How to fix unusual noise when SystemAir K 160 EC Fan starts or operates?
- P
  piercelisaAug 14, 2025
  If there is unusual noise when your SystemAir Fan starts or operates, it might be due to strain in the duct system connections. To resolve this, loosen the connections, correctly align the parts of the duct system, and then tighten the connections.

What to do if SystemAir Fan does not operate smoothly?
- U
  uwalkerAug 18, 2025
  If your SystemAir Fan does not operate smoothly, consider the following: * Ensure the electrical connection is correct so that the fan impeller turns in the correct direction. * Clean the fan impeller carefully if there is dirt on it. * If the fan impeller has deformations because of too high temperatures: * Replace the fan impeller. * Make sure that the temperature of the transported air is not higher than the value on the name plate. * Ensure the product is correctly installed and check the duct system if there are unusually strong vibrations in the product or the duct system. * Increase or decrease the fan speed until the product operates smoothly if it is operated in a resonant frequency range.

Why is SystemAir K 160 EC electronic components or the motor overheated?
- T
  Taylor SalazarAug 22, 2025
  If the electronic components or the motor of your SystemAir Fan is overheated, it could be due to: * Motor overload or high ambient temperature. Let the motor cool, reset the motor protection, and find the cause of the overheating. * Insufficient cooling. Ensure adequate space around the motor for cooling. * The product is not applicable for the installation location.

What to do if SystemAir Fan speed does not get the nominal value?
- B
  Benjamin RojasAug 27, 2025
  If the fan speed of your SystemAir Fan does not reach the nominal value, consider these possible causes: * Defective motor winding: If possible, measure the resistance to check the motor winding. * Incorrect speed control setting: Set the speed control correctly. * Mechanical blockage: Remove any blockage preventing the fan impeller from turning freely. * Phase loss: If it is a 3-phase motor, ensure that no phase is missing.

What causes SystemAir Fan thermal contacts, PTC or resistors to be released?
- E
  Edwin WattsAug 30, 2025
  If thermal contacts, PTC, or resistors are released in your SystemAir Fan, it could be due to several reasons: * Ensure the fan impeller turns in the correct direction by verifying the electrical connection. * If the motor is a 3-phase motor, make sure that no phase is missing. * The motor may be overheated. Check the motor cooling impeller, and if possible, measure the resistance to check the motor winding. * The capacitor may not be connected correctly. Connect the capacitor correctly, referring to the included motor wiring diagram. Note: This is not applicable for EC motors or 3–phase AC motors.
