Why is my Robuschi RBS making unusual noises and/or vibrations?
- L
  Lauren LambAug 5, 2025
  If your Robuschi Blower is experiencing unusual noises or vibrations, it could be due to several reasons. One possibility is that the rotors are making contact. Immediately stop the blower and check the internal clearances of the rotors and the gear. Another cause might be scale deposits in the compression chamber. In this case, you should clean the compression chamber and the rotors, balancing the rotors if necessary. Also, the issue might be the intake of foreign particles. Remove the foreign particles, clean the compression chamber, and check the clearances.

  Todd GutierrezAug 10, 2025
  If your Robuschi Blower motor doesn't start but makes a humming noise, there could be a few reasons. It might be that at least two of the electric connections have been cut off, or that one electric connection has been cut off. In both cases, check the fuses, terminal boards, and connection cables, and replace them if necessary. Another possibility is an incorrect electric connection, so you should check the electric system. Finally, the motor itself could be faulty, so check the electric motor.

  If your Robuschi Blower experiences automatic cut off just after start up, there could be several reasons. One possibility is that at least two of the electric connections have been cut off, or that one electric connection has been cut off. In both cases, you should check the fuses, terminal boards, and connection cables, replacing them if necessary. It could also be due to an incorrect electric connection, so check the electric system.

Finally, the issue might be the intake of foreign particles, so remove the foreign particles, clean the compression chamber, and check the clearances.

Why does my Robuschi Blower have high absorbed power?
- P
  Patricia EvansAug 23, 2025
  High absorbed power in your Robuschi Blower can be caused by scale deposits in the compression chamber. Clean the compression chamber and the rotors, and balance the rotors if necessary. Another cause might be the intake of foreign particles. Remove the foreign particles, clean the compression chamber and check the clearances.

  If you notice oil and/or liquid leakage in your Robuschi Blower, it could be due to worn gaskets. If this is the case, replace the gaskets. Another cause could be a worn drive shaft seal, which would require replacing the seal. Also, check if the oil level plugs are broken and replace the oil levels if needed.
