  If your NVE Blower is creating unusual noises or vibrations, it could be due to several reasons. The rotors might be worn, in which case you should verify internal clearances and replace or rebuild the blower as necessary. Worn bearings could also be the cause, requiring a blower rebuild. Additionally, if the rotor timing is off, having the blower rebuilt is the suggested solution.
