Any wear or structural damage on other airstream components?

As mentioned previously in this manual, excessive vibration can cause premature motor failure that could lead to catastrophic failure of the blower. After performing any routine maintenance, the vibration readings should be taken.

New readings should be taken (maximum every 12 months) and compared to the readings you recorded in Table 3 during the initial startup. If any major differences are present, the cause should be determined and corrected before the blower is put back into operation.

The most common causes of vibration problems are:

• Misaligned sheaves and/or belts

• Poor blower inlet and/or discharge conditions
