FANS MAINTENANCE

Following are some of the recommended performance monitoring and maintenance tasks. The frequency of
these tasks should be as indicated or based on operating experience -

  • Vibration Analysis - semi annual
  • Greasing of fan bearings (not for sealed or double shielded bearings) - semi annual
  • Greasing of fan motor bearings (not for sealed or double shielded bearings) - semi annual
  • Drive belt inspection or replacement - annual
  • Vane axial fan blades and hub inspection - annual

If the fan and/or motor bearings are sealed or double shielded, they should be replaced periodically
depending on the vendor specified life.
