Care and Maintenance
A regular and systematic inspection of all fan parts is the key to good fan maintenance. The frequency of inspection should be
determined by the severity of the atmospheric conditions. Components requiring service are generally the moving parts of the fan
assembly. They include the following:
PROPELLER: The propeller in an axial flow fan must be kept reasonably clean if it is to perform properly. Fans handling fresh
air for ventilating purposes will seldom need cleaning. Fans exhausting process air should be cleaned as required.
SHUTTERS: Periodically check damper blades and remove dirt accumulation. Bronze damper bearings should be checked for
smooth operation.
SCREWS AND BOLTS: Check for tightness throughout the assembly.
