Donaldson Company, Inc.
Donaldson Torit TBI fans are manufactured to high
standards with quality materials and components. Proper
maintenance will ensure a long and trouble-free service
life.
Regular fan maintenance should
include the following:
Check the fan wheel for any wear or corrosion,
as either can cause catastrophic failures.
Check also for the build-up of material which
could cause unbalance resulting in vibration,
bearing wear and serious safety hazards. Clean
or replace the wheel as required.
Lubricate the bearings, but do not over
lubricate.
Periodically inspect the shaft for dirt buildup,
corrosion and signs of excess stress or fatigue.
During any routine maintenance, all setscrews
and bolts should be checked for tightness. See
Torque Value Table.
The key to good fan maintenance is regular and
systematic inspection of all fan parts. Inspection
frequency is determined by the severity of the application
and local conditions. Strict adherence to an inspection
schedule is essential.
When installing a new wheel or cone, the
proper wheel-to-drive side plate must be
maintained as shown in Side Plate Clearance
Table. Inlet cone clearance should be uniform
around the circumference.
