SECTION 3: COOLER ASSEMBLY
3.2
The Pneumatic Motor And Cooling Fan Blade
The pneumatic motor and cooling fan blade provided is relatively maintenance free
and there are only a few points that should be followed to assure satisfactory
performance. Review the bullet points during installation and operation.
Note:
The fan blade assembly should be inspected at time of installation and after
every 4 weeks of operation to ensure integrity of the fan blades. DO NOT
attempt to repair a damaged fan blade. A damaged fan assembly should only
be replaced with factory original part. The air supply line to the cooler motor-
fan assembly should be disconnected if fan service is to be performed. A
damaged pneumatic motor can affect the integrity of the fan blades. If the
cooler pneumatic motor fails the fan blade assembly should be inspected for
stress cracks by a qualified person, or have the fan blade assembly replaced.
The cooling fan may need replacement every 1-2 years depending on severe
duty found at site.
Caution!
The exhaust stream from the pneumatic motor may contain solid particles or
oil aerosol. Wear eye and skin protection at all times while in the proximity of
this equipment.
Ensure the oil mist delivery to the motor is properly adjusted. A data table of
adjustments has been provided at the end of this section.
Ensure pneumatic motor outlet muffler is clean and unobstructed of dirt particles
that will prevent normal operation of the motor.
Ensure the delivery pressure to the motor is set per the data table provided at the
end of this section.
For long term storage (several weeks) the motor should be properly lubricated at
time of start up to ensure trouble free and long term performance.
Important!
The pneumatic cooler motor provided requires oil lubrication. The type of oil
recommended is a non-detergent SAE#10 air tool oil. Flushing of the motor may be
required to remove excessive dirt, foreign particles moisture or oil. Use only air tool
flushing solvent. Do not use kerosene or any other type of combustible solvents to
flush motor.
