SECTION 500-PREVENTIVE MAINTENANCE AND TROUBLESHOOTING
Your Gold Series Dust Collection system requires very little maintenance to achieve maximum life and
efficiency. The following items should be periodically serviced:
500.1 Filter Elements
Pressure drop across Gold Cone filter elements normally increases rather rapidly when the filter elements
are new and clean, but then climbs much more slowly throughout the rest of their service life. Typically,
when the Gold Cone elements cannot be cleaned below a differential of 6 inches water gauge or greater,
they have reached the end of their service life and require replacement. Other indications for
replacement are cartridges that have been in service over 2 years or cartridges that have been damaged
by moisture, high heat or other perilous conditions.
500.2 Hopper
At the start/end of each shift, check the hopper or discharge container at the bottom of the unit. Locate
the handle on the front of the slide gate (if equipped) and pull to ensure that the gate is open. Dispose of
any waste accumulation according to federal, state and local environmental regulations. Check the tracks
located on either side of the gate for dust accumulation. Remove any buildup to maintain free operation
of the gate. During operation, the gate should remain open allowing the collected material to flow freely
into the discharge container. Under no circumstances should the hopper be used to store collected
material. Empty and replace full collection containers frequently. Do not over fill containers, as this will
inhibit performance of the collector.
500.3 Fan Motor Lubrication
The most common cause of premature bearing failure is improper lubrication. The fan motor provided
with Gold Series dust collectors may vary. Farr often provides the fan with the collector, but many times
the fan is provided by other sources. If Farr provided the fan, it will be one of two types. One type has
sealed-for-life bearings and requires no maintenance. The other type motor provided with the fan has
grease fittings on the top and bottom of the motor. If safety permits, the initial lubrication may be done
while the motor is running until some purging occurs at the seals. Hours of operation, temperature and
environmental conditions will affect the lubrication frequency. Adjust frequency depending on the
condition of the purged grease.
Use extreme caution when working around rotating machinery. Remove all jewelry, loose clothing
or anything that could encounter rotating components. Failure to follow these precautions may
result in serious injury such as the loss of limbs or death!
Lubricate the grease fittings with a high quality NLGI No. 2 or No. 3 multi-purpose ball bearing grease
having rust inhibitors and anti-oxidant additives.
Lubricate bearings prior to an extended shutdown or storage period. Rotate the motor shaft monthly to
prevent corrosion.
Suggested greases are:
• Shell Alvania No. 2
• Mobil Mobilith 22
• Gulf Gulfcrown No. 2
• American-Rykon Premium 2
500.4 Solenoid and Diaphragm Valves
The solenoid and diaphragm valves may require periodic maintenance depending on the quality of the
compressed air supplied to the unit. Check each valve periodically to see that it is operating properly and
if required, refer to Appendix A & B for maintenance of the valves.
