Section 8.0 Maintenance
During normal operation and even after cleaning, a small dust layer remaining on the inside of the
bags assists in the collection.
Fine dust that cannot be blown out will become deposited/trapped in the filter fabric. Therefore,
the filter bag will lose its efficiency over time due to these deposits in the fabric and wear and
tear. In applications with a high fine dust concentrations, the filter bags should be cleaned
mechanically through “beating”, “shaking” or via optional shaker systems.
8.2 Service and Repair:
Only specially trained or certified personnel should perform service and repair.
Before any work can begin, the main switch must eliminate the power supply and it must be
ensured that no unintended restart can occur. An option would be to lock out and tag out the main
switch. Accumulated energy, such as in a compressed air system, must also be interrupted or
discharged before commencing the work.
For service and repair work done in the dust laden air, at a minimum the following safety
equipment must be used.
•
Respiratory Protective Device, possibly with fresh air supplies
•
Goggles or shield mask possibly in connection with fresh air supply in toxic dust Applications,
supplement with required special equipment. For fire/explosive dust, the following must
also be used:
•
Fire Retardant Suit
•
Fire Retardant Working Gloves
•
Safety Footwear
•
Safety Helmet
•
Sparkless tools wherever possible
Inspection of filters from the clean air side/in the clean air chamber should only be performed
when the collector system has completely stopped. The personal safety equipment referred to
above should be used.
If cleaning is performed using a vacuum cleaner, protection must be provided against static
electric charging.
Boring of holes in dust collector housing or adjoining pipe ducts should only be performed only
when the system is off, has completely stopped and has been cleaned, While doing so, make sure
no heat generated.
