16.1 Remplacement of cartridges
The filtering cartridges life expectancy is only limited to it’s resistance to the dust to be filtered
which in most cases does not require periodic changes.
However, if a cartridge should tear or be punctured, replacement of such should be performed as
soon as possible.
16.2 Remplacement of cartridges
Prior to changing the cartridges, shut down the blower(s), screw conveyor(s), rotary valve(s),
control panel(s) and any other adjacent equipment. Lock all related breakers in the electrical
panels. Shut down and bleed the compressed air line feeding the collector.
Maintenance staff must wear protective goggles and an adequate respiratory apparatus. Purge the
system of all gazes and vapours other than air. Ensure the air flow is shut off and that the interior
temperature is at a safe level.
Follow these steps to remove the cartridges.

The use of safety equipment and adequate protection is
needed for the changing of cartridges. The dirty cartridges
may be heavier than expected. Use caution when removing
the cartridges to avoid injury. Do not drop the cartridges.
