Kemper Dusty Evo Notice D'utilisation page 71

NOTE
If necessary, it is also useful to change the dust collection container
during this procedure.
7.2.3 Main filter change
The life of the filter inserts depends on the type and amount of deposited
particles.
As the dust accumulation in the filter increases, its flow resistance
increases and the extraction capacity of the product decreases.
Even in the case of products with an automatic filter cleaning system (if
present), deposits can reduce the flow resistance.
A filter change is required.
WARNING
Health hazards caused by welding fume particles
Inhalation of welding fume particles, especially welding fume particles
from welding processes on alloyed steels, can damage your health as
they are 'respirable'. Skin contact with welding fume particles can cause
skin irritation in sensitive individuals.
To avoid contact with and inhalation of these dust particles, wear
disposable overalls, protective goggles, gloves and a suitable Class FFP2
respiratory protection filter mask in accordance with EN 149.
NOTE
During the work described in the following section, pay particular
attention to the seal on the main filter. Only an undamaged seal allows
the product to achieve a high filter efficiency. Main filters with a damaged
seal must therefore be replaced every time.
NOTE
Please also refer to the "Installation" and "Use" chapters for the following
stages.
• Only original replacement filters, because they guarantee the
necessary filter efficiency and are matched to the product and its
performance characteristics.
