FILTRATION OF FUMES AND DUST
Important
Mechanical or electrostatic filtration systems are effective for the filtration of solid but not gaseous
particles (exterior discharge).
If recycling is effective (not recommended), make sure the workplace where the machine or machines
are placed is properly ventilated, so as to not reach the OELV (occupational exposure limit values) of
gaseous pollutants relating to the specific pollution generated by the method (welding, cutting).
Field of use
Filtration of solid particles and dry dust, non-flammable gas, with no risk of explosion.
— Zinc, paper, flour, plant leaves, graphite, alumina and other such dust is to be excluded, because
electrostatic discharge or welding splatter would present a risk for those using the filter.
— The air flow through the filter medium must not be at a temperature above 80 °C.
— This machine is not designed for extracting chemicals.
— The choice of machine is made to suit the pollutants to treat. Extraction at source of the pollutant is
only effective if the machine is operating at its nominal power (air flow at the nozzle).
Take particular care to :
— Not obstruct the air outlet of the machine
— Not introduce external elements into the filter (paper, cloths, cigarette butts etc.)
— Replace the filter medium with new original LINCOLN ELECTRIC medium, which alone can guarantee the
filtration characteristics.
— Replace the hoses if they are pierced.
— Regularly clean the metal pre-filter on those machines that have one.
