6. Maintenance, working information
Various fluxes, flux components as well as different dust particles in the extracted air
can significantly reduce the filter's working life.
The sub-micron particles in the air increase when soldering or welding on varnished
insulated wire. The standardised F5 filter mat should be exchanged for a class F7 fine
dust filter for these or similar applications.
A compact filter with a greater quantity of active carbon (without particulate air filter
stage) should be used when extracting adhesive vapour.
Filter changes
