The “F” range filters for extraction and deodorization of soldering fumes, has been designed and realised allowing a modularity in the filtering devices which greatly extends their field of use. Designed for the electronics industry for the extraction of fumes from work positions, up to 12, (F 1200), wave soldering devices, soldering pots, they are also used in the chemical-pharmaceutical sectors, gold industry, vocational schools. Filtering takes place through three different work stages and increasing efficiency, monitored visually by the differential pressure switch or through a re-usable filtering cartridge; in this version the differential pressure switch is supplied as an optional. In the version with activated carbons, the latter cannot be regenerated and must be changed regularly.
