The filters, to be applied in the suction plenums, prevent particles contained in the stale air, especially from kitchens, from depositing in the suction channels. Their replacement, two or three times a year, reduces the frequency of cleaning the suction channels to 5 years. Replacing the filters is extremely simple and fast: extract the nozzle, fixed with springs, replace the filter, and reposition the nozzle. The G4 class filter blocks almost all particles larger than 5 microns (average efficiency > 90% with synthetic dust) and a large portion of those between 0.3 and 3 microns. The conical filter is available for plenums of two diameters: DN 100 and DN 125.
