Suction is generated by two powerful By-Pass motors installed under a soundproof metal casing. The professional suction features are incredibly high-performance and far outweigh the vacuum cleaners in its category on the market. In this vacuum, there is a cartridge filter fitted under the filter chamber certified by BIA (Berufsgenossenschaftliches Institut für Arbeitssicherheit) in M Class with a 1µ filtration efficiency. Furthermore, thanks to the 40,000 cm2 of filtering surface, large amounts of dust can be vacuumed without clogging the filter, thereby ensuring operator safety. The industrial vacuum of Depureco's single-phase range is equipped with a JetClean® filter cleaning system that cleans the filter using the pressure differential between the inside and the outside of the vacuum. The filter can be cleaned without turning the suction motors off and without disconnecting the suction pipe. This vacuum cleaner is equipped with a Longopac® system that is used to bag the material directly without any contact between the operator and the vacuumed product.
