75 HEPA filter High Efficiency Particulate Arrestance. Hepa filter is 99,97% efficient until 0,3 micron impurities. Multipurpose washable filter It combines all the advantages of the cartridge filter but with the plus that it can vacuum both dry and wet at the same time. It can be washed with tap water. Filter shaker It clears filter from dust without touching it or opening the vacuum cleaner; the vacuum efficiency is kept at max. Foam system: the machine is equipped with connection for compressed air and pressure gauge for foam cleaning. Using the lance with the hose a thick foam can be produced that will stay on the dirty components, giving more effectiveness to the detergent. Number of motors: It explains how many motors there are in the vacuum cleaner. Ignition is independent in order to increase progressively the performances. The working system (whenever it is more than one) is in parallel, so the air suction increases and the depressure is steady whenever the motors are progressively switched on. Anti electrostatic current device Dust rubbing at high speed against vacuum cleaner walls creates a magnetic field that neutralizes on the user with small and annoying discharges also through plastic material. This certified system removes this phenomenon on the machine, granting best comfort and safety for the user. Paper collector filter Allows filtering and collection (with a valve) of rough dirt without dirty the tank whenever it is time to replace it. It is useful for dry waste, also in combination of other thinner filters. Cloth filter The cloth consistency and its shape allow a simple cleaning phase and the reusage of the filter. It can be used only for vacuuming dry waste; if combined with nylon filter it is possible to work for a longer period of time. Cartridge filter The continuous folders arranged in circle allow a higher filtering surface in a smaller area. More cleaning autonomy with a thin filtering action. It can be used only for vacuuming dry waste and it is re-usable. Dry vacuum cleaners/wet & dry vacuum cleaners and Carpet cleaner - Spray extraction units
