The machine is an air purifier designed for suction of wet mists containing dust produced during machining operations such as cutting, grinding and polishing objects in marble, stone, granite and composite materiale with cement-based binders or resins. It consists of a cylindrical body with polluted air input from below, forcing the air to rise upwards through a Iayer of polypropylene (PP) filling bodies, which are washed by atomised water jets. In its excursion towards the outlet, the air passes through a particular separator, shedding transported microdroplets. A tank is mounted underneath housing a submersible pump that feeds the washing ramp with open cone spray nozzles. Models with a filtration capacity for Ioads from 5000 3 to 30000 m3.
