An apparatus for suction and filtration of volumes of air containing particles in suspension, constituted by an external casing (10) obtained by joining two separable parts (11,12) and comprising within it: a first filter element (40), made up of three progressive-filtration diaphragms; an impeller (20) for suction and execution of a second filtration, of a contrifugal type; and a second element (50) which is able to guarantee a third filtering stage. The apparatus moreover comprises systems for discharging the pollutant matter collected by the action of the filters, as well as mechanisms for its lifting and positioning. The present invention reveals its main advantages in the compactness of the system and in the ease of execution of the operations of maintenance, as the same time guaranteeing a high efficiency. |
