According to the invention we are going to construct a system for cleaning of the filtering cartridges, or other filtering elements, present inside of an aspiration system for aspiration of airflow charged with dispersed particles, in order to avoid or retard the replacement or the cleaning of the cartridges due to their saturation. The system is characterized by being the number of the filtration elements, cartridges or other, more or equal to 2. One part of the filtration elements, generally one, is being cleaned by means of an airflow counter-current while the others continue to participate on filtering the airflow aspirated in its normal direction. This system is different compared to others, representative of the actual state of art, essentially due to the special system that avoids the cartridge being cleaned to be convolved in the airflow in aspiration.
