Abstract (en)
[origin: WO9913272A1] The invention relates to a suction and filtering system (10) to obtain and process fresh air, comprising an air feed device (12) consisting of at least one air collector tank (13) and at least one respective air suction device (19) connected to said tank enabling air to flow throw. The air collector tank is surrounded by at least one filter layer (62) of solid particles. The filter layer is defined by a less permeable layer in the direction of the ground surface. At least one liquid collector tank (15) which is open in the direction of the air collector tank is arranged underneath said air collector tank (13).
