The invention relates to a dynamic self-cleaning filtering system which uses cartridge filters (8) into which pressure sensors are inserted such that a pre-established pressure drop value defines the actuation of the self-cleaning system. Said system consists of a store (11) of compressed air, which is supplied by the train's own pneumatic system which, by means of the corresponding electrovalves and diffusion nozzles, injects high-pressure air into the filter (8), decreasing the amount of dust and sand on the outward-facing outer surface thereof. |
