The invention relates to a full oil-free air compressor for a railway vehicle, which comprises an air inlet filter for filtering ambient air sucked into the compressor; a crankcase chamber capable of buffering air from the intake air filter; the front cooling structure is used for cooling air flowing through the crankcase cavity; the first-stage compression air cylinder is used for performing first-stage compression on the air from the front cooling structure; the intermediate cooling structure is used for cooling air from the first-stage compression air cylinder; the second-stage compression air cylinder is used for performing second-stage compression on the air from the intermediate cooling structure; and the rear cooling structure is used for cooling air from the second-stage compression air cylinder. A crankcase air inlet mode is adopted, ambient air flows in the crankcase and then enters the front cooling structure, the air suction temperature of the first-stage compression air cylinder is reduced, the e
