A powerless ion air gun is provided to secure use convenience by excluding a high-pressure power cable by generating electricity with the compressed air. A powerless ion air gun for removing static electricity by jetting the compressed air is composed of: a power generating unit installed at a compressed air passage; a control unit disposed at the compressed air passage to boost the voltage of electricity generated from the power generating unit and provided with a boosting coil cooled by the compressed air flowing to the inside; and an ejection unit(400) for ionizing the compressed air by using high-pressure current transmitted from the control unit. The power generating unit comprises an impeller(240) and a generator(230). The ejection unit has a compressed air ejection port formed at an insulated nozzle body. A discharge needle is disposed in the ejection port.
