%X This research article describes experiments using several Asymmetrical Capacitors prototypes (AsC) with the objective to reproduce this unusual physical phenomenon, as well as to show its exceptional characteristics. Some results are published for the first time. The operating voltage was increased up to 31kV using a DC generator. The AsC levitated in every experiment, simultaneously generating a gas current from the lowest superficial area electrode. Although this phenomenon has been known for over one century, its scientific basis remains unknown and there isn't a model that properly explains its behavior under different conditions. It was proved that it works as a conventional electrostatic separator because it eliminated solid particles from a gas sample either confined in a container or flowing, with the advantage of low energy requirements. In the same way, at operating conditions, it produces ozone in a controlled way, as in the corona effect. El presente art赤culo de investigaci車n describe experimentos realizados utilizando prototipos de condensadores asim谷tricos (CAs), con el fin de reproducir este inusual fen車meno f赤sico y mostrar algunas de sus excepcionales caracter赤sticas. Algunos resultados aparecen por primera vez en la literatura. Se utiliz車 un generador de 31kV CC y se observ車 que en todos los casos el CAs levit車, gener芍ndose simult芍neamente una corriente de gases en el electrodo de menor 芍rea superficial. Aunque este fen車meno se conoce hace m芍s de un siglo, su fundamento cient赤fico es a迆n desconocido y no hay un modelo que explique satisfactoriamente su comportamiento a diferentes condiciones experimentales. Se comprob車 que opera en forma equivalente a un separador electrost芍tico convencional eliminando part赤culas s車lidas de un gas encerrado en un recipiente o en flujo, con la ventaja de un bajo consumo de energ赤a el谷ctrica. Igualmente, a las condiciones de operaci車n, produce ozono de forma controlada, similar al efecto corona.
