  • Device for transport of air and/or cleaning of air using a so called ion wind
    Patent number: 5982102
    Abstract: A device for transporting air with the aid of so-called electrical ion-wind, said device including at least one corona electrode (10), e.g. thread shaped, that extends transverse to the air flow path, and at least one target electrode (16) and one duct electrode (12) provided downstream of the corona electrode, said target electrode (16) and said duct electrode (12) being connected to respective terminals of a d.c. voltage source (11) having such a voltage that a corona discharge generating air ions occurs at the corona electrode. The duct electrode (12) is designed of both a current carrying frame and an electrically insulating casing therearound and hence the around the corona electrode (10) generated ions will not be able to reach the current carrying frame of the duct electrode (12).
