I could be wrong, but I think that the Dyson "bladeless" fan has, in its base, a regular ol' fan, with blades. As I understand it, that fan blows air out of holes in the trailing edge of the circular airfoil. Aerodynamic effects cause a larger volume of air to be dragged through the airfoil than the fan itself is pushing through the little holes.
If that's so, it ought to be no worse a generator of RFI than any other fan. 73, Wayne Conrad KF7QGA On 06/19/12 12:24, Ron D'Eau Claire wrote: > Has anyone every operated one of those in close proximity to an HF rig? > > We built such fans in College waaaaay back in the 1950's and they were a bad > of an RFI generator as any Tesla coil or Van De Graaf generator in the lab! > > After all, they work by electrostatic discharge. > > Ron AC7AC > > -----Original Message----- > > Solution - the Dyson blade less fan.
