Greenbuild Chicago - Dyson Air Multiplier

Greenbuild Chicago – Dyson Air Multiplier

The Greenbuild show featured tons of cool, state of the art products, but many of them were geared to commercial or industrial use. I was more tuned into products for residential use. The Dyson Air Multiplier was one that I found fascinating. It’s probably the first time since the fan’s invention that there’s been any kind of significant change to the way the product looks or functions.

The Air Multiplier “fan” actually looks more like a Quidditch goal – basically a round hoop on a stem. Super sleek: no blades and no grill. It blows air but you can’t even see how it works.

Apparently, it draws air in through small holes on the stem. The air is then accelerated through an annular aperture. This creates a jet of air that passes over an airfoil-shaped ramp, channeling its direction. Surrounding air is drawn into the airflow, amplifying it 15 times. For some reason you feel the air more as you move AWAY from the fan. You can learn more about it here.

I don’t really get it but it is cool. Not cheap, though. One of these babies will run you $299 for the table model and $449 for the tall towers.
