Dyson Bladeless Fan

Dyson Air Multiplier, the fan to keep you cool during a scorcher.

A 115 degree heat index has planted itself in the Twin Cities and there’s no relief in sight. People are searching for ways to stay cool, proven by the increase in traffic here at Mall of America. Whether or not you have air conditioning, everyone needs a great fan and we happen to have just the one for you – Dyson’s Air Multiplier fan. This Dyson bladeless fan draws air in through a mixed flow impeller – a combination of technologies used in turbochargers and jet engines. And with no blades, it’s safer and easier to clean. How cool (no pun intended) is that?

The Air Multiplier uses friction in the air to push out its cool breeze. Around the rim of the circular fan is a little opening from which jets a very thin (1mm or so) stream of air at 55 mph. That thin stream of air pulls more air into the stream thanks to the aforementioned friction – Physicists call this process entrainment.

At the same time, the air that gets pushed away from the ring towards your beautiful face creates an area of low pressure – not quite a vacuum, but the same effect – in the ring. That low pressure pulls in more air from behind the machine (filling the gap) which is then in turn drawn into the air stream. That’s called inducement.

Safe

  • A Dyson Air Multiplier™ fan has no fast-spinning blades. It’s safe.

Easy to clean

  • No blades means there are no fiddly safety grilles to take apart. To clean a Dyson fan, simply wipe with a cloth.

Dimmer switch power control

  • Conventional fans have limited power settings. A Dyson bladeless fan allows you to precisely adjust airflow power.

Touch-tilt

  • Dyson table fans pivot on their own center of gravity. They aren’t top-heavy like some other fans, and stay put without clamping.
