Dyson Air Multiplier fans grow up to Tower and Pedestal dimensions

James Dyson seems to have made the manipulation of air his life's mission, and his most recent product, the "bladeless" desktop fan, has apparently enjoyed enough success to merit an expanded range. You'll soon be able to splash a cool $450 on either of the elongated Tower (above left) or Pedestal Air Multipliers. They function along the same principles as the original: air is stirred up (by blades!) in the base and then thrust through the circumference of the device to deliver cool, calming, and buffet-free chills to your overworked self. Mind you, Dyson's keen to point out that only 7 percent of the air comes from its impeller-driven base -- most of the flow comes from "the inducement and entrainment of surrounding air." Boy, the company sure is getting its money's worth out of that thesaurus purchase. If you want to read more of this highfalutin stuff, go past the break for the full press release.

Dyson Fans Evolve From the Desk to the Floor

James Dyson unveils two new Air Multiplier™ machines

NEW YORK, June 21 /PRNewswire/ -- As the majority of the U.S. heads into the summer months, Dyson has the answer for sweltering temperatures with the latest Dyson Air Multiplier™ fans: the AM02 Tower and the AM03 Pedestal. Engineered for larger spaces, the floor standing machines produce a far greater airflow than the previous iteration – AM03 Pedestal generates nearly 50% more airflow at maximum than the AM01 Desk fan.

Dyson first introduced Air Multiplier™ technology in October 2009 offering the first real innovation in more than 125 years. Dyson's patented technology replaces fast spinning blades and awkward grilles with loop amplifiers. The machines draw air in at the base through a mixed flow impellor – a combination of the technologies used in turbochargers and jet engines.

Unlike conventional fans with limited settings, Dyson Air Multiplier™ fans can be infinitely adjusted up or down. The new tower and pedestal fans offer precise airflow and oscillation control and can be adjusted remotely. Air Multiplier™ technology is easier to clean and a safer way to keep cool this summer.

Both new fans come with a remote control, which is magnetized to conveniently locate itself on the machine.

"The new machines are engineered to circulate smooth un-buffeted air in larger rooms. They draw in and multiply nearly 50% more air than our desk fan," says James Dyson.

Dyson AM02 Tower fan specifications:

AM02 Tower is slender and running track shaped to take up limited floor space. Drawing in nearly nine gallons of air per second, the machine amplifies the air 16 times creating a smooth and cooling airflow.

Dyson AM03 Pedestal fan specifications:

Offering the most airflow of all Dyson Air Multiplier™ fans, the AM03 Pedestal takes in nearly nine gallons of air per second and amplifies the air 18 times. Unlike other pedestal fans, which use an awkward clamp to fix the height, AM03 Pedestal uses a constant rate Tensator spring to easily push or pull the loop amplifier to set the height and angle. The machine extends nearly nine inches for use in larger areas including living rooms and offices. It has no spinning blades, is easy to adjust and tilt.

How Air Multiplier™ technology works:

Dyson Air Multiplier™ fans draw air in through a mixed flow impeller – a combination of the technologies used in turbochargers and jet engines. Only 7% of the air generated by Dyson Air Multiplier™ fans actually passes through the impeller, 93% results from the inducement and entrainment of surrounding air.

Air is accelerated through an annular aperture set within the loop amplifier. This creates a jet of air which passes over an airfoil-shaped ramp and channels its direction. Surrounding air is drawn into the airflow in a process known as inducement and entrainment.

Conventional fans have limited settings. Dyson Air Multiplier™ fan airflow can be precisely adjusted up or down and oscillated by controls on the machine or remotely for the AM02 Tower and the AM03 Pedestal.
