Dyson Cool AM07 Air Multiplier Tower Fan Review

Dyson Cool AM07 Air Multiplier Tower Fan ReviewIf you have read any standing fan reviews, you have heard of the Dyson Air multiplier fan. Ever since these came on the market, they have been a topic of discussion for everyone from manufacturers to users alike. One thing that most can agree on, however, is that they do work, and very well at that.

Product Overview

The Dyson fan uses a patented system called the Air Multiplier to deliver a powerful stream of air without using blades. The lack of blades means that the fan is safe to use around pets and small children because there are no exposed moving parts for them to be injured with.

This Dyson fan has a lot of features that most shoppers look for in fans beside the unique aesthetic. There is a timer that allows you to set an operation time from 15 minutes to 9 hours. After that, the fan will turn itself off automatically.

There is also a full function remote which can be stored on the fan itself when not in use. The actual controls for operating the fan are located on the base which is the only place they could be fit. They are easy to use, but for the most part, the easiest method of control is with the remote.

The fan also oscillates a full 90 degrees, which means you can place it near the corner of a room and have it cover the entire thing without adjustment. At its highest setting, (and there are ten different levels of power), the fan moves about 1200 cubic feet per minute. That’s astonishing considering the only actual fan is the small one in the base.

This fan is also fairly quiet, generating a scant 60 decibels of noise during full operation. For comparison, that’s about as loud as a library should be.
If like us, you’re curious how the Dyson works, read on. We delved into the mysteries of the Air Multiplier to see how it works exactly.

How the Dyson Fan Does its Magic

There’s a pretty neat YouTube video by Dyson that shows how the Air Multiplier works, and the graphics and soothing voice do a fairly good job of explaining things and how the Dyson fan stays quiet. But how does that tiny fan in the base cause such a large air output through the fan?

Essentially, this is how it works. The small volume of air is forced through the small opening in the Dyson fan. Air has a property known as entrainment, where it attracts other air particles and makes them move with it. So when the Dyson fan shoots air out through a small opening, the air is coming out at a tremendous relative velocity.

At that high rate of speed, it comes from the smooth surface of the fan into the rough and tumble world of the surrounding air. And there, it grabs onto, bangs into, and pushes other air molecules along as well. That small stream of air then jostles a larger volume into moving. And because of the shape of the fan, that is, the large oval, the fan is able to focus that air flow right into the center where it can pick up and move the most amount of air possible.

So there you have it. By taking advantage of the physical and fluid dynamics of air, Dyson was able to create a fan that seemed to magically create air current where there was none previously. There are several physics papers that explain the workings in much more depth if you’re interested. You can read one here to see some very interesting diagrams about it as well.
