So…this uses a smaller diameter fan in the base and channels all that air up and out of the ring? All of that to remove “buffeting”? I personally am not able to tell the difference of the air hitting me from a fan compared to normal wind (ignoring that the fan is very localized).
Other than that though, from my experience with cooling fans for computers, in general, smaller is terrible. They have to rotate much faster to push out air to even come close to the performance of larger fans. Because they have to rotate faster, their bearing system tend to die a lot faster.
So, in the same principle, this small fan seems to me like it would be far less efficient, and more likely need replacing sooner, than a traditional fan that’s the size of the loop on top. And for the price of these things, WTF?!
Does anyone know what the life span of these are? And are they trying to figure out what to do with defunct fans/motors that didn’t make the cut for their vacuums or something, so they came up with this idea? Kinda like how with the chip market Pentiums don’t make the cut for Extremes, and Celerons don’t make the cut for Pentiums?
