Question: Can anyone tell me the diameter of the fan cage?
Document: Lastly, the switch on the back is large and easy to grab even in the dark. Overall, this fan packs as much power as I think anyone would need for home use, and is more compact and quieter than cheaper fans of larger size. No, it does not have an oscillating feature that will inevitably wear out and no, it lacks a remote control, but it does what a fan is supposed to do - move air.
Time will tell. Haven't had it long enough to say how it will hold up. Could move more air for the price but if it holds up better than the one before it I'll be happy.
Saves me money! I am truely impressed with this fan and would not hesitate to buy another if need be.
As previous reviewers stated, this is a solid fan and is just about the right size for my bedroom. However at the lowest speed it is noisy.
This fan has a lot of power but runs quietly. No regrets. I use it after showers to dry the steam in the bathroom and use it on carpets after shampooing them.
After 5 days of use we gave up and ordered an Air King 9214 which has performed perfectly out of the box. It's disappointing because a 12&#34; fan would have been sufficient.
Very pricey fan, well built and you won't break it!Others say no vibration, but I am getting 1 or two pulses every second, it is quiet, and the blades are true you can see zero wobbling of the blades when the fan is on!
I bought this fan as a replacement for a convection fan on a combustioneer stoker fired space heater.It works however when the fan is set on speed #1 and #2 it emits a obnoxious ringing sound. I will see how it holds up.
The Vornado fans I have had and I considered replacing with this model create a turbulence that spreads out from the air flow and are more effective for the same size fan at a similar cost and don't shake like this model. I may send it back for another and hopefully it won't shake.
It gets the job done in a way , I read all the reviews and I wazz expecting much more power but for the size of this fan " little" it's pretty good but if your the type of person that gets hot when sleeping I will strongly recommend to get a biger one
Answer: About 13 and 3/4". That's literally the cage. If you go from where the stand attaches on both sides of cage it's about 15 and 1/2"
