Query: Compact air pusher, white noise maker

This fan moves a lot of air for its size and is suprisingly stable due to its low profile and wide base. It does make some noise, but its been safe around the kids and easy to move around, even in the van (with inverter and 12V). On the highest setting, you can feel the air from at least 10 ft way. I would rate the noise as being similar to the vent fan on a microwave or Jenn air exhaust. Its enough to notice its absence when you turn it off.
