This fan sure does move some air. I have a grinding cupboard/nook in my workshop where I make knives. Although keeping the grinder in a small closed in space works great for keeping metal dust in one place, as soon as I grind handles I get fine wood dust everywhere.
I installed one of these fans through the wall and now all the dust is simply sucked out of the workspace.
Make sure if you are getting one that you have a solid wall to fix it to. Unfortunately, I had to mount mine to a plywood wall that doesn't have the greatest framing behind it and as a result I do get a bit of vibration noise. It's no fault of the fan, just a caution if you aren't installing somewhere solid.
For under $70 this thing is a beast.
