Review: Great product - Purchased this fan for inside of a jewelry studio, it works great with appropriate vent tube attached, have been using it close to a year now and it's wonderful, not much noise is created from it, I like the variable speed control, and have had it set up next to a laser engraver to pull fumes outside, and 10/10 better than any fan purchased at my local industrial shop
