Favorite fan

It's a Duracraft with one set of large blades, not one of those less tall ones with two sets of much smaller blades. It moves a lot of air. And it's quiet. We bought two at the time, probably over a decade ago. We should have bought more, because we've never seen them again. Last summer, we thought one had quit working. When we were searching the sleeping porch for more fans this weekend, we found the large one not used last year and brought it out to try one more time before disposing of it. The control had been lodged between intake and exhaust. It works perfectly well. Even though it has been in service for just one year less than the other one just like it, it's clean. The one used last year is filthy. This is just another indicator of the drastic change in Austin air quality over the last year and a half or so.
