Review: Súper genial funcional muy bien
Review: Exact replacement motor. - I recently bought an exaust fan for my roof. Even though it's a new unit, in the future I'll have to replace the motor. I bought the exact same motor on desertcart. It can be a real pain finding a motor after it fails. And a lot of local dealers wouldn't have an exact replacement motor. And then they will have it special ordered which is going to add to the cost even more. And I mean the motor is identical from the name, speed, mount, and wiring. And the price couldn't be beat. And I got free shipping. I hate to think how much running around I would have had to do to buy it locally.

### ⭐⭐⭐⭐⭐ Reversible fan, had it the next day and worked as expected.
*by J***E on August 14, 2024*

Fan worked well, as expected. No problem reversing the fan direction. Fan can be mounted in multiple configurations if needed.
