18" Heavy Duty Exhaust Fan is rated 5.0 out of 5 by 1.
Rated 5 out of 5 by from Works better than expected!! I recently built a 30' x 48' metal building and put the epoxy on the floor which caused a serious moisture issue. I purchased the IF18 fan and installed it in the gable on my building. I turned it on at 7pm and by 7am the interior of the shop was completely dry! My floors looked like someone sprayed them with a water hose and this fan completely removed all the moisture within 12 hours, I would highly recommend this fan to anyone. The product was assembled very well, runs quiet and performs flawlessly. I'm going to add the Duostat that Ventamatic offers to accent the fan as I live in Jacksonville Florida where both temperature and humidity can be a challenge.
