Customer Reviews
The Tjemlund UnderAire Crawl Space Ventlator is very easy to install and very quiet, but it moves quite a bit of air for its size. It has a sturdy build and can be trimmed to fit your vent if needed. I did not have to do any trimming at all, it fit my crawl space vents perfectly right out of the box. I was having a problem with the humidity in my crawl space until I installed the ventilator, now the humidity problem is gone. I also like the feature that you can set the humidity level to the % that you desire. Once the humidity gets below your setting the fan will cut off automatically, and then come back on if the humidity gets above the level that you set it on.
