Expectations met

" The fan works as expected without an excessive amount of noise. Keep in mind that the temperature sensor on the unit is not flush with the mounting surface. It protrudes a bit and does not allow for flat mounting on a surface that only has a hole in it for air. "

Inexpensive and Does the Job, Just a Bit Noisy

" The fan works just fine and provides very adequate airflow in a cabin crawlspace. It was easy to install and wiring was simple. It is less expensive than other alternatives I have seen. If you aren't competent with wiring it will be a small job for an electrician.
One minor negative, I was surprised that it does make an audible humming. Not loud but it is noticeable in the quiet environment of the cabin. Because the fan itself looks so much like the cooling fans on electronic equipment cases I had expected similar sound level. Not really a problem although if it was installed anywhere near a deck or patio it will be distracting. "

" We have a small crawl space under new addition construction that has stayed wet due to unusual amounts or rain and inability to get grade work finished. This fan has worked non-stop for 4 months, so far, and helped us keep the moisture level down. "

Works well!

" Put the fans in about 2 weeks ago, really easy to wire up and install. So far they are working really well, much less moisture in our crawl space.
Northern sells the fans cheaper than you can purchase them from the manufacturer's website.
