Excellent installation instructions. Small, quiet and add quite a bit to dehumidifier efficiency.

This fan took care of the smell problem and was easy to install. Thanks

I purchased the 2 pack and was delivered with the rest of the order. Appears to be a quality product. The shortfall is that I’m not too bright. The drawing is confusing to me and I’ve never seen connectors like this. I’ll figure it out and hope to be able to provide a better review.

Long story, short, but... Following my DIY crawlspace encapsulation job, we started noticing an odor in the house. At first it was just a whiff, but as time went on it got stronger and stronger. Smelled like cat pee and I was wondering if the previous owners had felines in the house. I called Larry at Crawlspace Concepts and he said the culprit was likely soil gas and that I should install a 88 mitigation fan and slide a bunch of perforated pipes under my new liner. I took his recommendations, installed the system and within 24 hours the smell was completely gone. With the fan and pipes it was another $350, and I had to pay a roofer $200 to install the vent on our steep roof.
