This fan was fairly easy to install. It worked great once I got it all set up to keep the room I installed it in better ventilated. I did not come with everything needed for instillation, so just be aware, that wherever you install this fan, research what kind of duct work and vent or screen you may need for the fan to vent out of. For its size it pushes a good volume of air! I am pleased with it.

This was the solution to the heat and humidity in my outbuilding! Recommend highly.

noisiest fan in the entire universe

This can easily get air to a room that doesn’t air out well, or stays hot and stale. Especially if you have a wall ac unit in an apartment with multiple rooms. This is why I got it in the first place. The only drawback is that it is extremely loud! It drowns out everything and can easily give you a headache if on too long. However, it does work extremely well. It has a mini touchscreen operating panel on it. It can circulate air quickly, and don’t have to continuously run it.

So admittedly we're not using it in a crawl space, but rather in a Food Truck - so this review is based on our application. While the functions are very similar to it's intended use, this fan delivers more than we could of asked for in our little truck.What we absolutely love about this fan;1)It's Stainless Steel. In a foodservice application this is great as it makes it very easy to clean, it won't rust, and it makes the health department very happy.2)This thing runs quite. It's nice that it's not overly loud in our small truck, making it bearable to listen to.3) It puts out the air. It does a great job of moving the air out.4) It's adjustable speed. This is fantastic in our application as it's a simple as hitting a button to increase the fan speed.5) Controls - tons of options to change the settings and they are easy to understand and operate.6) Temperature display - An added bonus as we always know the temperature inside the truck. The added bonus of the auto function makes it nice at maintaining a consistent temp.7) Good looks - yes this fan is stylish and looks great inside our food truck. It has a professional look to it, thus keeping with the quality and style of our brand.We looked for years for a fan like this for our food truck and didn't want to spend $100's on one that was made for foodservice. This fan not only looks better, but performs better than the ones that we've seen in other trucks, and a fantastic price. You won't be disappointed with this product!

I live in an old home built in 1900. We are working on getting gutters but as you might imagine, without them the crawlspace is damp. This fan has dropped humidity from 75% at times to around 50%. The stainless steel design is a must and the fan noise is acceptable to me. I did have to run some romex and an outlet for power but that was no big deal. Mounting will vary by vent size and type. I had to drill holes in the crawlspace masonry for screws and anchors. As long as it holds up I recommend this vent fan.
