Rated 4.0 out of 5.0 by engineer simple design, low cost
I used this after the blower fan on my wood stove quit working. I made a flange out of a 4" elbow and attached it to the back of my wood stove (where the blower attached) , attached a strait piece of 4" through an interior wall to a room that was always cool, then I attached this duct fan. So I use this to move cool air out of that room through the wood stove, in turn warm air gets pulled through two rooms and keeps everything comfortable. It does not move a lot of air but just enough to do what we need. Next step , attach one to a range hood mounted over the wood stove and duct the warm air to another part of the house .

Rated 3.0 out of 5.0 by Robert Quiet but underpowered
I have this venting an enclosed cat litter box, wired to a motion detecting light switch mounted in the box. When it detects the cats in the litter box, it turns on the fan for about 5 minutes then shuts it off. It is very quiet, however it is barely powerful enough for this small job. The flaps on the outside exhaust vent barely lift when this fan is running. I had to purchase a metal wiring box separately and mount it to the metal duct portion of the fan. They should have included that. I am considering whether to return it or not, and buy a more powerful one. But it does the job, there is no more litter box smell immediately after the cats do their business like there was before, so I may just keep it.

Rated 5.0 out of 5.0 by okeah1 Awesome fan for cat's litter boxes!
This is a great stink away product! I moved in town house 4 years ago with 4 cats. In the basement made a toilet room out of the closet. Very quickly 4 cats and 2 litter boxes stunk up all basement. I bought this wonder fan install it in a 4" flex hose and ran the hose to the hole I made in the house right above the ground behind the bushes.
This fan is been on 24/7 since then (4 years!) and there is absolutely no smell in the basement. I will buy another fan soon just in case the old one quits. It is a definetly mericle fan, very quiet, slow speed, but gets rid of all the stink from the closet! Awesom little bugger!

Rated 3.0 out of 5.0 by HighHopesGuy Sufficient duct fan for low volume
solid fan but with very weak flow so not too effective in pushing air through duct if a high volume is desired.

The fan is low cost, but no power what so ever, and the plstic propels, make them difficult to put them close to the heat.

Rated 2.0 out of 5.0 by Freightdoggy Does not move enough airt
Purchased this little 4 inch fan to continuously vent out my crawl space. During the summer time when the air was cool and more dense inside than out, it moved just enough air to be noticeable out of my crawl space to keep it dry and fresh. Now that it is the winter time and the air outside is more dense than the inside air, the air flow has reversed even with the fan running to oppose it and outside air is flowing into my crawl space. I know the fan is not designed for this but thought I would give it a go. Recently I took this little fan out of my crawl space and installed a bigger fan that appears to be working much better. The little guy is now hooked up to my fireplace to push some warm air into the room and it works OK for that.

Rated 4.0 out of 5.0 by Vasparrow GOOD FOR BASEMENT EXHAUST FAN
I used this inline fan as the basement exhaust fan to discharge bad air from gas furnace, water heater, etc. I set an electronic timer to keep quiet during the night. It consumes little electricity but does wonders to keep the basement air clean. Every household should install an exhaust fan such as this one to improve indoor air quality. Most homes are so airtight that bad air is trapped inside and family members, especially babies and elderly, suffer numerous breathing problems. This condition potentially leads to cancer incidents.

Rated 4.0 out of 5.0 by midloman good if you don't mind the noise
This fan moved the air fairly well, but was to loud for my application.
