Customer Questions & Answers

Can this fan be used in a dryer vent duct to help move lent up and out?

Asked by: kriegmeister
Yes, the fan is suitable for that application.

Can this be used to remove high humidity air

Asked by: Arthur
As long as the humidity does not form water droplets on the fan it will work just fine. If the fan might get wet from condensation, steam, etc. then it would not be suitable for this application.

Does it only run when the furnace runs?

Asked by: DE
Hello, As it comes in the box there is nothing that switches it on/off. If you put power to it the fan would run continuously. There are a couple of ways of powering the fan. You can use our Ductstat, which is a duct mounted thermostat that senses the temp of the air in the duct and turns the fan on/off. You can also have an HVAC person wire the fan to be energized when the blower in your HVAC system is on. Feel free to call us at 800-999-3267 if you want to discuss specifics. Thanks, Suncourt

Customer Reviews

Inductor 4 in. In-Line Duct Fan is rated 3.6 out of 5 by 31.
Rated 5 out of 5 by from works just as expected This 4" in-line booster works just as it should for my 80 cf garden veg box, it keeps a nice amount of air moving out, more than enough to create strong a passive intake and keep the plants blowing. However this is not an in-line vent it's a booster, it's meant to supplement a regular inline fan such as a unit by fantech,sun leaves, vortex, etc. The only reason it works on its own for me is that I have a small enough space, as long as you remember that this unit is meant to be supplemental or can do the math for ventilation CFM requirements you'll be fine and pleased. The same goes for the 6 & 8 inch version as well, use as intended and don't expect a $30 booster van to vent a attic/room/crawl space when it would take a $200+ unit pushing a few hundred to a thousand CFM to do the job properly.

Rated 5 out of 5 by from 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 out of 5 by from 4 in. In-Line Duct Fan This is a bit pre-mature for this review, but the reason for that is the instructions say to add an inline 15amp fuse which it did not include. Wow, a 50 cent fuse, they could not include. I live 20 miles away from Homedepot and now I have to wait untill I get a fuse now. Why couldn't they just include the fuse. It's like buying a new car without the keys.

Rated 4 out of 5 by from Good little fan I'm using this fan to exhaust my cat litter box into atmosphere The fan is located about three feet from the exhaust air plenum, just the right distance to avoid any back air flow from the outside. I do recommend this fan for small projects and low volume ventilation.

Rated 2 out of 5 by from not 80 CFM The box says it will move 80 CFM. I have 50 CFM bath fans that move more air than this does. Don't waste your money.

Rated 2 out of 5 by from Ok Moves air, but very little. Kind of loud for the amount of air it moves.
Date published: 2014-10-08
Rated 2 out of 5 by from Poor speed, not worth the purchase. The speed on the duct fan is insufficient, this results in little to no difference when installed. If looking for a reasonable increase in performance I suggest purchasing a stronger unit.

Rated 4 out of 5 by from 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 .
