Suncourt ThruWall Room-to-Room Transfer Fan — Quiet Through Wall Vent Fan Improves Air Circulation Between Rooms 100-275 Sq. Ft. | 10’ Power Cord, 2-Speed (TW408)

Purchased this fan to get warm air from a hallway/main living area into a bedroom on the northeast side of our house. That room has two exterior walls and is always cold in the winter. Our house is heated with hot water baseboards, and this room seems to be on the end of the loop in addition to being on the coldest side of the house.Because framing around the door prohibited me from installing this fan over the door (and there wasn't any other wall available to go directly through), I had to install 8" rigid ducting that went from the hallway, through a cabinet in the adjacent bathroom, and into the bedroom. There's about 36" of ducting total. All connections were made using sheet metal screws and foil backed tape to ensure no warm air leaks into walls - which could lead to condensation and mold/mildew.According to the size/performance chart in the instructions, this fan is for is almost too big for the room (about 100sf). So I use the fan on low and left one small cap and one large cap on, as the directions indicated. I think having additional ducting actually works to my advantage, since the fan's ability to move air is somewhat diminished by having to 'pull' air through that duct. I don't have a traditional install to compare this to, but I will say that the fan is working fantastically for my bedroom. Warm air enters the top of the room and pushes the cold air back into the living area through the gap between the bottom of the door and the floor. The fan is plugged into a Lux Win100 thermostat so it turns on only when the thermostat calls for heat.The fan noise is very low, in my opinion. Just gentle white noise.Dings -- Installation instructions. The instructions make it seem like utmost precision is required when cutting holes, but that's not really the case. I wouldn't advise anyone to be purposefully sloppy, but a little a little slop is ok.- More importantly, I was not impressed by the way the inlet cover is supposed to mate to the flanged sheet metal sleeve. It looked like the flange was supposed to mate with the plastic housing, but the sizes don't match. So you're left just kind of 'making it work'. That's not the end of the world, but some kind of snap fit would work much better. I almost took a star off for that, but it's not a performance issue.All in all, this is a fantastic solution since it works great and it's way cheaper than buying and running a space heater.

The fan is the perfect size to replace a fan we have had for years. Perfect size as advertised. Fairly easy to install and works great. Love the two speeds of the fan Fast delivery. Good product

Definitely a game changer bought for my sons room to help bring heat from the living room. We have a gas heater in living room and was using and electric heater in my sons room. Works great whatever temp i set the living room my sons room becomes in a matter of minutes. We took the electric heater out of my sons room it is completely unneeded now. Only complaint is i was it had 3 speed settings with one lower speed so it would be quiter. We only use speed 1 and its more than egnough. Its not loud but not silent either

The media could not be loaded. Working good so far.Easy installation.Long power cable.Low noise.Good flow of air.Will recommend.

So this was bought in July 2021 with the intentions of having cooler air from one room make its way into another room that doesn’t have air circulation. I installed this per the directions with no complications. Everything went well and I even set it up on an outlet timer so it would run in 1.5 hour increments (since it goes into my office). The reason for 3 stars is because it started off working really great. It’s quiet and powerful enough. But - it started making noises as it was turned off. I noticed a small washer inside the unit that would spin and when it slowed down the washer would rattle. Very annoying. Now the item hums. So, I placed an order for replacement. If the new one comes in and works for an amount of time that I am satisfied then I will adjust the stars.

I installed this unit between our living room(free standing fireplace) and the master bedroom. When the fireplace is running the bedroom gets a little chilly. The unit does a great job transferring the very warm air(78 - 80 degrees) from the ceiling to the bedroom. I continue to experiment with the various air restrictors to see what works best. The restrictors are easily removed and mounted on either side. While it has two speed settings, I only use the low setting. Our bedroom is around 196 square feet with sloped ceilings. Prior to using the fan the temperature used to be hovering around 66 degrees if the fireplace was running. Now it is in the low 70's. The noise is not too bad....kind of a nice white noise if you like that kind of thing. I am experimenting with the larger restrictor on the outlet side which is supposed to help a bit with reducing the noise. All-in-all, it works great!

Unit was very easy to install and works great!!

Purchased this to mount in a basement wall to move warm air from one room to the other. I was able to put the cord and plug on the opposite side if the room that was finished. The fan is loud on high but, it also moves a lot of air. The lower setting is quieter and moves less air. Even spray painted to blend better with the wall color.
