Room to Room Fan 8”, Two-Way Reversible Airflow Through-the-Wall Fan with Temperature Controller, Quiet Precise 10-Level Speeds for In-Wall Kitchen, Laundry Room, and Workshops

Impressive packaging, included a very robust cut and drill template for mounting the unit. I would have expected a folded up piece of paper for the drill guide but nope, it included a very sturdy plastic template. Instructions where easy to follow. Programing the unit was intuitive and easy. Best of all it really does move some air. I installed it in a wall between the basement and middle level of our tri level house to move hot air from our fire place into the middle level where it can get cold. As soon as the temperature warms to 72 degF the unit turns on and pulls air from one room to the next and turns off if the temp falls below 68. It just works beautifully!

My install is a little different than most. We built this custom enclosure to house the fan, we are using it to circulate dehumidied air coming out from the far end wall of the basement and across the entire space, creating a loop of fresh dehumidied air. This unit was a key design part for the air circulation. The supply and and return of the stand alone aprilaire install are on on opposite sides of the room of a large L shape basement. I tested this and it works flawlessly. Excellent fan, quiet, powerful. Can be set to continous or timer or whatever you want.

Nice design and easy to install. I use the fan to move hot air from my wood insert to the rest of the house. I use the feature that automatically turns on the fan and then incrementally speeds up the fan as the temperature increases. Works great.

I extended this with 8" ducting to push air through the depth of a closet, not just a single wall. It seems to work well. My biggest deciding factor for this unit was noise level (low except on higher speeds) and that the fan blades & motor work effectively in either direction. Being able to move warm air out in warm seasons and warm air in during cool seasons with a single unit is a huge plus.

This is a great product. Super clever and well-designed. It’s not too difficult to install, and I love that although it comes with a cord to be plugged into an outlet, you can unscrew a little plate where the cord enters the unit and remove it to reveal terminals for permanently wiring it through the wall for a much cleaner installation. One thing to note about the installation that would be easy to miss and cause you huge frustration. There are two plastic templates to use for marking/cutting holes in the wall. They are nearly identical, so it would be easy to think that they are identical. THEY ARE NOT!. If you make the mistake of just using one of them to mark both sides of the wall, your holes will not line up properly. Make sure to use the front one for the appropriate side and the back one for the other side. Beyond that, the device functions exactly as you would expect. You can set the threshold temperatures that will trigger it to come on, and then just forget about it. Or you can operate it manually. It’s super well-designed. Also, it looks about as nice as something like this can look, I think. No complaints at all.

This is a nice unit. Looks good, can move a decent amount of air, lots of power/speed settings, has good mounting hardware, instructions, and templates for installation. Compared to another cheaper through-wall fan I've tried it's quiet and vibration-free. Pretty much what I had hoped for all along (the previous, cheaper unit was...disappointing).

Excellent high quality room to room fan! Cools down room quite quickly! Definitely worth the price and works very well.

I'm writing this from the perspective of a person who is handy around the house, but has never cut any significantly large holes in the walls of his home before, and certainly not TWO significantly large holes in between 2 very important rooms in said house before. If you're THINKING about this as an option, like i did the first time i saw these, you're gonna wanna read this: If you're not a contractor and are familiar with how to measure something like this out and how it works, this is designed to connect TWO rooms and to transfer air from the warmer room to the cooler one, or vice versa in the summer - if you have a (non ducted) heat pump, say...in the front side of your house, but it doesn't heat/cool the back side of your house, you want one of these and yes, you want to cut some big holes in your walls to connect the airflow in between them. you know how they say 'measure twice, cut once'? yeah you're gonna wanna measure like 30 times and make EXACTLY sure the front and back templates (which are provided with this model, but not others) line up. I'm pretty smart and i really had to wrap my brain around the 3D aspect of this. to make it even more complicated, the walls in one room don't terminate at the same place as the other room, so measuring 'to the far wall' was out of my options list. i ended up measuring to a stud (with a stud finder), and then marking and measuring from the nearest one and i STILL didn't line it up exactly. not only did this happen with the first one, but it happened with the second one as well. maybe i'm just terrible at measuring? who knows. once you get the holes lined up, getting the fan in is super easy. give yourself a little extra room on the hole templates. err on the 'outside edge' being a tiny bit bigger, as if you get too close it'll be tight getting both sides to line up. after that you just join the outside to the inside piece and you're done. screw them into the drywall and thats it. i went with the wire going down the wall, as i didn't want to hard wire these. the fans are QUIET until you get past 5 (it goes from 0-10). i have the one in my bedroom at 3 and the one in my hallway at 4 and you can barely hear them. people seem to complain about the complicated nature of the 'features' but they're pretty simple. for example, i choose to use 'cycle' mode. this has 2 modes, cycle on, and cycle off. if you want your fan to run for 45 min and then turn off for 30 min, then repeat the CYCLE, you go to 'cycle on' mode, set 45 min, then hit the button again to get to 'cycle off' and set that for 30 min. easy as that. we're just so used to things being 'app easy now' that we maybe forget how to follow directions. yes, i was confused at first as well lol. to determine 'what' speed it will spin at in any of the modes, you just go to the 'on' setting and set it to whatever number you want it to spin at. if you say, '3' power, every mode, once enacted will spin at 3. in summation, in the winter, the front of my house is a steady 68 degrees with the heat pump on, and the bedroom is like 61, and the even further away studio room is like 60 degrees. with the fans on, in cycle mode, average temp in bedroom is 66 and studio is 65. that's a really healthy adjustment. when we turn the stove on to cook those fans pump all that really hot air all the way to the back of the house and make it feel like we had the furnace on. can't recommend these enough. it requires some thought and work but you can really change your house temperature and save some money with these. i'm certain when we cool the house in the summer it will have the same effect.

Well made fan that fits out interior wall perfectly. Good instructions and the electronic functions work well. Very quiet operation.

facile à installer...suivre les instructions à la lettre toutefois...surtout pour la position du perçage des trous de vis qui diffère pour l'avant et l'arrière...les deux tubes s'insèrent parfaitement l'un dans l'autre... très SILENCIEUX !!! permet la circulation air frais du climatiseur de la chambre principale vers la chambre secondaire... SATISFAIT ...totalement !

Very high quality. Installs very nice. Very high quality fan. Controls are amazing and works well. Used a kasa plug to remote on and off. Too bad this fan does not have a wifi connection with app. Better to charge more and make it so.

In my north region it took 1 month to receive this product (from USA). I installed using its template via between 2 x stud walls with drywall on each wall surface. Slow process to install but if one takes their quality time, its an easy install. For me, I used a Plug-In method - which had near floor level electrical outlet beside it. For my simple technical skills, its front panel controls are "way too complex". I would like a simple OFF/On, Forward/Reverse and up/down fan speed controls. All the other fancy temp settings, timer settings, etc. is "too much". On a good note its spinning fan is super quiet - which is the main reason I bought it. And yes, it does move lots of hot air from our living room (with gas fireplace) into our master bedroom. I'd buy again but wish its 10 speed motor controls were less complex.

Wish these were a bit cheaper, its a great bidirectional fan
