AC Infinity 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

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 have been using these in my basement for over 1 year now to transfer air from room to room. They are still working great, very quiet also

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!

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.

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.

Great product. Company from CA. Comes with cord and can be hardwired. Easy to install with great instructions. Customer service was very helpful. Reversible air flow is fantastic and worked great. Solid build. Was very impressed. 10/10, ended up ordering their floor vent too.

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.

Needed to cool a room with no vents, goes a good job, can be a little loud on high settings, but it is in the kitchen area for me so not a area that is quite to begin with. Does good job so far. Recommend.
