AC Infinity Room to Room Fan 8”, Two-Way Reversible Airflow

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.

This is a great product. Good documentation, everything needed to install the fan is provided in the box, and it is incredibly quiet at low speeds. My only gripe is that people looking for a simple on/off fan might be annoyed by the number of button presses required to cycle between the "on" setting and "off" (it has to cycle through every mode/setting that the device has). But on the upside, the fan is reversible and it will remember the setting every time you turn it back on from that point on. Tips for installing in drywall: 1) After you've traced the circle using the provided template, you can easily cut the circle out using a cordless drill with a small drill bit attached. Just drill a hole into the circle border and trace around the circle. Screw in something on a string to the circle center to be able to retrieve the plug if it falls into the wall as you complete the circle, if you care about that sort of thing. Use a sanding drum on the drill to enlarge the hole as necessary. 2) For the second side of the fan (the non-display side), cut the hole smaller than the template suggests, as there's a good chance that where you drew the hole doesn't 100% align with the first side. Once you see where the first side aligns, you can use the sanding drum to enlarge the hole in the appropriate directions. That way, you'll be guaranteed that the two halves mate up perfectly. In the end, don't worry too much about having the hole exactly the size that it needs to be, as the face plate will cover the edges, much in the same way that an outlet face plate covers the whole cut for the electrical box.

excellent fan quality. I”ve been running it without incident for over a year. The only reason I didn’t give it a 5 star rating is that it’s touchpad interface is very confusing…even when consulting the instructions. It’s not exactly intuitive to operate. Very quiet to operate.

I installed this fan to pull out hot exhaust air from my computer closet. Initially I was worried that I'd have visible controls facing into my office, but because this fan can be programmed to run in either airflow direction, I was able to install the fan with the controls inside the closet. The end result is a very clean aesthetic, in my opinion. Don't take my comments about temperature control too seriously - I run the fan in continuous low-speed mode, and it works exactly as I had hoped - my closet is only ~1 degree warmer than ambient, despite having ~400W of computers running continuously on the floor of the closet. In the fan's low speed mode, it's essentially silent. I don't use the higher speeds, because the low speed is sufficient for my cooling needs. I gave this fan a five-star review despite it being not the easiest to install. Install is a one-time thing, and if it takes an extra hour to install vs. another fan, so be it. It was a little challenging to cut two separate circles on opposite sides of a wall, and then to position the two sides of the fan in perfect alignment, but the effort was on par with many other typical "homeowner can do this" tasks. I would have also preferred that the electric cord was a bit more substantial, since I wired it to the hot side of my closet light switch. The supplied power cord is relatively long, though, so even though my fan is ~6' away from the power switch, I was able to use just the fan power cord to reach the power switch. TL;DR - it takes longer than you might expect to install, but once that's done you will have an effective fan that operates nearly silently at low speeds.

I have that one bedroom where all heat collects. I purchased this fam to blow air out of that room at ceiling height into the main room that has a ceiling fan that moves that hot air down to where the house thermostat is. Before installing this fan, the room was unusable without a huge fan at the doorway - and even then, it was barely usable. With this fan installed and running on medium speed, the room is warm, but not unberable. The air conditioning turns on more often, but doesn't run as long. Overall, it keeps air moving around the house and inhibits that pocket of unbearably hot air. Installation was as easy as could be expected. The instructions suggest doing the outside of the fan first, but I had to do the inside first. The only issue I had was trying to perfectly align the holes on each side of the wall. The inside hole is nice and snug. The outside hole is a little larger than it needs to be because I had trouble getting the two aligned. When it is all put together, you can't see the holes at all, so it doesn't really matter. We are using the plug going into an outlet below the fan. It says it can be hard-wired, but that isn't very reasonable. The junction box inside the fan is far too small and it needs a grommet for the incoming wire. You could hard-wire it, but you shouldn't if you want to keep your electricity up to code. Noise is the big issue. We were using an 18 inch floor fan to pull air out of the doorway. It was very loud and didn't keep the room cool. This little fan is quiet enough on medium speed (5 out of 10) that it doesn't bother anyone. On 10, you can hear the rushing air and it an annoyance if you are trying to listen to TV or a video nearby. With it on 5, we haven't had any problems. It has been installed and running for a week. Hopefully the unit lasts a long time.

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).

I haven't installed this yet, but it seems very straightforward. I plugged it in to ensure all the functions work, and they do. I am especially excited to find a fan that can reverse direction. The other room to room fan I was going to buy was going to be over $300. That one had the benefit of the inlet and outlet vents being offset, which preserves privacy and prevents light coming through, but the price and extra features on this fan totally make up for it. This fan has everything I wanted that the other fan didn't: option to plug in to regular outlet, reversible fan, and a thermostat. And it was over $200 less! Other benefit: 10 fan speeds vs. only 3 speeds on the more expensive fan. Probably lots of others I haven't figured out yet either. I really don't want to deal with wiring this unit directly but also don't want to see the cord, so I found a wire cable pass-through receptacle that I plan to install down near the outlet and directly below the fan. I will drop the plug down into the wall and pull it out of the pass-through and simply plug in. So that's an idea for anyone else who is bothered by seeing the cable.

Initial impressions are this is a high quality fan. It has a few different ways you can program it, which is nice. See the manual. It would be nice if it had a remote. It moves a ton of air, but that comes at the cost of noise. It's not an annoying fan, just loud as it's moving a lot of air through an 8in metal shroud. I have a network rack and servers in my office, which generates a lot of heat. It's fine if my door is open but when closed, it gets almost 80 degrees. Above my rack is a jump duct that goes to my kitchen so I put this in place of the vent cover that was there. I made a cover from 1/2 plywood and attached this fan. Level 6 is as high as I can go as that is 40dB. I have it on a smart switch, which turns off the fan when the AC is running as to not suck all the cool air out of the room. Then it turn on 1min after the AC stops.

I struggled to find a fan which could transfer cold air from an adjacent air conditioned room to my very hot music room. This does the job brilliantly. It is quiet, well made and easy to install. It doesn’t have to be hard wired. Although it is American, It works at 240v - it has a 3 pin plug. It’s solved the problem I had with an uncomfortably hot room.

Fungerar mycket bra! Ju högre varv desto högre ljud, men inget man inte kan stå ut med då det kniper.

Great little fan. Intuitive controls. Easy to install, though I must say do not drill and hammer in the drywall anchors for the front end when the manual tells you to, wait until you get the back plate in it's final position slide the front one in and then Mark your holes, take it out, drill the holes, hammer in the anchors and it should be good to go. Is really quiet and good power on medium settings, well the maximum setting is great for someone like me who actually enjoys a bit of white noise.

Best Automatic Control Room to room temp regulator

I live in a split-entry house in Canada. I installed a pellet stove in my lower level family room two winters ago and relied on convection to move the heat from that room, down a hallway and up into our main living area. However, I found the lower level room would get very warm before any benefit was felt upstairs. This fan is a game changer. I installed it high on the wall between that room and my entryway, bypassing the hallway altogether. I had an electrician tie it in to an outlet that was located in the same wall cavity. The thermal probe is on the hot side, and comes on when the temp is above 73 deg f. Now the lower room doesn't get super warm because the heat is exhausted to the rest of the house much quicker. My entryway was always the coldest space in my house, but now I don't feel a temp difference walking through it to get downstairs. Upstairs is cozy warm, and my baseboard electric is rarely coming on. I really hope this fan will last for many years. Great product!
