AC Infinity Room to Room Fan 200mm, Two-Way Reversible Airflow

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'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.
