AC Infinity Room to Room Fan 200mm, Two-Way Reversible Airflow Through-the-Wall Fan with Temperature Controller, Quiet Precise 10-Level Speeds for In-Wall Kitchen, Laundry Room, and Workshops, 8-Inch

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.

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.
