8” Two-Way Airflow Through-the-Wall Fan with Temperature Controller, 10-Speed Quiet In-Wall Vent Fan for 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!

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 !

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.
