Suncourt TW408 ThruWall Room to Room Transfer Fan, Quiet 2-Speed Wall Mounted Plug-in Fan with 10 Foot Power Cord and Installation Kit

Works well

We ordered 2 of these fans to install in the walls between some rooms in our basement. It is surprising the amount of air they pull in. The fans are also very quiet. I highly recommend this product.

Bought one of these, installed it and when we turned the power on, the fan inside the unit flies loose of the motor shaft. Called Suncourt and they tell us to return it because this sometimes happens. Second unit arrived today and re-installed. Again, turned the power on and the same thing occurred. There is no glue or fastener between the fan and the shaft on the motor. Really poor design Suncourt.

I wanted to use this thru the wall fan to help distribute the heat from the adjacent room where my wood pellet heater sits to the living room. I would say if you are sinsitive to noise this is not for you. On high setting it is very noisy. On low it barely moves any air. We have to turn up the TV volume just to here it over this fan. Also it is too weak to move the heat around. I decided to remove this fan and custom made my own fan using a 200mm computer cooling fan. This setup moves twice the air and super silent to the point I have to look at it to see if it is still on. Also now moves the heat around the house much better. In my opinion I would not recommend this item.

It works great moves a lot of air.
