  • Balances temperatures in adjoining rooms, quietly and efficiently
  • Easily move the heat from a fireplace, or cool air from a window air conditioner, to an adjacent room
  • Great for venting rooms that always seem stuffy or smokey

Essential Info

In every home, there always seems to be at least one room that's always too hot or too cold. Regulating the temperature in that room is now substantially easier with the Room-to-Room Fan, a two-speed, in-wall ventilation system that moves heated or cooled air between rooms. This built-in solution is ideal for balancing room temperatures for maximum comfort, even in parts of the house that aren't getting their fair share of heat or cool air, like garages, enclosed patios, workshops or add-ons.

Flexible Installation
The Room-to-Room Fan is built with a telescoping feature that allows it to accommodate any normal drywall or paneled stud construction wall from 3.5" to 6.5" thick. The air discharge is on the cord/switch side (one-way air flow). The fan tube diameter is approximately 8". Grille diameter is approximately 9.75". Weight: 5 lbs. Power is provided through a 10-ft. power cord with a grounded plug (use of extension cords is not recommended).

Two Speeds
The Room-to-Room Fan has a High-/Low-Speed rocker switch, with a Center Off position. At high speed, it moves about 200 cubic feet of air per minute (CFM) and uses 60 watts. At low speeds, it moves about 125 cubic feet of air per minute (CFM) and uses 50 watts.

Quiet Operation
Sound levels are 51dB on high speed and 49dB at low speed — about that of a desktop computer fan.

Extremely Safe
The Room-to-Room Fan has been rigorously tested to ANSI/UL Standard 507, and is ETL Listed. The housing is made of galvanized sheet metal, with grilles made from high-impact, flame-retardant ABS. The electric motor is a Class B, thermally-protected motor.

    Wanted an in wall fan to replace 50 year old predecessor for moving heat from above stove to back rooms. House is 1500 sq ft and this works very well. Seems to be very well made. Thanks!
    Joe -- Pa.   12/14/2013
    We have a garage that was converted to a bar/pool room. but had no heat. We installed a pellet stove which works great, but the high ceiling trapped the heat. I just installed this fan to move hot air to a bedroom. I just wish there was a cover that could be put on when not in use. That way the noise from the pool table and bar could not be heard through the fan area. Other than that I would say this fan was a great purchase.
    JEAN N. -- sodus, NY   11/21/2013
    Love it. Looks great. Almost quiet. Very good quality.
    GEORGE A. -- portland, OR   11/9/2013
    Looks and works as expected and wasn't too loud. Cord looks funky clipped to the wall on the way to the outlet but plugging in the fan instead of wiring it was a plus in my case. The fan had a quality look to it.
    ROBERT -- dingmans ferry, PA   10/24/2013
    I haven't had to use them. But they are well made with nice looking grills. Grills can be painted to match any color. I'm looking forward to using them this winter. You need some basic carpentry skills to install the unit nothing complicated. I'm giving 5 stars even though I haven't had a chance to use them. I have used similar items in the past and these are better quality so I don't see a problem.
    BLUE SKY -- corvallis, OR   10/20/2013
    works great!
    EDDIE T -- carthage, NC   8/11/2013
    Very nice unit, easy to install, would highly recommend to anyone. Thanks
    JOHN H. -- poplarville, MS   8/8/2013
    This is a very good fan. It arrived promptly and in good condition. It was very easy to install. I just cut a hole in the wall and slid it in, secured it with a few screws and it was installed. It took less than 30 minutes. It runs very quiet, I can hardly tell it is on. I use it to push air conditioned air from one room to an adjacent room. It does a good job. It is a good product and a good value.
    MIKE -- chattanooga, TN   2/8/2013
    Works Really Well.... Using it to cool a small server room. Quiet and moves the air well.
    FRANK -- windham, NH   1/11/2013
    Great fan. I permanently installed it between large family room with high vaulted ceiling and upstairs hallway. I force cold air from upstairs into the family room w/ wood pellet stove. This keeps the room from getting too hot plus over pressures it forcing more hot air to go into kitchen and eventually up the stairs to 2nd floor. Unfortunately, I had to go between two walls (through small bedroom closet b/c upstairs hallway did not reach family room wall). Had to connect the two holes w/ 8" round HVAC sheet metal tubes. Also permanently connected power cord to back of 110 VAC outlet and drilled through one 2"x4" stud and added a fan speed controller switch with low/med/high. Fan comes with two speeds low (black wire) and high (red wire). I connected red wire to hot wire (black) from fan speed controller. Works like a charm! Now I have heat for entire house from wood pellet stove and don't have to depend on expensive propane for heat.

    Great Product. This was a replacement Item, the previous one worked almost continuously for close to 7 years.
    LEWIS -- fairbanks, AK   12/20/2012
    very good product, glad I bought it!
    GARY -- hillsboro, MO   12/5/2012
    Easy to install and moves plenty of air. My office is at least 10degrees cooler.
    JAMES BRYAN -- hawthorne, CA   11/21/2012
    I needed a ceiling closet exhaust fan - this was the nearest product i could find. I modified it to run in reverse to draw warm air out of the room. works great!
    ROBERT J. -- sheldon, VT   11/15/2012
    Easy to install, moves a LOT of air, medium noise considering the amount of air moved, needs an actual 8" cylindrical opening.
    DAVID -- pacific grove, CA   3/31/2012
    Works great.
    KENNETH -- newton, NH   3/8/2012
    Works awesome, balanced the room temp above my garage perfect
    LEO -- ridgway, CO   3/5/2012
    Fan took about one hour to install thru the wall. Runs quiet on low speed and not much louder on high speed. I use it to pull warm air from a room with wood stove in to garage area. Fan does a great job! Very happy and was delivered to my home fast and intact.
    ROBERT E. -- brighton, IL   2/28/2012
    moves a good amount of air. Just a little noisy
    DENNIS -- scarborough, ME   2/27/2012
    I did not wall mount this unit, I mounted it under a floor grate to get heat from the basement to the first floor. This fan works great and is quieter than expected.
