Suncourt ThruWall Room-to-Room Transfer Fan — Quiet Through Wall Vent Fan Improves Air Circulation Between Rooms 100-275 Sq. Ft. | 10’ Power Cord, 2-Speed (TW408)

Works great! Easy install in typical interior drywall structure. Very quiet and moves air from equipment closet well. I modified to reverse the flow, so it blows away from the cord. How i did it: pop off the grill cover with the switch (use narrow flatblade to disengage 3 clips), remove fan blade (it pops off, pull at the hub so you don't break blades), remove two bolts holding motor to bracket, slide out armature (drive shaft), rotate motor frame 180⁰, reinsert armature (long shaft away from grill side, to accept fan), snap on fan blade, snap on grill cover (adjust wires as required to avoid contact with moving parts, ziptie if needed). Do at your own risk (I work with mains power often, but no wiring is needed here)!!! Also, light machine oil on bushings. No clue how/if this will affect longevity.

My office closet is converted to a "server closet", with a few servers and various pieces of network equipment. They generate too much heat to allow passive cooling from underneath the door, but not enough heat to have a dedicated A/C vent or standalone A/C unit. This fan helps pull air through the office, under the door, and up to the top of the wall where it dumps the excess heat into the HVAC room. Even on Low, it pulls more than enough air to keep the closet temps consistent, and pulls some extra air into the office. Helpful when I'm pushing my desktop hard while gaming. The fan was easy to install, and I appreciated the convenience of a standard plug instead of monkeying around with electrical wiring. I would have liked the option, maybe on a different model, to have an inline-switch somewhere near the plug end. Instead of on the unit itself. -But I don't adjust the fan speed often enough (hardly ever, actually) for it to be an inconvenience. The fan is rather quiet, and the only semi-annoying sound I get is a bit of humming resonance in the adjacent hallway. But that's because of the architecture of the house, not because of fan vibration or imbalance, and I don't sit in the hallway so it's a non-issue.

The fan is great, Works great and looks good. You can hear the noise at high speed setting, but not much an issue for us, since we only us it to blow cool ac air into other room at the day, during night we use the low setting. At low speed the noise is still there, but not too loud that you can't sleep. The construction is all metal. so it should last long. Installation is simple, just cut a 8" hole into the wall and screw it in. Just make sure not to cut in between any stud or wiring.

Purchased this fan to get warm air from a hallway/main living area into a bedroom on the northeast side of our house. That room has two exterior walls and is always cold in the winter. Our house is heated with hot water baseboards, and this room seems to be on the end of the loop in addition to being on the coldest side of the house. Because framing around the door prohibited me from installing this fan over the door (and there wasn't any other wall available to go directly through), I had to install 8" rigid ducting that went from the hallway, through a cabinet in the adjacent bathroom, and into the bedroom. There's about 36" of ducting total. All connections were made using sheet metal screws and foil backed tape to ensure no warm air leaks into walls - which could lead to condensation and mold/mildew. According to the size/performance chart in the instructions, this fan is for is almost too big for the room (about 100sf). So I use the fan on low and left one small cap and one large cap on, as the directions indicated. I think having additional ducting actually works to my advantage, since the fan's ability to move air is somewhat diminished by having to 'pull' air through that duct. I don't have a traditional install to compare this to, but I will say that the fan is working fantastically for my bedroom. Warm air enters the top of the room and pushes the cold air back into the living area through the gap between the bottom of the door and the floor. The fan is plugged into a Lux Win100 thermostat so it turns on only when the thermostat calls for heat. The fan noise is very low, in my opinion. Just gentle white noise. Dings - - Installation instructions. The instructions make it seem like utmost precision is required when cutting holes, but that's not really the case. I wouldn't advise anyone to be purposefully sloppy, but a little a little slop is ok. - More importantly, I was not impressed by the way the inlet cover is supposed to mate to the flanged sheet metal sleeve. It looked like the flange was supposed to mate with the plastic housing, but the sizes don't match. So you're left just kind of 'making it work'. That's not the end of the world, but some kind of snap fit would work much better. I almost took a star off for that, but it's not a performance issue. All in all, this is a fantastic solution since it works great and it's way cheaper than buying and running a space heater.

Installed and in 1minute the blade come off bad product

Does exactly what it says. Great price. Just ordered a second one, just incase it breaks at sometime. We have a bedroom that doesn’t get enough air conditioning because there is no ventilation to let air out so only some much air can flow in. This is the perfect solution.

Nice and quiet and easy to install...running great so far (2 weeks ish).

Works well

Installed it between the living room and bedroom to distribute the cooler air. Works great. Very quite.

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.

this fan is quiet enough for our family room and moves air heated by our heat pump into the room. happy and buying another for a new addition going up. (we use it mostly on the lower setter (which is more than adequate for our small rooms)...high setting sound is more invasive.
