Review: Works great! HOW TO: Reverse Flow - 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.
Review: Great Fan - 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.

## Features

- BALANCES TEMPERATURE BETWEEN ROOMS: Designed for rooms that are too hot or too cold, Suncourt ThruWall Room-to-Room Transfer Fans mount to the wall to quietly and efficiently transfer air from one room to another. Perfect for three-season rooms, dorms, hotel suites, assisted living, modular homes, utility rooms, bedrooms, offices, and more.
- EASY INSTALLATION: Install in any 3-3/4” to 6-1/2” thick frame wall using minimal tools. No hardwiring required—simply plug it in with the 10-foot power cord to maintain a comfortable environment in rooms 100-275 square feet.
- ULTRA-QUIET OPERATION: Engineered and assembled in the USA for minimal noise, this through wall fan features a 2-speed motor for customized airflow control. Use the included airflow adapter plates to fine-tune airflow at either speed. The sound level is less than a desktop computer’s dBA.
- ENERGY EFFICIENT: The wall fan distributes conditioned or heated air (from rooms with PTAC units, mini-splits, fireplaces, wood stoves, and window air conditioners) to an adjoining room. Designed with low energy consumption in mind, the room to room fan maximizes airflow while minimizing energy use.
- DURABLE & RELIABLE: Delivering trusted performance since 1988, Suncourt’s ThruWall fans are independently certified by MET Laboratories to meet UL 507 and CSA safety standards and are backed by a 1 year warranty.

### ⭐⭐⭐⭐ Great Fan
*by A***R on June 9, 2016*

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.
