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) - desertcart.com

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 product - 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.

## 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 product
*by E***. on December 20, 2025*

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.

### ⭐⭐⭐⭐ Does the job
*by B***. on August 18, 2010*

We purchased this fan about 5 months ago and its working fine. I needed to get extra ventilation into a utility room. This fan moves alot of air even on the low speed. Installation was easy enough, I completed the job in about 30 minutes. The fan is a little noisy though. This is not an issue in a utility room (about the sone noise of a mid priced bathroom exhaust fan) but if it was in a room that you want quite it may be a little bothersom. Keep in mind if you are venting into a closed room you may want to put a another vent (passive) in the room so that the air can circulate back out of the room. This fan is also larger in diameter that what it appears on line so I would recomend that you take the time to mark how much space this will use on your wall before ordering.
