## Description

Suncourt 4-Inch Centrax Inline Centrifugal Fan — Quiet Duct Fan for Exhaust, Ventilation, or Inline Boosting, Safety Certified, Simple Installation, 10-Foot Power Cord (TF104-CRD) - desertcart.com

Review: Super quiet! - I ought this to replace an identical fan that started making noise after 9 years of continuous use. It installed easily, and is barely louder than a whisper. It vents our crawl space and does a great job Highly recommend this Centrax fan.
Review: Working as expected. - TF104-CRD is supposed to be the version with a cord however what was received (twice) was the version without the cord. Not a big deal but they should post the correct model # TF104 (This was when this listing was from National Trade Supply, LLC). Good value. Performs as expected so far. Purchased another unit for another bath fan. I hope these will last beyond their 5 year warranty. But since they have only been making them for ~5 years (2012) no way of telling. Seems to be of similar construction as similar in-line fans but no way to tell how well the bearings will last. However as a bath fan (intermittent) vs radon (continuous) fan I hope they will last a long time. Mounting bracket is included. No cable grip included. Comes with 3 position screw terminal for attaching power. Update: After 4 years the fan are still operating as expected. However I did notice that this review and the link from my previous purchases goes to this new listing. I find it interesting that desertcart will move the reviews from one vendor to another. Not very quite if the duct length to the fan is short 10' - I Original installed this fan in-line at the end of a 40+' run (crazy I don't know what the home builder was thinking) and it was fairly quite but after moving it to a new roof vent closer to the bathroom it is as loud as a Broan 690 upgrade. I may try to put a speed control on it to slow it down as this bathroom is small and does not need the full airflow of the fan.

### ⭐⭐⭐⭐⭐ Radon levels dropped instantly!
*by E***N on September 20, 2023*

Easy to install! The instructions were good, even showing the PVC fittings that were needed to construct the mitigation system, all of which were available at my local home improvement store. We have seen the levels of radon go down significantly since we installed this. We would highly recommend this product! Well worth the money spent to keep our family safe!
