It installed easily, and is barely louder than a whisper. It vents our crawl space and does a great jobHighly recommend this Centrax fan. ### ⭐⭐⭐⭐⭐ Long lasting, zero maintenance *by on Reviewed in the United States June 6, 2026* Worked great with no issues for over 14 years. ### ⭐⭐⭐⭐⭐ Working as expected. *by on Reviewed in the United States October 3, 2012* 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 Amazon 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. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/712902288-suncourt-4-inch-centrax-inline-centrifugal-fan-certified-tf104](https://www.desertcart.hr/products/712902288-suncourt-4-inch-centrax-inline-centrifugal-fan-certified-tf104) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-08-14*
