Tech Drive Bathroom fan 110 CFM, 1.5Sone No Attic access Needed Installation,Very Quiet Bath Ventilation and Exhaust Fan, Ceiling Mounted Fan,White Plastic Grille

Perfect item. Excellent flow and very quiet. Will be buying for our other bathrooms.

If your fan is old and loud and driving you nuts, this is the way to go. It's whisper quiet and does a great job drawing out the steam.

My house is around 20 years old, and the original Braun fans were getting old and noisy. Since I have existing construction and the four fans in my house are near impossible to get at due to their placement under decade's old insulation, I decided to purchase some replacement fans that could be replaced without having to get in the attic. The Tech Drive bathroom fan, at first glance, checked my boxes: I needed something easily installed, and I wanted something quieter than the jet engines that were the Brauns. They were about 20 dollars more expensive than the Brauns, but if they were quiet and easily installed, it would be worth it. I bought 4. The first two were installed without issue. The hardest part was having to partially disassemble the Tech Drive fans so they could be installed without having to get into the attic or crawl space. But I got them installed, turned them on, and glorious quiet! These fans are significantly quieter than the Braun fans I had before. Probably 1/3rd of the noise of the Brauns. My kids noticed immediately, they thought the new fan wasn't working because they couldn't hear it. With the Brauns, I could pretty much hear them running just about anywhere in the house. With the Tech Drive fans, I had to be right next to the door of the bathroom they were installed in. Super pleased. Went to install the third fan, and unfortunately, I was met with an issue. The little door that sits inside the plastic exhaust had broken off the pivot. I didn't notice until I got the fan installed and turned it on. It was really loud and I could feel air blowing back into the room from it. That's when I disassembled everything again and discovered the broken door. Bummer... Had to take the whole assembly down, box it back up, and return it. Fortunately I had the fourth fan, so I put it in instead and it worked fine. But now I'm short a fan. Amazon is awesome as usual and is sending me a replacement without a problem. Bottom line is, these fans are really nice. They are quiet and easy to install. My only issue was the broken exhaust door, and the reason why I left four stars instead of five.

This fan really saved me so I wanted to write a review to share my experience. I previously had a 70CFM 6.0 sone fan with a 3" exhaust in the bathroom that would never properly vent the steam from the bathroom. It was also installed so far down in the corner that it was not accessible from the attic. The 1st problem was to get the old fan out with out going in the attic. I used a crowbar to stretch the metal where it was screwed to the wood. Then the old fan came out easy. I had to enlarge the hole since this fan is bigger. Then it easily mounts with 3 screws. The only problem left was reducing the 4" duct to fit my 3". I know it is best to change whole vent hose to 4" but again that was not an option since it is in such a small area in the attic. Some people have had trouble finding an adapter to fit but I found one...https://www.amazon.com/gp/product/B08JVG4J85/ref=ppx_yo_dt_b_asin_title_o04_s00?ie=UTF8&th=1 It fit right in the fan duct and still allows the damper to operate...then I could use foil tape to secure it. Perfect Install!!!! It is not completely silent but it is way quieter then my old 6 sone fan. It provides just enough background ambient fan noise. This is a life saver for anybody that cant get in the attic but wants to upgrade their ventilation.

Works as expected. Not loud at all.

Replaced the original builder grade fan just because I hated how loud it was. The fan ways 7 lbs, so plan ahead and have a helper. It will require more support than the old one you remove. For a very experienced do it yourselfer or a pro, it will take about 2 hours. I needed attic access to install the bracket between my 24” on center trusses, to move the blown in insulation , to replace the flex duct and because the duct connector wouldn’t snap back in to the top of the housing when installed from below. You very likely have 3” flex and this requires a 4” vent. I went up and moved the insulation out of the way. I disconnected and removed the old fan. Made the hole bigger, removed the duct connecter (2 screws) and hooked up the duct and the wiring from below. I pushed the duct connecter through the hole, then the fan. Screwed the fan housing to the joist, reattached the duct connecter then went up in the attic to install the bracket and rearrange the insulation. This fan is very quiet. I’d recommend it.

The interesting part about this fan is that it can be taken apart and the insides of the fan fit relatively snugly into the metal box housing of a Broan 688 - NuTone vent fan, which is the standard mass-market and cheapest vent fan installed by builders throughout the US. The Broan 688 is substantially noisier and at least 60% cheaper which is why it is installed everywhere. This fan costs a lot more but it has roughly 1/3 of the noise level of the Broan 688. So on new constuction you can install whatever you want, but if your house is already equipped with Broan 688s, it may be sensible to retrofit some of them with this fan's parts, and you don't have to tear up sheetrock to do it but can use the existing metal housing. The fan is relatively quiet but not the quietest out there. It runs on 12V which makes it very slow to start. It takes 3-4 seconds to begin spinning at a working speed. The construction seems good quality and it is packaged with good care. Seems like a decent quality product.

We were getting mold on the ceiling and trim from the original fan that was placed. We replaced with this fan and the ventilation is so much better and stronger we have not had any problems with the moisture or mold since! Easy to install
