Fantech Rn3 Radon Fan 6" Duct - 285 cfm

I bought this fan because I did a home radon test. My levels were 36. Looking at "professional" installation, costs varied from 2 to 3 thousand dollars. I watched several YouTube videos and decided on a self install. I Had a sump in my basement and made a plexiglass lid, I used 4" schedule 40 PVC pipe running up through the attic and out the roof. This way there is no ugly pipe running up the side of my house. I used 4" to 4" rubber coupling I bought at the hardware store to connect the fan to the PVC. I read a bunch of reviews complaining about the warranty not valid unless its installed by a licensed installer. DO THE MATH. I paid $120 for the fan and approximately $100 for pipe and fittings. I can replace that fan numerous times before I get to the cost of professional install. DIY .My levels are 0.29 after MY fan install.YouTube it and do it....

I had an old Fantech HP190 radon fan in my attic that was getting very loud. I replaced it with the new Rn2 model and am quite happy. The Rn2 seems well built. The Rn2 is slightly shorter and has different size connectors than the HP 190, but I had no problem finding some flexible PVC couplings that worked perfectly at the local hardware store (I used a 4" x 4" on bottom and 4" x 3" on top). The bigger problem was that whoever originally installed the fan used 3" PVC pipe with 4" adapters cemented in the ends. That gave the fan a little more stability, but made it impossible to slide the coupler up the pipe to remove/replace the fan. I ended up having to cut off the top 4" PVC adapter along with some 3" pipe back far enough that would allow me to add a standard 3" PVC coupler and 3" PVC pipe to get it to the right height so that the fan could easily slip in, but still allow the coupler to slide up the pipe for installation/removal. Wiring up the new fan was no problem, I just used the plug from the old fan. The new fan is working great and quiet. Fantech included a tootsie pop and an "Our fans suck" stick in the box for fun.

This Fantech radon fan is very cheaply made. Much more noisy that other Fantech fans I've installed and used in the past. There is no place in the fan electrical box for attachment of the ground wire of the cord or cable that you must add to the product ... .I made my own attachment to the metal romex clamp holding the cord in place. There were not even any screws provided for the cover of the electrical junction box .... I had to find my own self-tapping screws that would fit. Worst of all, no mounting bracket was supplied with the fan and I had to make my own out of wood and metal shelf brackets. Surprised at these corners being cut.

Bought this mainly because the Radon-Away only has a 1 year warranty if you install it yourself. Fantech has a 5-yr, which goes to 6 years if you register. Installed it in my sump pit and Radon levels dropped from 40 to 0.5. So I added a "Cdmall Electronic Fan Speed Controller Variable Adjuster for Hydroponics Inline Duct Exhaust Ceiling Fans with 6' Long 120V 15A Cord" which let me reduce the fan speed so it runs quieter and uses less power. It wasn't that loud to start with but now you can barely hear it, and the Radon level is about 0.8.I installed it inside the basement thinking it would hold up better not being exposed to temperature extremes. I know the EPA wants you to put it outside but I did this to reduce Radon, not to please the EPA. Plus I have confidence in my mad skills at gluing PVC pipe together. Left room outside so I can move the pump outside if I sell the place. Bought the install kit which made the it very easy to hook up. Hardest part was cutting a hole through the basement wall.I also want to mention that the screws for attaching the lid over the electrical connection compartment were in a plastic bag kind of wedged in the bottom of the compartment; not that easy to see. Another reviewer said they were missing. Also, this does not need to be grounded and there is no place to connect a ground wire. I just used a 2-conductor cord I'd salvaged from some other appliance - finally my hoarding tendency has been vindicated.

I purchased a real-time radon meter for my basement to see how the radon levels in my house was. Of course, it came back higher than I was comfortable with 😒. I looked online and saw that the sub-slab ventilation was fairly straight forward. I drilled a hole in my foundation and used this fan to de-pressurize under the slab. The fan moves a good amount of air without much noise. I was able to drop the radon levels in my basement to below 1 pci/L. The fan wired up easily and came with one of those Chupa chup lollipops. Only time will tell if the fan will last. I would definitely recommend this fan for the do-it-yourselfer.

I bought this unit to replace my old radon pump/fan.First off, I am not a licensed radon technician. I thought I had 4 inch pipes but I did in fact NOT have 4 inch pipes. Secondly, I find myself to be a little bit of an overdoer. So I bought some rubber unions and reducers and made the thing fit.I wired it up, turned the breaker on, and it took off running. Initially, I didn't know what to think. It was quite a bit smaller than the old pump so the performance might have suffered a little, but it holds steady at 2 on the vacuum. Its pretty quiet even right next to it. I do notice a little bit of resonating sound upstairs by where the pipe is outside, but its also pretty quiet.

The above photo is taken 20days after the fan wad installed.I have 1100 sfm footprint concrete slab in the basement. This DIY job is to improve the indoor air quality, hopefully to reduce the radon level from 150-200 Bq/m³ to somewhere minimum level. The piping (3" PVC S40) starts from furance room and runs into garage up at attic to the roof. The work runs smoothly and has taken 4 days to complete including material preparation. Upon running the fan, the current level (measured at 2nd floor) has droped down 70% at 12th hour, and 90% at 24th hour almost nothing left. Therefore, the objective of this job is achieved. Among many radon fan products, Fantech Rn2 is selected based the size of the footprint, noise level, sucking capacity and warranty length provided. Looking at the redult, a right fan is chosen. The fan is nicely manufactured and looks like fine quality. The amazing one is the noise level, extremly quiet!

I only used it one day. This fan makes very high-pitched. It bother my neighbor and my family. If you want to get more powerful than RadonAway RP145, maybe you should choose RadonAway RP265. The Fantech rn3 is not good for you.

This fan works! Brought the radon level to almost 0 in no time. Very happy with the results and easy to install.

Great fan, moves a lot of air.
