Fantech RN2 Radon Fan | 4 Inch | Quiet and Efficient Radon Mitigation | 220 Cfm White

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.

The fan is in our attic. We were able to reduce the radon in our basement from 4 to less than .5 and we can not hear the fan when in the room below it. Couldn't be more pleased with its performance.

I tested for radon when I first moved in and it was low. Unfortunately that was in summer when levels were low. I'm in Oregon where radon's lower than other areas so I didn't pay it much mind. I got an airtthings radon detector on a whim at Home Depot and as soon as it started raining in fall levels crept up and when it went past 4.0 I knew I had to do something. I almost called a company but saw that estimates would be around $1500-$2500 to hire it out. I looked at the materials and saw the job would run me about $250 to diy. I took a couple weekends to do everything but the whole job ended up around $140. I have a floating floor through most of the finished daylight basement but it was manageable to pull up the carpeted areas to seal cracks and found a good spot for the suction pit in the central hvac room. Radon levels weekly averages are 1-1.3pCi/l and overall averages are down to 1.1pCi/l. I'm satisfied. Looks like I got the RN2 at a good price compared to now but the fan is great quality, has strong suction and easily installed as a homeowner. I can't recommend this enough.

We got this fan last week. Installation was generally easy - however two issues1) This fan was a couple of inches shorter than the Fantech HP190 that was installed and came with the house - that old fan had started making a high-pitched sound. The shorter length was a non-issue as the piping was adequate.2) The new RN2 fan required a couple of 4.5" OD to 3" OD reducers (and the previous HP190 had 4" to 3" OD reducers in place). We had to go get new reducers from Lowe's

I replace an old Fantech radon fan with this new one. It was simple to change out and it runs very quietly.

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.

Perfect for the job. Quiet, efficient!

First failed in 4.5 years, second failed in 8 months.My first fan started make a very loud noice.I purchased a replacement from Amazon and installed it in May 24. As of December 24 I noticed our Radon levels were rising, and the manometer was level (system is not functioning). Checking in the attic the fan is only operating intermittently, so suction isn't maintained.I reached out Fantech and they say you need to work with your "distributor" for a warranty replacement. Amazon says they can't do anything outside of 30 days and to go back to the manufacturer.I'd recommend a different fan, and I'd recommend not purchasing it on Amazon since they apparently don't recognize the manufactures' warranties in this category.
