RadonAway RP145c Radon Fan P/N 23030-1 Inlet/Outlet Diameter of 4.5

I replaced a Unit that was installed by a Professional Installation (ripoff) Company and they installed it through the foundation sillI have listened to the vibration on the house pipe was attached to the house also and the pipe through the foundation was resting on the bottom of the Cut hole...7 years!!all in all the pipe needs to not rest on the foundation or you will get constant vibration and noise no matter how quiet the unit is it has to NOT touch any part of the houseI installed the new motor as the last cheap one installed was vibrating and as the weather got cold or wet it got double noisy.... I kept all parts and pipes off the house and you would never know I even have one on my house now...the installers do not care if you have vibration or noise they just want your cash and off they go!! This is also much quieter than the last one and is Great No Complaints!

Fit like a glove and works perfectly!

If you are replacing an old radon fan or have a newer home, with a passive random system already (e.g., a pipe leading from the sub-slab of concrete through the attic and to the roof), along with a pre-installed electrical outlet in the attic, then this is a fairly simple project to do yourself.The RadonAway 145c is the most commonly used fan. It has moderate suction, and it is ideal for gravel and concrete slab basements. Below is a variety of information pertaining to installing the RadonAway 145c and more:Get a radon detector that measures a weekly average because radon can vary greatly throughout the day and week. I have the AirThings radon detector from Amazon. I had a second one and the readings were the same, so at least the reliability is good.Get a RadonAway manometer to test the suction of your radon fan. This will ensure the fan is working well and there are no leaks in the system. For installation, search “Installing And Understanding Radon Mitigation System Manometer” by Heathy Air Solutions on YouTube. However, ensure you drill the hole in the pipe about two inches lower than the top of the manometer. Also, when you get the manometer, it might not be even on both sides or set to 0. Don’t worry because it adjusts by sliding up and down. As for it not being even on each side, that is also normal. It will even out once you take the tube stoppers off the top of either side.As for installing the fan, here are the steps I used:1. Get all the supplies: radon fan, 2 pipe-to-fan connectors/couplings (the 145c model has a 4” connection size and my radon system pipe was 3”, so I got 2 Fernco 3”-to-4” couplings), electrical cord (HomeAire (AKA RadonAway) Power Cord Kit - 6 foot on Amazon will get the job done) [yes, it does not come with a power cord for some reason], PVC hand saw or fine-tooth sawzall, razor for reaming the inside of the pipe after cutting (optional), file for filing the edges of the PVC after cutting (optional), and flat-head screw driver or socket wrench for tightening the coupling.2. If applicable, and the pipe goes to the attic, install in the attic, not the basement.3. For installing the power cord, your fan might have two or three wires for the electrical. According to an Amazon answer by RadonAway, either way is fine, and it just depends on which manufacturing facility produced it. However, the power cord has three wires. If your fan only has two, then just cap the third one on the power cord, the green/ground wire.4. Test the fan by plugging it in prior to going up in your attic. Shake it to ensure nothing is loose or trapped inside the fan.5. Affix the coupling to the fan on both ends prior to heading into the attic.6. Take all your supplies to the attic.7. Cut the pipe. I cut out a 11.25” chunk of pipe because the total length of the fan and the couplings was 14.25”. Then, I subtracted 1.5” for each end of the coupling.8. [OPTIONAL] File the outer rim of the pipe on both sides.9. [OPTIONAL] Using a razor or reaming tool, ream the inner rim of the piper on both sides.10. Plug the fan in, then check your manometer to ensure it has proper suction. The max should be about 1.75, and mine come out to 1.25.As for the sound, it has a fairly mild humming, even through the ceiling, but you will get used to it in no time. I sleep with a sound machine, and at worst, it just adds to that noise.I hope this helps and saves you some time!

I like the quiet inside and it sounds good and not bothersome. I don't like that I can hear the noise when the air leaves the tube outside, although the installer just vented it outside below the front window and not above the roof. I replaced this with what the installer put in which was a smaller unit same company yet it was loud right in the kitchen as well as when the air goes outside. I plan on extending the outside tube to a location where it won't be heard. I am overall very pleased and would give 5 stars if i didn't hear and unpleasant noise outside. I don't think any unit would be much more if any quieter then this and it works great, it is a pleasant sound when near the unit as well. I highly recommend buying this!

Had a nearly 10 year old RadonAway fan that was getting louder and louder, could hear it throughout the house sometimes. Got this as a replacement, nice an quiet! Hope it lasts another 10 years.

I’m not an electrician, but this is pretty straightforward- black to black, white to white. It already comes grounded, so, per instructions , I just tapped off the grounding wire coming into the fan.
