Love your videos, you are the GOAT radon channel on CZcams
Haha, I appreciate that!
Fantastic example/video info.
Thank you!
Just got a system installed with a 170W fan (304 CFM at 0" WC or 22 CFM at 4.75" W.C.). Didn't know enough about these systems going into this to question why I got such a beefy fan. But it's audible from both the front and back yards and certainly the deck. Quiet enough from the nearest bedroom as long as the closet door is closed, but I'm sort of hoping I can slap a muffler onto the end of the pipe on the roof.

I can't believe my radon guy didn't mention suppressors when I complained about the noise from my system. I need this!
It might be a good option if you have a loud exhaust noise.
It looks like you don't sell these on your website. Would you be able to provide any details on what foam you use in them? I'm outside your service area and would like to build one for myself. The ones I see sold online use smaller diameter pipe
They have fiberglass insulation inside.

Hey, I have a noise suppressor that I'm going to place above my fan with a 4" pipe above the suppressor that will shoot through the roof. Both the suppressor and pipe are only about 2' long. I was wondering if I need to worry about the foam inside the suppressor being affected by the elements at all.
That's a good question. I think the UV rays from the sun would do the most damage to the foam. However, you will likely have a foot or two of piping above the suppressor that will help protect the foam from the sun.
Are there fans that can be speed-controlled? Im thinking of a scenario where full flow may not be required to do adequate mitigation. Why not save on power and noise? Or is it true that more airflow always means lower radon? I wonder if there is no further radon reduction after a certain airflow is reached.
Yes, there are speed-controlled EC radon fans. You can check out the Fantech Rn2 EC and the Rn4 EC fans in our Amazon Store in the radon fans section. Amazon.com/shop/Americanradonmitigation
Bigger is not better when it comes to radon fans. There's more to it than moving more CFM. Check out this short video for a quick explanation: czcams.com/users/shortso8eOSu_ILdI?si=-SR7Dz8gow7wDJvS

What about a video that demonstrates how the size of the pipe impacts the noise? As well as the number of turns/bends present creating turbulence? I'd like to run my radon mitigation up an interior wall and place the fan in the attic, but I'm concerned about how much noise it might make. I'm also trying to decide if I should use a 3" pipe up the interior wall, or 2x 2" pipes. A 3" pipe would be tough to work with in my scenario.
That's a great idea!
I would not use a 3-inch pipe in a 2x4 wall as it will touch the drywall, and you may get a bass drum sound.
How many CFMs do you need to move to hit your target sub-slab pressure? Knowing that is one of the factors that goes into selecting the proper size piping.
Does this suppressor lessen the noise in the adjacent room where the pipe runs on the outside? The low hum is very irritating.
It's hard to say, as it could be vibration from the fan transferring through your home's building materials. You could try loosening the pipe securement closest to the fan or switching to LDVI rubber couplers. radonpds.com/product-category/all-accessories/flexible-couplers/
We close on the purchase of our home in 7 days. They (SWAT RADON MITIGATION CO.) Just installed the system in the large basement. It is ran on the outside up past the top story roof (3rd level) by approximately 3 feet. It is well away from windows & openings. The fan unit they installed is a "RADONAWAY GX4" and is placed about 4 feet up from the ground. Looks to be a very good install, being that there was no way to run it internally, thru that many floors. It does however seem to be very powerful and with that ability, a bit noisy albeit on the outside. I'm in Pennsylvania so I will be insulating the exterior. Two questions:
1) Do you think they have it turned up (higher speed than normal) do to an attempt to bring the Pic level down from 67 quicker? And then adjust the flow upon safe level achievements?
2) once I insulate the exterior run, wouldn't that in fact quiet the noise level?
On a side note... do you have an opinion on whether this particular fan is of good quality and capable of having additional extraction/evacuation pipes ran to it from other areas in the large basement (900+ sqft)? I've seen several other fans and none of them were this large. I'm wondering what the electric bill will be for this also.
1) I don't use RadonAway fans, but I don't think the fan speed is adjustable on that model. A more powerful fan does not bring down radon levels more quickly than a weaker fan as long as you have full pressure field extension under the house. It is hard to say as we don't have any pressure field data. You may want to ask SWAT Radon for this information.
2) Yes, adding insulation to the piping may help reduce the noise of the fan and the air moving through the piping. However, a noise suppressor will help reduce the exhaust noise you may hear at the top of the piping.
Side note. I don't currently use RadonAway radon fans, but I assume they are high quality. If you engineer it correctly, you can have several suction points that lead back to one radon fan. You can find the estimated fan wattage using the spec sheet. www.radonaway.com/pdfs/radon-newsletters/pdfs/GX_Series_111920_revA.pdf
@@AmericanRadonMitigation thank you very much for your professionalism and information. In my opinion (as a retired Government Supervisor, who's been certified as HAZMAT OPERATIONAL & RESPONSE for well over 30 years) you are no doubt a leader, if not the #1 leader in your field. Well done.
Thank you for the compliment! I've been fortunate to have many amazing people share their knowledge with me.
How do I get one of these
Check the description for a link.
quick question for you guys... was watching the video and considering putting a noise suppressor however the main issue that I am running into is that the existing radon fan (XR261) is causing some vibrations in the gutter pipe (thus causing the vibration to the house siding that can be felt inside).
The fan doesn't appear to be vibrating, however goes from a 6" to 4" PVC pipe (could 45) into a 3x4 reducer to a galvanized gutter pipe.
The vibration seems to be right around the 4 to 3x4 reducer causing the gutter that runs up to the roof to vibrate.
Not sure if putting a noise suppressor would do anything... been wondering if the 3x4 should just be replaced by a 4" PVC instead to relieve some of the back pressure.
Manometer reading sits right around 1.
I'm not sure what to tell you, Sam. We don't use downspout, so I've never experienced what you are describing. I'd start by trying to isolate the system from the house to avoid some noise/ vibration transfer. I don't think a noise suppressor would help with what you are describing. It will certainly help with minimizing the discharge noise, though.
