Fantech HP 2190Q 4" Radon Fan | HP2190 Efficient Quiet Mitigation

This is a great fan, and was easy to install.Pros:*Easy to wire up, and has a wiring diagram with the instructions and a reminder wiring diagram adhered under the water resistant housing.*Used a 4"x4" rubber coupling with hose clamps to install in my Radon mitigation system (for easy replacement, if needed).*Plenty of suction, and seems well-balanced for very little operational noise.*Able to be wired with a fan switch in series to turn down the cfm.*The hard plastic body and metal impeller seem suitable for long duration use. It felt like a precision machine when I held it and spun the blades.Cons:*Does not start up with the "low" on my fan switch. This is not a ding for full time, full flow operation, though.*Pulls so much air, the pipes were whistling even with a 4" PVC installation. Hence the need for a fan-switch to turn it down. I'm running this in my attic, so want to reduce the sound of air movement, if possible. Again, the fan does what it is advertised to do, and it's not the fan making the noise, so its not fair to penalize the fan. Perhaps any fan capable at the same CFM would produce the same result.After further thought and observation, it's probably overpowered for my Radon mitigation needs, so I am running it on medium using a Lutron 3-speed rotary fan control. If I need to turn it up again, it's as easy as the twist of a knob.

This is a great fan. It is even quieter than I thought possible and it moves plenty of air. And well built. I really wish the pictures here on Amazon were better, so how about I add some.I installed it in my home. So for my fellow DIY people out there, here's some info on the install. This is for educational use only, don't blame me if anything goes wrong for you.The idea is to use the home's sump hole and drain tile to create an air flow through the soil to lead the Radon gas away from the basement before it finds it's way in the home. That's right, you are pulling air through the soil, not venting indoor air. So in one picture you see how I covered the sump pump with clear acrylic and sealed that to the floor. I got a little fancy and added a smaller access door to it so I can service my sump pump easier. The large 3" PVC in that picture is the suction PVC that goes to my attic. In the attic you will probably need a couple rubber adapters to make the fan fit your PVC. Since my pipe was 3", these  Fernco Inc.P1056-43 4-Inch by 3-Inch Stock Coupling worked well for me. They also isolate vibrations from following the PVC. I also went the extra step to install a condensation/rain bypass hose around the fan to protect it. The details are in the pictures.I hope that helps. If you find it useful, please vote it up. Have a great day.

Purchased to replace the exact same model on my house, which failed after roughly 9 years. Installation was pretty easy as it was the same model. The only curiosity I noted was that the hole for the wire is now on the side instead of the bottom. I would think this arrangement would be more likely to allow water seepage - which would be an issue as there is no weep hole in the electrical chamber. Fan construction seems improved over 10 year old model, but still don't understand why they just don't build in some moisture protection instead of requiring a Rube Goldberg arrangement to avoid condensate. After all, they know where these are installed. OTOH, it guarantees a certain number of replacements - not that any manufacturer would think that way...... Like the previous model, doesn't create a significant amount of pressurization, so reading the manometer is tricky at best. But, it makes the house compliant and that's what really counts.

Based upon the other reviews I read, this Fantech HP2190 is pretty much what I expected. It is fairly light weight, efficiently designed and seems to function well for constant air flow. The only negative I will mention is that it lacks any clear instructions. The sheet that comes with it shows a simply schematic for hard wiring, but does not list current, voltage, wattage or any such specifications. It would also be nice if there was an airflow indicator on the fan housing. You have to guess prior to supplying current to it, and it not that big of a deal if you have it backwards, but some indicator for this would be helpful. It is relatively quiet in operation and the housing stays cool when it is running, which means the fan motor is not producing very much heat (a good thing to my mind). Only time will tell how long it will last. For now, I am quite pleased with this fan.

It is difficult to figure out what sort of fan to use as replacement unit if you're not buying the same identical one. I purchased this thinking my old fan was on its last legs. It was 10 years old little noisy and the water column indicator showed only about 1in of negative pressure(was 2.5 last year) . Radon readings were still within normal range 1.6-2.5 depending on outside temperature swings. This thing is quiet and only pulls 80 watts or so. Installation was super easy no special tools needed. This unit flows a lot of air BUT the vacuum produced was only about half of my existing vacuum under same conditions. My Radon readings jumped about 0.5-0.7 after a day of running this fan still WNL but worse. My old fan was the amg Eagle. After more research I stumbled across an article that compared the various fan types (see picture) and realized this was not a good alternative. Ended up paying a hundred bucks more and buying the original fan elsewhere (not sold on Amazon or at my local big box store) and all is well again. If you're looking at cross references for fans see my attached pics. I'm not a big gp 401/501 fan based on their hit and miss long term quality so went back to AMG.I Returned this without issue.

I recently bought this item and installed it two days ago. I connected it to the radon pipe my house builder had installed plus tied it into my sealed sump pump pit. While installing all the three inch PCV pipes (2 days) my radon readings went up over 1000 in the basement. After two full days since the installation was completed my two day average is 86 and my one day average is 16. I’m very pleased. I suggest that a fan speed controller be included in the package. I purchased one and now have it running at the low speed.

This is top notch. No complaints here! Works flawlessly and it's silent. I have to check the manometer to make sure it's running. Extremely power efficient. What more could you ask for! Thanks!!!

works as it should so far...dramatically brought down my radon levels (below 100 units), much to my surprise and delight..this was a do it yourself project in a mid 1930's house...

Exactly what I needed
