Fantech Radon Fan Review 2020: Four Things to Know Before You Buy

Radon is a deadly gas that can build up in your home. Odorless, invisible, silent but deadly, all of these terms can apply to it. Luckily, there are many products out there to help with your radon levels, and these include radon fans. Let’s look at one particular brand of radon fan from Fantech and see if it’s any good, or if it’s a bust.

What’s Good About The Fantech Fan?

Before we talk about the product itself, let’s first discuss what Fantech is. It’s an air ventilation company that has nearly 40 years’ experience since its founding in 1981. Therefore, you know that you can trust them to make quality products.

Let’s now look at the Fantech RN1 radon fan by discussing some facts around it. It’s used for appliances that are low suction and airflow. It’s UV resistant, and made from UL listed durable plastic. It’s also UL listed for use outdoors as well. UL is a safety company that creates safety standards, so if a product says it’s UL listed for use, you know you can rely on it.

Besides that, this fan has other features, such as a watertight electrical terminal box, a case that’s enclosed for protection, and more. It’s packing quite a few other features, so let me run through those quickly.

Automatic Reset

Thermal overload is when the unit has too much power, which can end up shutting it down. When an electrical terminal does get overloaded, it will shut down. However, some don’t reset automatically, and you have to turn them on. Luckily, this fan has an automatic reset to make your life a whole lot easier.

Radon Mitigation

We should mention that this fan is perfect for radon mitigation. That’s what it’s designed for, but this fan is built with pure mitigation in mind. It should reduce the overall radon levels of your home by quite a bit. As mentioned, radon is a deadly, but invisible, gas, so make sure to test your home before and after you buy radon mitigation products.

Can Be Mounted Anywhere

Another unique feature of a radon fan, especially the Fantech line, is that you can mount it anywhere. You can put it outside, inside, or where it’s wet. This is because these fans have a totally enclosed electrical terminal. This means that it won’t get water damage, no matter what. Make sure the products you buy say they are totally enclosed in order to get the most out of them.

Can Do/Can’t Do

Being a radon fan, it doesn’t have a vast list of commercial applications. Instead, its main feature is that it can reduce your radon levels at home. Radon is an often ignored problem in many homes, mostly because people cannot see it. Radon mitigation products help people reduce their levels, allowing them to live happier and healthier lives.

As for what the fan can’t do, it’s not a cooling fan. In fact, keep it away from your cooling air, as the fan can ruin it.

How do You Use It?

A radon fan is something that may require professional installation, as you do need a PVC pipe running in your home, a manometer to check and see if the fan is working, and you need to install the radon fan in the attic or top of your home. Here’s a basic installation guide.

  • First, you need to use a radon detector to look at your radon levels. If you don’t know where your radon is coming from, you can’t install the fan. A long-term detector is good for this, but it’s not within everyone’s budget. A short-term can work when you are in a pinch. Just remember that you should always monitor the radon levels of your house.
  • Also, you need to figure out the age of your home. Any home that was around before the 1970s may have a fill that is not porous, meaning that it’s harder for you to suck the air out of the ground. Also, if certain parts of your house were built on later on, you may need multiple systems.
  • Speaking of home, you need to look at the structure of your house. Depending on your drainage system, you may need to drill a hole.
  • Look at the soil underneath your house. Ask the builder of your house what soil was used, or drill yourself. Gravelly soil can help with this, while wet earth may require a little more work.
  • The actual home inspections should be done by a professional, as it can require a lot of work on your end.
  • Get a 3-4 inch PVC pipe, and drill holes in your house to put the pipe into. Don’t put the pipe in areas of the house you live in. Instead, use your garage, basement, or other low traffic areas. The pipe needs to go out of the roof but keep it 10 feet or more away from windows to avoid gas.
  • The fan itself should be installed in an area with little traffic.
  • When drilling holes in your home, find the ideal place. One example of a good location is close to a wall. This can require many different tools, like a jackhammer or hacksaw.
  • Eventually, you can lay the pipe and seal up the holes using cement. Again, use a professional.
  • When it’s all laid out, you can test everything. Use some smoke (try burning some paper,) and put it in a small hole in its foundation. You should see the smoke get sucked out. Finally, top things off with a manometer, which can tell you if everything is working properly.

Phew, what an answer. There’s a lot more to it as well. Not everyone is skilled in home improvement, or they may be worried about improper installation. We recommend you talk to a professional about install Fantech fans or any kind of radon fan for that matter. You’re better safe than sorry in this regard.

What do the Reviews Say?

Reviews of this radon fan kit have been quite positive. Most people say that this fan is easy to install and it runs well, helping people reduce the amount of radon that is in their homes. It has a near-perfect score on Amazon. However, there are a couple of criticisms.

For people who were installing on their own, the electrical wiring part of the installation was vague for many people. Another criticism is that the fan is a little loud. However, some people also said that Fantech fans are quiet. A fan’s noise can be a little subjective, after all. Overall, the reviews are good, so we recommend this fan for anyone.

How does it Compare?

Wanting to buy this product? Let’s compare it to similar products.

Fantech radon fan Vs. RadonAway

A name like RadonAway makes some big promises, doesn’t it? Anyway, for a 4 inch fan, the RadonAway costs a little more than the Fantech. The price is not that much more, but it’s worth noting. Both fans are thermally sealed, good for residential or commercial applications, and are made from heat resistant, UL listed durable plastic.

One slight difference seems to be that the RadonAway is quieter. For some, that makes it better. Others may not care, may not notice, or they like a fan sound. Both products have positive reviews, too.

Vs Tjernlund

The Tjernlun product line tends to be much less expensive when compared to Fantech, with prices for a four-inch fan going around $30-$40 fewer. Despite being a budget product, this fan works well and has positive reviews. One disadvantage is that it may be a little bit louder than the Fan Tech, but this is a little subjective, as we keep saying. The warranty for Tjernlund is also much shorter. It’s only a year vs five years for the competition. However, this may be due to the price.

Vs Suncourt

The Suncourt lineup of fans are slightly more expensive, and they still offer quality protection against radon buildup. The Suncourt fans can vary in noise level as well. When it comes to a radon reduction product, the noise level is usually the only difference.

Do radon fans have to run continuously?

Yes, a fan has to run continuously in order to keep the radon out. Sometimes, the radon amount in your home could return back to normal shortly after turning it off. Make sure that your fan is running, and if you have any problems, contact a professional or call up the company as soon as possible.

What is the Quietest Radon Fan?

Many people want a radon fan that isn’t heard. While sound levels can be a little bit subjective, as some people are sensitive to different types of noises, the quietest fan does appear to be the RadonAway brand. If you’re able to listen to all the fans in action, you can decide for yourself.

What is the Best Radon Mitigation Fan?

If you’re looking for a fan to reduce radon, the RadonAway and Fantech lineup work wonders. Both are highly rated on Amazon and other review sites, so we recommend those two.

How Do You Size a Radon Fan?

The size of the radon fan you need can depend on how big your home is. This is one of those questions where we recommend you talk to a professional. You don’t want to mess this up on your own, as buying a fan, only to find out it’s too big or small can be extremely frustrating! Make sure you get the right size, and you should be good to go.


Overall, this is a good product to have if you want to get rid of the radon in your home. While some other fans, such as RadonAway, are a little more powerful, this one is good if you’re in the mid-range budget and you need something for radon mitigation.

Radon is no joke. About 21K people every year die from lung cancer that was caused by radon exposure. These people didn’t smoke, either. You always want to do tests regularly for this gas and make sure it’s not invading your home. Get some good mitigation systems today and stay safe. Sometimes, your home may not be the safest place if you aren’t taking care of it enough.
