Answer: 
No, but you can incorporate a light on a switch or you can visually see if fan is running on the vacuum gauge that comes with the fan kit.

Home has 5.8 in the basement. Does the fan have variable speeds so that I may adjust it so that I don't waste power on the fan and lose heat/cooling?

Answer: 
Hello,
When installed as a sub-slab depressurization fan there should be little to no loss of heated or cooled air. The suction side of the fan is sealed under the slab of the home and is not open to the homes conditioned air. We do not recommend a variable speed switch on radon fans for one main reason. If you lower the RPM's, and consequently the suction, to much the fan can not do its job. Lower Read More
Hello,
When installed as a sub-slab depressurization fan there should be little to no loss of heated or cooled air. The suction side of the fan is sealed under the slab of the home and is not open to the homes conditioned air. We do not recommend a variable speed switch on radon fans for one main reason. If you lower the RPM's, and consequently the suction, to much the fan can not do its job. Lower RPM's mean lower suction. At some point the suction effect of the house would pull the radon into the home as if you did not have a radon fan. You also do not change the wattage used appreciably with a fan speed controller. Running watts of the Radon Mitigation fan are 77 watts. If you have any questions about this please contact us at 800-999-3267 M-F 8-4:30 central time. We would be happy to answer your questions.
Thanks,

Answer: 
Hello,
Radon mitigation fans should not be mounted in a basement or in a horizontal position. Radon mitigation fans should be outside or above all living spaces. Radon Mitigation fans should only be mounted vertically. The vertical mounting allows moisture that condensates in the pipe to flow through the fan. If the fan is mounted horizontally a pool of moisture can form in the low part of the fan and Read More
Hello,
Radon mitigation fans should not be mounted in a basement or in a horizontal position. Radon mitigation fans should be outside or above all living spaces. Radon Mitigation fans should only be mounted vertically. The vertical mounting allows moisture that condensates in the pipe to flow through the fan. If the fan is mounted horizontally a pool of moisture can form in the low part of the fan and impact the fan blade.

Answer: 
Sure 4" to 3" will work find. It is really a matter of preference. You might consider doing one penetration and then testing before you do a second penetration. You might not need it.

Customer Reviews

Rated 4.3 out of 5 by 49 reviewers.
Rated 5.0 out of 5.0 by Suncourt Radon mitigation fan Good product, easy to install. You will need a cord, I cut one off of an old halogen shop light (2 prong with a ground). Unit only pulls about a 1/2 amp so it does not have to be a very heavy wire. October 4, 2016
Rated 5.0 out of 5.0 by Good buy When my house was built 25 years ago, contractor installed 3" ABS piping to roof, including sub-slab perf pipe for future radon mitigation. My radon levels measured over twice the recommended 4 pC/L, so I finally got around to mitigation as a DIY project. I had problem in attic, because the existing pipe was almost all at 45 degrees, with not enough vertical for the fan. I had to modify attic pipes and elbows to get a 22.5 degree angle, allowing a good vertical run for the fan, after which the installation was pretty straightforward. I haven't yet measured my post-mitigation radon level - expect to do that in a week or so. Just a little bit of noise heard in room below. April 19, 2016
Rated 5.0 out of 5.0 by DIY radon mitigation fan The installation from beginning to final needs to be researched before starting. Lots of videos on line can help. This Old House has an excellent video on installing Radon Mitigation. September 20, 2016
Rated 5.0 out of 5.0 by Good product, good price Installed with bypass as required in northern climate. Radon went from 7pC/l to 0.7pC/l three days after installation. I had to add elbows in condensate bypass to use included wall brackets. It was the only one I found for sale with the pressure indicator included. That helped me choose Suncourt over others. January 26, 2016
Rated 4.0 out of 5.0 by Good solution to the problem Some of the negative reviews that I had read were due to excessive noise. I installed the fan per the instructions and it is rather quiet. It came with a pressure indicator so you can see that it is pulling a vacuum. February 25, 2015
Rated 4.0 out of 5.0 by so far so good easy to follow instructions and worth the safety and value May 3, 2016
Rated 4.0 out of 5.0 by the fan is quiet but need some work on electrical power connection The fan runs very quiet and smoothly. Everything is fine except the electrical power connection. Need a power cord with the plug to connect the power. April 27, 2016
Rated 5.0 out of 5.0 by Nice fresh air fan My goal was to get some fresh air moving in the basement. If this fan could accomplish that goal, I had planned to buy a second fan, to add a full radon removal setup to the sump hole where we have radon. (Radon is only emitted from one of our four sump holes). However, after adding this fan in another area (well away from the radon source), the radon detectors (at the source) now indicate normal radon gas levels. I've checked it twice and our radon problem seems to be gone. Just by adding a little fresh air flow. Currently running the fan 7 hours a day, and the average reading this morning is 1.6 pCi/L (third test). Tested with both detectors hanging 16" above the 'open' sump hole. The 'Before' (fresh air fan) reading was 4.6 pCi/L with the sump hole sealed. (Before flooding necessitated installing the sump pump). June 25, 2013
