#1 Q:   Currently have a Fantech FR150 duct fan which was part of the original radon removal system installed 25 years ago. The fan is located outside and needs to be replaced, however I have read that the FR150 is not supposed to be used for radon removal applications. I am confused, what fan would you recommend as a replacement for my current FR150?
A:   You can still use the FR 150 if you want a direct replacement. The new Rn fans are better sealed than the multi purpose FR series and can potentially last longer outside. Having said that, getting 25 years out of your FR 150 is great.

#2 Q:   I need to replace my existing Fantech Model HP1290 Radon Mitigation Fan (Installed in 2006). Apparently the model has been discontinued. What is the recommended replacement for the HP1290?
A:   The Rn2 would be closest replacement in the new line up.

#3 Q:   I have a new 700 sf home with basement, at least 4 of gravel below the slab. House was back filled with gravel 3 sides to relieve soil pressure. . Current radon level is 4.2 after sealing slab at perimeter and applying 2 coats of radon seal (was 18). Pipe run will be 30 horizontal and 25 vertical, about 9 elbows. Can you recommend a fan. I would prefer to use the RN2SL if that would work.
A:   Rn2SL is a safe choice. It has similar performance to the workhorse Rn2 model but with better aesthetic. One step up would be the Rn3 but you have gravel under the slab so radon communication is not an issue.

#4 Q:   I am replacing an old AMG SPIRIT fan (about 12 yr old). It is a low power fan with a 3 and 3/8 flange. about 9 tall and 12wide. It is installed in my garage and connected to 3 pipe by what appear to be 4 couplings. What can you recommend. Form fit replacement is top priority and energy efficiency is second
A:   Fantech lists the Rn1 as the closest replacement for the AMG Spirit. The dimensions are slightly different from your old fan. You can see all the dimensions under the Specs tab or in the PDF spec sheet:
