Radon Fans

How to choose, replace and troubleshoot radon mitigation fans.

Radon fansRadon mitigation fans are the mechanical heart of a radon system and are sometimes referred to as “radon pumps.” The radon fan is typically the only moving part in an active radon mitigation system. Radon fans are often added to passive radon systems (radon systems without a fan) to improve performance and further lower the radon level.

Radon fans are incredible work horses, they run continuously 24 hours a day, 365 days a year for an average of about 10 years. In time radon fans wear out and need to be replaced to keep the radon mitigation system functional. With dozens of different radon fans to choose from it can be a little confusing choosing a replacement or the best fan for your application.

Many radon fans have similar performance characteristics. I have personally installed hundreds of radon fans, mostly Fantech, RadonAway and Tjernlund manufactured brands. Originally I used mostly Fantech from 2004 through 2012 then due to poor quality control and increasing warranty problems I switched primarily to RadonAway which are the main radon fans I use now.
