Mitigation kit - RN1 Fan - Do-It-Yourself - Sub Slab Depressurization

Regular price $440.00 Sale

This kit contains all the difficult to find bits to complete your own Do-It-Yourself Active Slab Depressurization radon mitigation system and Fantech's newest and largest fan. The Fantech EC line of fans differ from the others with variable speed controls.  Variable speed control is especially helpful for the Do-it-yourselfer that does not have the instrumentation to properly size the fan helping with noise reduction and energy efficiency.

The RN1 is the smallest and quietest of the Fantech radon fans.

These systems have demonstrated up to a 99% reduction in indoor radon levels. Just add pipe, pipe cement and some sweat equity, and you can start breathing safe again.

Health Canada strongly recommends hiring a certified C-NRPP radon mitigation professional.  Professionals can properly determine airflow and fan sizing requirements, seal radon entry paths, identify potentially deadly back-drafting situations, and properly seal building envelope penetrations. 

However - if hiring a pro is not an option, following the DIY manual included in this kit gives you a good chance at constructing a radon mitigation system that is both safe and effective.  Be sure to consult with a pro if you have any questions relating to the safety of your system.  

This kit is to be used with 4" schedule 40 PVC or ABS pipe.
