The radon fan is the heart of the sub-slab depressurization system. From fans that draw 20 watts to 300 watts of power, and expel 120 CFM to over 500 CFM of air, there are a variety of fans to fit a sub-slab depressurization system.
Which fan is the right fan?
That’s a key outcome of the diagnostic investigation. While a higher wattage fan might lower the radon levels, a lower wattage fan could be capable of similar radon reductions with less power draw and noise. At CSL Radon Mitigation Inc. we don’t guess. Matching the radon fan to the sub-slab is a science. Our goal is to identify the right fan for each installation.
