Does Radon Mitigation System Work With the FixOasis Fan?
Worth it, with a layout check

Worth it or skip it?
Worth it if
- Your planned mitigation layout uses the listed 4-inch fan connection or stated 3-inch PVC/ABS connection and has 120-volt power.
Skip it if
- You haven't checked the pipe route, connection size, or 120-volt supply for your planned mitigation system.
Key facts
Listed electrical supplyThe fan is listed for 120 volts and 85 watts; confirm your available supply matches.
Described connectionsThe seller identifies a 4-inch fan and couplings said to fit 3-inch PVC/ABS; verify your pipe layout.
A plausible fit, not a guarantee
Choose it when the planned layout and 120-volt supply match the listed configuration. Have a qualified radon professional assess the design and test before and after installation; 260 CFM does not guarantee a particular reading.
Buy on AmazonWhen the pipe meets the fan
Your mitigation pipe reaches the FixOasis fan, its cord meets a 120-volt supply, and the exhaust route is ready for assessment.
A dedicated mitigation exhaust
This dedicated FixOasis Ra-Fan/R-Fan exhausts radon-containing air through mitigation piping to create negative pressure, according to the seller. The listed setup uses a 4-inch fan with 4-to-3-inch couplings for stated 3-inch PVC/ABS connections—not a general room fan.
Choose by pipe size, power, and system design; the listed airflow alone cannot establish your building’s result.
