Radon Reduction Inline Fan – 125 mm / 490 m³/h
Elevated radon levels in a basement or ground floor are not something you can ignore. When your radon detector shows increased concentrations, it’s time for decisive action – reliable extraction of radon from beneath the house to the outside.
This professional radon reduction inline fan is designed exactly for that purpose: radon from the sub-slab collection point is safely directed outdoors, away from windows and doors. Efficient, quiet and energy-saving – for long-term protection of your home.
Why choose this radon extraction fan?
- Specifically designed for radon mitigation – for extracting gases from under foundations
- High airflow – 490 m³/h with a 125 mm duct diameter
- Powerful yet quiet – only around 43 dB(A)
- Energy efficient – maximum consumption 65 W
- Optional speed control – adjust airflow to your system’s needs
- Suitable for indoor and outdoor installation – IP44 protection class
- Mounting bracket included – easy installation
How does a radon mitigation system work?
The foundation of radon mitigation is the **radon sump or collection point** created under the building. This becomes a low-pressure point where soil gases – including radon – naturally accumulate.
From this sump, radon is extracted through a pipe, which is connected outside the building to the inline fan. The fan creates negative pressure, preventing harmful gases from entering living spaces through cracks and openings. Instead, they are vented above the roofline or at least above the eaves, safely away from living areas.
Important: For designing a radon sump and pipe system, professional assistance is recommended according to current radon mitigation guidelines.
When should you consider installing a radon fan?
Normal radon levels are around 20 Bq/m³. When measurements show elevated concentrations above recommended limits and simple actions (ventilation, sealing cracks) are not enough, installing a radon extraction fan is often the most effective solution.
The inline fan functions as the key component of an active sub-slab depressurization system, providing long-term reduction of radon levels in living spaces.
Easy installation and operation
- Install the fan on a 125 mm duct system connecting the radon sump to the exhaust outlet
- Attach it to a wall or stable surface using the included mounting bracket
- Connect to a standard 220/230 V AC, 50 Hz power supply
- If needed, adjust fan speed (speed controller available separately in our store)
The compact and robust housing makes the fan suitable for basements, utility rooms, or exterior wall installations.

Order your radon reduction inline fan
If your radon measurements show elevated concentrations, it’s time to take action. Order the radon reduction inline fan and ensure the gas is safely vented outdoors, away from your home.
Radon is natural, but the risk it brings is not inevitable. Take an active step toward a safer living environment.
