RADON EXTRACTOR | H. Östberg

RADON EXTRACTOR Updated: 2025-06-25

A Radon extractor can be e.g. a duct fan (in this case IRE 160 C1 EC ) which is equipped with insulation and is speed controllable for indoor use.
You can also choose one of our roof or wall fans (TKC, TKS, TKV, RS) for outside mounting.
The Radon extractor should be mounted with a speed controller, manometer and pressure sensor with an alarm to control the differential pressure.
A radon extractor has low operating and installation costs. It reduces the radon content in the air by 10-80%.
