RADON SUCTION | H. Östberg

RADON SUCTION Updated: 2026-05-20

A radon suction system may consist of a duct fan (in this example an IRE 160 C1 EC) equipped with insulation and speed control for indoor installation.
Alternatively, one of our roof or wall fans (TKC, TKS, TKV, RS) can be used for outdoor installation.
Radon suction should be installed with a speed controller, manometer, and pressure sensor with alarm to monitor pressure differences.
A radon suction system has low operating and installation costs and reduces indoor radon levels by 10–80%.
