In wall underfloor radon fan designed for competent DIYers or for a builder/electrician to fit. The in-wall under-floor ventilation fan is an ideal solution to high radon levels in houses/buildings with suspended floors. A 150mm circular hole needs to be cored in the sub-floor wall before fitting this kit. Once connected to the mains the system can reduce radon levels dramatically. No need for pulling up the floors or major building work.
The unit is highly energy efficient, using the latest fan and unit design to reduce electrical usage to only 18 watts of energy. The unit comes complete with extension tube (to extend outlet into the under-floor cavity) and instructions.
