Ross ventilation poles
Humidity which moves from the surrounding environment into underfloor spaces must be carefully removed to prevent both health hazards and structural damage. The Ross ventilation pole is an elegant choice for the ventilation of underfloor spaces, as well as for the prevention of moisture damage in ground-level floors. The Ross ventilation pole can be used as an air inlet for a basement sauna, fireplace or mechanical ventilation system, and is also suitable as a replacement or exhaust air terminal in more sophisticated systems. In addition, Ross ventilation poles can be used together with the ECo 110 radon fan to remove radon gas from subfloor spaces. Watch this video to learn how easy the installation of the Ross ventilation pole is (subtitles in English available). This product selection includes Ross ventilation poles and associated accessories. Find the right product for your needs below.
