Basement radon reduction—quiet and efficient
In many homes, elevated radon starts in the basement. The iV-Smart+ Sylt lowers concentrations where they originate by providing continuous air exchange and gentle pressure equalization—exhausting radon-laden air while supplying fresh air, without constant window ventilation and with excellent energy efficiency.
Engineered for below-grade
A branch piece with condensate drain routes the exterior duct up to ground level. The louvered exterior cover is driving-rain resistant, snow-safe and pest-resistant, blending discreetly into the plinth area (colors: white, grey, beige).
Quiet & efficient
The XENION® fan ensures uniform flow through the ceramic heat store; the inVENTron® dual guide straightens the airflow. The result is up to 87% heat recovery with outstanding acoustic comfort—ideal for finished basements.
Easy installation & flexible control
Install quickly with the Simplex wall-in system. Choose wired controllers (sMove, Pure, MZ-Home) or go wireless with the Connect ecosystem, IB Connect interior covers and mobile-app control.

Radon ventilation – simple, efficient, tailored
With inVENTer’s decentralized radon ventilation systems, you can lower basement and ground-floor radon levels through continuous fresh-air exchange and gentle pressure equalization. Our heat recovery ventilation (HRV) keeps warmth indoors while quietly exhausting radon-laden air—an energy-efficient, low-noise way to improve indoor air quality.
Benefits at a glance
– Effective radon reduction via continuous ventilation & pressure relief
– Ideal for basements, semi-basements and ground-contact rooms
– Energy-saving HRV, whisper-quiet operation, optional smart controls
– Easy to retrofit with discreet exterior terminations
– Free ventilation planning: we size airflow, device count, placement and controls for your project
Note: For reliable verification, we recommend continuous radon monitoring before and after installation. Very high radon levels may require additional measures (e.g., sealing or sub-slab depressurization).
