Ventilate quietly, save heat, and secure healthy indoor air: the inVENTer iV14-Zero combines acoustic comfort, energy efficiency, and simple operation in one decentralized unit. The patented sound-insulation concept with the high-performance material Inventin® minimizes exterior and own noise—down to an almost inaudible 13 dB(A) in whisper mode. At the same time, the XENION® technology ensures even airflow through the ceramic heat store for up to 87% heat recovery.
What sets the iV14-Zero apart
- Patented sound insulation: special Inventin® lining delivers maximum quiet without sacrificing airflow.
- XENION® fan: the integrated temperature guard prevents room cooling in winter; wind-pressure stabilization keeps the set speed constant even in gusty locations (S3 classification per DIN EN 13141-8).
- inVENTron® dual airflow guide: straightens turbulence, optimizes the ceramic core flow, and boosts efficiency.
- Easy installation: the Simplex wall-in system speeds up rough-in; Corner (reveal) and “Nordic” exterior finishes enable discreet façades.
- Smart control: from basic multi-zone controllers (e.g., MZ-Home) to the wireless Connect system. With the IB Connect interior cover, sensor-driven profiles and control via the inVENTer Mobile App become possible.
Applications & benefits
- Bedrooms and living spaces in new builds and retrofits—especially where low noise is critical.
- Demand-controlled fresh air supply with high energy recovery.
- Discreet façade solutions for heritage projects (Corner) or brick façades (Nordic).

Notes
For best results, plan devices in pairs (alternating supply/extract). The exact configuration depends on building layout, room use, and façade. We’ll be happy to advise on the right controller, exterior finish, and Simplex Installation.
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).
