HOW QUIET CAN IT BE?The inVENTer sound insulation concept
iV-Zero Connect
- Whisper mode with 10 dB(A) thanks to Xenion fan
specially designed for decentralized ventilation. - Easy installation with simplex wall installation kit.
- Sensors adjust ventilation cycles, preventing indoor spaces from cooling down in winter.
- Pressure stabilizer ensures smooth operation even in strong winds.
- Wireless control with inVENTer Connect.
- Patented Inventin® sound insulation lining.
Inner cover Silence
- Noise reduction without reducing the
air flow rate. - The ventilation unit’s own noise is reduced by up to
4 dB(A). - Available for ventilation systems with Flair or Connect interior panels.
- Retrofitting possible for current and older
systems. - Discreet and closed design.
Core silencer
- Reduces sound pressure levels by up to 8 dB(A)
and provides effective protection against external noise. - Compact insert allows quick &
easy retrofitting from the inside. - The spacers on the outside ensure
reliable airflow. - Made from the patented
Inventin® sound insulation material.
Available from February 2026: Corner external closure
- The exterior finish blends inconspicuously into the window reveal.
- Available in three sizes for different
sound insulation requirements. - Additional sound insulation thanks to SSE sound insulation
inserts in the duct. - Suitable for standard inVENTer
ventilation systems.
