Easy Connect e16 brings demand-controlled comfort to decentralized residential ventilation. The Connect controller manages up to 16 devices and sensors across up to 4 zones, displays air quality, humidity and temperature on the screen, and is easy to configure via Bluetooth with the free inVENTer Mobile app. Note: The controller has no built-in humidity/temperature sensors; matching sensors are available separately.

• Wireless Connect control for up to 16 devices/sensors
• Up to 4 independently adjustable ventilation zones
• On-screen display: fan data, air quality, humidity, temperature
• Bluetooth setup and control via inVENTer Mobile app
• Optional outdoor sensor enables dew-point control and summer mode

The iV14-Zero is inVENTer’s quietest decentralized ventilation system. Thanks to the patented sound-insulation concept with Inventin® and the XENION® fan, it ventilates whisper-quietly and energy-efficiently. The ceramic heat store achieves up to 87% heat recovery, while onboard intelligence protects against winter chill and wind pressure—optionally with Connect control and app.

• Whisper-quiet: own noise 13–29 dB(A), sound reduction 48–56 dB
• Up to 87% heat recovery (ceramic core + inVENTron® airflow guidance)
• XENION® fan with temperature guard & wind-pressure stabilization (DIN EN 13141-8 S3)
• Fast installation with Simplex wall module; Corner/Nordic exterior options
• Smart control: MZ-Home/Easy Connect or wireless Connect + mobile app (optional)

The R2 generates reliable sub-slab underpressure to lower indoor radon levels. Its energy-efficient EC blower, adjustable speed and automatic “Flow Mode” tailor capacity to soil conditions and duct runs—suitable for small homes up to larger Projects.

• EC blower: high pressure with low power draw
• Flow Mode keeps target airflow constant automatically
• 50 mm spigot: smaller core hole, minimal building impact
• Airflow alarm for low/no flow conditions
• External control panel (magnet/wall mount), digital display, quick tool-free filter change

T2 ES is the smallest yet most powerful turbine in the ES family, built for small to mid-size drying projects. Delivering up to 180 m³/h, it features constant-flow control, self-regulating operation under high load, and low noise. Stackable, robust, and prepared for remote monitoring with SuperVision®.

• Airflow up to 180 m³/h, static pressure up to 260 mbar
• Constant-flow mode keeps airflow regardless of back pressure
• Self-regulating at high load – no manual reset required
• Low noise (48 dB(A) max), compact & stackable
• ES ecosystem: inter-device communication, SuperVision®-ready

The T4 ES is the largest turbine in the ES range—engineered for both small and large drying tasks. Delivering up to 300 m³/h, it features constant-flow control and self-regulating operation for fast, efficient and quiet results. Robust, stackable and prepared for SuperVision® remote Monitoring.

• Airflow up to 300 m³/h, pressure up to 260 mbar
• Constant-flow keeps airflow regardless of back pressure
• Self-regulating under heavy load – no manual reset
• Low noise (48 dB(A) max), robust & stackable
• ES ecosystem: device-to-device communication, SuperVision®-ready
