The Helios KWL-MZB 6+1−75÷125 R90 is a compact MultiZoneBox that unites volume flow regulation, sound insulation, and air distribution in one advanced unit — ideal for both supply and extract air applications. This model features a 90-degree right-side duct connection for enhanced installation flexibility. It integrates seamlessly with Helios central KWL ventilation systems to deliver ultra-quiet and need-based ventilation throughout the building. Each zone operates independently with its own airflow control, tailored to user preferences. The system can be managed using a discreet ECO panel, a modern touch controller, or an optional VOC sensor for automatic, air quality-based ventilation adjustments
