ComfoValve Luna S125

    The Zehnder ComfoValve Luna S125 supply air valve provides comfortable indoor ventilation. Due to its optimised outflow behaviour (Coanda effect), the valve meets the perfect requirements in terms of comfort and noise, and is rounded off by a discreet, appealing design. Zehnder ComfoValve Luna S125 is suitable for installation in ceilings and walls. Due to an integrated rubber seal, the valve can be installed easily and achieves an air-tight fit. The valve can be adjusted for the required air volume using the "Flow Cone", a restrictor unit with optimised flow, without requiring any tools; this saves time during installation and start-up. The air volume setting is secured using the lock specially developed for this purpose; the setting therefore cannot be modified inadvertently. The valve protrudes just 30 mm in spite of the various volume flow settings, and it blends harmoniously and discreetly into any interior. Coming soon

    Focus benefits

    Increased comfort

    The ComfoValve Luna provides exceptional airflow with minimal noise. We’ve designed this unit to utilize the Coanda effect, which is when air flows over a curved surface. This reduces draughts and noise, leading to a more pleasant indoor environment.
