Zehnder ComfoValve Luna supply air valves supply fresh air for comfortable indoor ventilation. Special emphasis is put on user comfort due to its optimized outflow behavior for draught-free ventilation and very low-sound level. The valve is designed to remain at a low fixed height while having 25 adjustable air volume positions, is UV- and scratch-resistant thanks to high-quality materials, and blends harmoniously into any interior. A specially developed lock avoids inadvertent modification of the air volume setting, another benefit for users. Contemporary design combined with intelligent functionalities enable optimum performance.
