The Saunum Air L 15 is a high-output sauna heater designed for large residential and commercial sauna environments where consistent heat distribution and airflow control are essential.
At the core of the system is Saunum’s patented air blending technology, which continuously mixes cooler, oxygen-rich air from the lower portion of the sauna with hotter air near the ceiling. This eliminates extreme temperature differences and improves overall air quality for a more balanced and breathable sauna environment.
The integrated climate equalizer ensures that heat and oxygen are distributed evenly throughout the entire space, allowing for longer, more comfortable sauna sessions without overheating the upper body or leaving lower areas under-heated.
With a stone capacity of up to 265 lbs, the Air L 15 produces soft, consistent steam and supports a more refined Nordic sauna experience. The unit is engineered for water-tossing (löyly) and includes an internal airflow system that helps dry the sauna after use.
Available in both black steel and stainless steel finishes, the Air L 15 is built for durability, performance, and high-volume sauna applications.
