Description
The Saunum Air L 15 Stainless Steel Sauna Heater is an advanced sauna heating system designed to create a perfectly balanced sauna climate. Featuring Saunum’s revolutionary patented air mixing technology, this heater eliminates uneven heat layers commonly found in traditional sauna rooms.
In a typical sauna, hot air rises to the ceiling while cooler air settles near the floor. This often causes the upper body to feel too hot while feet remain cold. Saunum solves this issue with an innovative climate equalizing system that blends cooler oxygen-rich air from the floor with hot air from the ceiling and redistributes it evenly throughout the sauna.
This creates a more comfortable sauna environment where heat and oxygen levels are balanced from head to toe.
The heater also features a massive 198-pound stone capacity, producing soft, luxurious steam when water is poured over the stones. Integrated Himalayan salt spheres enhance the sauna atmosphere by releasing natural salt ions into the air.
With its elegant stainless steel Scandinavian design, the Air L 15 combines modern aesthetics with high-performance sauna engineering, making it ideal for larger residential or commercial sauna installations.

Air Mixing Climate Equalizer System
The Saunum Air L heater features a patented air blending system designed to solve one of the biggest discomforts in traditional saunas.
The system works by:
• Drawing hot air from the ceiling
• Pulling oxygen-rich air from the floor
• Mixing both air streams inside the heater
• Distributing the balanced air evenly throughout the sauna
Benefits include:
• Eliminates cold feet
• Even heat distribution
• Improved breathing comfort
• Balanced oxygen levels in the sauna
This technology creates a sauna climate that is far more comfortable than traditional heaters.
Himalayan Salt Therapy System
The Air L 15 integrates a Himalayan salt reservoir inside the airflow system.
As air circulates through the heater, it passes over the salt spheres, distributing natural salt ions throughout the sauna.
Benefits include:
• Improved air quality
• Enhanced sauna wellness experience
• Optional aromatherapy compatibility
The tray is removable and allows easy replacement of salt spheres or addition of aromatherapy scents.
Stone Capacity & Steam Experience
The Air L 15 holds 198 pounds of sauna stones, creating a powerful thermal mass.
Large stone capacity provides:
• Softer and more comfortable heat
• Longer-lasting steam

198 lbs of sauna stones (6 boxes) sold separately.
