Saunum Air L 15 – Stainless Steel
Overview
The Saunum Air L 15 is a unique heater with a sauna climate regulating system that is ideal for creating an extraordinary sauna session in a more intensively used sauna. The large stone volume of the Saunum Air L 15 and the patented air-blending system ensure exceptional steam that is soft and long, and evenly distributed throughout the sauna.
Key Features
- Revolutionary Air Mixing Technology – No more cold feet! No other sauna heater has Saunum's patented air blending system, which mixes cooler, oxygen-rich air from the floor with hot, oxygen-poor air off the ceiling and distributes it throughout the room for a more even temperature and better breathability. Saunum ensures that heat and oxygen are more consistent from head to toe.
- Scandinavian Design – With its elegant stainless steel finish, Saunum combines contemporary Scandinavian design and premium-quality materials.
- Massive Stone Capacity – Stones are the heart of a Nordic sauna. Greater stone capacity results in softer, more even heat, and can produce more luxurious steam. The Air L boasts a massive 190 pound stone capacity (required 6 boxes sold separately).
- Himalayan Salt Reservoir – Himalayan Salt Spheres are positioned within the air stream so that salt ions are propelled throughout the sauna to deliver health benefits more effectively.
- Dry your Sauna – Go ahead, toss water onto the rocks! Saunum is engineered for water-tossing, and when you're done enjoying the steam, the patented fan system will conveniently help dry your sauna.
- UL Certification – Safety and reliability are priorities at Saunum, and each product is engineered to exceed strict UL standards.
- Available Aromatherapy – Add another sensory layer with Saunum's optional aromatherapy system, which infuses aroma into the steam to further transform your experience.
- For sauna rooms from 530 to 812 cu. ft.
