It carries the same defining technology as the stainless steel Air L 10 SS - the fan-driven air mixing system that eliminates temperature stratification, the Himalayan salt reservoir that carries salt ions through the circulating airstream, the active sauna drying function, and six distinct sauna bathing styles - in a matte black steel finish that suits darker cedar, thermally modified wood, and contemporary sauna interiors. The black model holds 180 lbs of stones (6 boxes, sold separately), and a Saunum AirIQ WiFi control (sold separately) is required for operation.\u003c\/p\u003e\n\u003ch4\u003eThe patented air mixing system - consistent heat and oxygen from floor to ceiling\u003c\/h4\u003e\n\u003cp\u003eIn a conventional sauna, heat stratifies predictably: the heating elements warm the adjacent air, hot air rises to the ceiling, and the floor and lower bench level remain significantly cooler. The Saunum Air L's integrated fan draws cool, oxygen-rich air from the floor of the sauna room, blends it inside the climate equalizer with hot air from the ceiling zone, and distributes the mixed airstream evenly throughout the room. The practical result is a sauna environment where the temperature difference between the floor and the ceiling is substantially smaller than in a conventionally heated room, where oxygen levels are more consistent at every height, and where bathers at every bench level experience meaningful heat rather than only those on the upper bench. No other sauna heater in this catalog offers this capability.\u003c\/p\u003e\n\u003ch4\u003e180-lb stone capacity and Himalayan salt reservoir\u003c\/h4\u003e\n\u003cp\u003eThe black Air L 10 holds 180 lbs of sauna stones (6 boxes, sold separately) - a large stone load that stores substantial thermal energy, produces soft and sustained steam, and provides the heated surface area that the air mixing system distributes through the room. Within the stone airstream, 7 Himalayan salt spheres (included) sit in the integrated reservoir so that salt ions are carried throughout the circulating air with every session. The matte black exterior of this model suits dark interior palettes: dark cedar, thermally modified ash or alder, black-framed glass panels, and charcoal or ebony-stained bench wood. The choice between the black and stainless models is purely aesthetic - all technical specifications are the same.\u003c\/p\u003e\n\u003ch4\u003eActive sauna drying and six bathing styles\u003c\/h4\u003e\n\u003cp\u003eBecause the Air L has an integrated fan, that fan continues working after the session to dry the sauna room - reducing moisture accumulation in the wood and lowering humidity in the structure between uses more quickly than passive ventilation alone. For frequently used sauna rooms, shorter drying time between sessions is a meaningful practical benefit. The AirIQ WiFi control (sold separately) enables six distinct sauna bathing styles by adjusting the balance of heat, airflow, and humidity: Finnish sauna, Russian banya, steam sauna, herbal sauna, aroma sauna, and relaxation mode. Up to 3 preferred configurations can be saved as presets for one-tap session starts from the Saunum app.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"sl-hook\"\u003e10kW floor-standing sauna heater with patented climate equalizer for rooms from 283 to 494 cubic feet.
