The Saunum Air 5 combines three systems in one assembly:

• Traditional electric sauna heater
• High-capacity stone basket
• Integrated climate-equalizing air system

The telescopic intake draws hotter air from the ceiling area. The system blends this air with cooler air from the lower part of the cabin and returns the mixed air beneath the bench area.

This circulation helps:

• Reduce extreme temperature stratification
• Create more consistent head-to-foot temperatures
• Distribute heat across opposing seating areas
• Produce a gentler perceived temperature without eliminating traditional heat
• Distribute steam more evenly after water is applied to the stones
• Support cabin drying after use

The climate equalizer offers three fan-speed settings through the AirIQ control.

• Published Saunum Air 5 room range for the stainless open-basket version: Approximately 106–212 cu. ft.
• Published room range for some Nordic Black solid-body versions: Approximately 106–177 cu. ft.
• COMO 4-180 interior volume: Approximately 166 cu. ft.
• The physical room volume falls within the published Air 5 range
• Effective heater sizing must also account for the glass door and any uninsulated surfaces
• Heater finish and final adjusted room volume must be confirmed before ordering
• The final Saunum-approved configuration takes precedence over nominal volume alone

• AirIQ temperature adjustment range: 104–194°F / 40–90°C
• Suitable for traditional high-temperature sauna use
• Water may be applied to approved sauna stones to create leil
• Approximately 110–130 lb. stone capacity supports sustained heat and steam production
• Heat-up time depends on ambient temperature, ventilation, heater finish, glass exposure, and electrical conditions
• Insulated ceiling elements support heat retention
• 40 mm ThermoWood® walls provide thermal mass and structural stability
• Saunum air circulation helps reduce concentrated ceiling heat and colder floor-level air
• Multiple bench levels still provide selectable temperature zones
• The AirIQ control manages target temperature, session time, and climate-device speed

The Saunum AirIQ Wi‑Fi control is included as the system’s operating interface.

Features include:

• Wi‑Fi connectivity
• Saunum AirIQ mobile-app pairing
• Remote system management
• Temperature selection from 104–194°F

Optional lighting configurations may include:

• LED lighting beneath the benches
• LED lighting behind the upper backrests
• LED lighting behind upper and lower backrests
• White or color-adjustable illumination
• Independent lighting control
• Integration with the selected system-control arrangement where compatible

Lighting is separate from the Saunum heater and AirIQ control unless specifically included in the final system.

The Saunum climate equalizer and the cabin ventilation system perform different functions.

Saunum Climate Equalization

• Recirculates air already inside the sauna
• Draws hot air from the ceiling level
• Draws cooler air from the lower cabin
• Blends the two air layers
• Returns mixed air beneath the bench
• Offers three fan speeds
• Supports more even temperature and steam distribution
• Can assist with drying after use

• Ceiling-mounted ventilation inlet included with the Leil cabin
• Designed for connection to the building’s ventilation system
• Supplies or exhausts fresh air according to the final mechanical design
• Saunum internal air circulation does not replace required fresh-air ventilation
• Fan, ductwork, external grilles, exhaust equipment, and HVAC labor are not part of the standard cabin
• Final intake and exhaust positions must be coordinated with the Saunum heater
• Ventilation must not interfere with the heater’s ceiling intake or lower air outlet
• Final ventilation design should be approved before assembly

• Indoor installation only
• Requires a stable, level, load-bearing finished floor
• Floor must support the cabin, heater, stones, occupants, and surrounding construction
• No finished floor pan or floor drain is identified as part of the cabin kit
• Site flooring should be heat resistant, moisture resistant, and cleanable
• Waterproofing, tile work, drainage, and floor transitions are site-preparation items
• Plumbing is not required for normal operation
• Water for the sauna stones is applied manually
• Any required drain must be planned according to local code and intended cleaning practices
