Saunum AirSolo 70: a wall mounted climate device that evens out the heat in any sauna
The Saunum AirSolo 70 is a wall mounted climate device that mixes the air in a sauna you already have, whatever heater is in it. It does not make heat; it moves it. A quiet three speed fan draws the hottest air from beneath the ceiling through the top grille. It blends that heat with cooler, oxygen rich air near the floor and sends the mix back out low in the room, so the lower bench stops feeling cold and the steam feels softer. The unit is brushed steel in anthracite gray with a black glass front panel. It measures 17 inches wide and 9 inches deep, and stands 70 inches tall, or 75 inches with the intake grille fitted. That makes it a good fit for a sauna with a ceiling around 7 feet. It weighs 66 pounds.
It plugs into a standard 120 volt outlet and works with any electric or wood burning sauna heater. You choose the fan speed with a turn switch. The box holds the unit, the glass air transfer module, the intake grille, the bottom tray, seven Himalayan salt spheres, and two wall strips for hanging the unit. The salt spheres sit in the tray in the air path. An air deflector, extra salt spheres, and sweet orange, grapefruit, or eucalyptus aroma oils are optional. Taller ceiling? See the Saunum AirSolo 80. The Saunum AirSolo 70 ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
FAQ
How does the AirSolo 70 solve the hot head and cold feet problem?
A quiet fan inside the unit draws the hottest air and steam from just under the ceiling, mixes it with the cooler, oxygen-rich layer near the floor, and returns the blended air low in the room. That evens out the temperature from the upper bench to the floor, so sessions feel gentler on the head and warmer on the feet. Three fan speeds let you tune how much air is moved.
Can I add it to my existing sauna without changing the heater?
Yes, that is exactly what it is for. It is a stand-alone wall-mounted climate device that the page says enhances any electric sauna heater, and the Specifications tab also lists an allowed maximum of 212 F with a wood-burning heater versus 194 F with an electric one. Nothing about the heater or its control changes; the unit simply needs its own low-current 120 V circuit.
What are the dimensions and how is it mounted?
The unit measures 70.4 inches tall, 17.2 inches wide and 8.89 inches deep, or 74.8 inches tall once the air intake grille is fitted, and weighs about 66 lb. It hangs on two included wall strips; the manual wants the upper vent close to the ceiling, the lower edge at least 4 inches off the floor, and no shower head or water spray mounted above it.
Do I need an electrician for a 120 V device?
Yes. The installation manual requires permanent wiring, not a plug, run by a qualified electrician: a 120 V circuit with overcurrent protection and a residual-current device, protective earth, and cable of at least 16 AWG rated for sauna temperatures, entering the housing vertically from below. The Specifications tab lists the supply as 120 V, 60 Hz at well under one amp.
Does running the fan make the bench hotter or cooler?
During a session it makes the room more even rather than hotter overall, and a small cooling damper on the bottom front panel lets you soften the steam; the manual recommends starting with it about one-third open. Do not run the fan while the room is heating or when nobody is inside, because then it does push heat downward and the bench and floor can become uncomfortably hot.
What comes in the box?
The Includes tab lists the heat equalizer body, the air transfer module, the air intake grille with its mounting bolt, a bottom tray, the turn switch, seven Himalayan salt balls, two hanging strips and the installation and operation manual, backed by a 2-year limited warranty for consumer use. The power cable and the electrical work are supplied on site by your electrician.
Are aroma oils included, and what other accessories fit?
Aroma oils are not in the box, but this page offers Saunum aroma oil sets in sweet orange, grapefruit and eucalyptus, each with a reservoir, plus a seven-piece Himalayan salt refill set, under the Sauna Heater Add-Ons selector, and the Saunum Air Deflector under Operating Accessories.
