Description

The Harvia Air Guide directs airflow away from the sauna heater's temperature sensor to deliver accurate temperature readings for a safe sauna experience. It measures 10.8"W (27.5 cm) x 7.9"D (10 cm) x 0.4"H (1 cm). Supplied in stainless steel.

Also known as a supply air diffuser, the Air Guide is used when the sauna heater's temperature sensor is placed near the sauna's supply air valve. The flow of air from the valve cools the air by the time it reaches the temperature sensor, giving an incorrect reading. As a result, the sauna heater may become too hot. The Air Guide directs the air away from the sensor for an accurate reading every time.

  • Durable stainless-steel construction designed for ceiling installation.
  • Directs air away from your sauna heater's temperature sensor for accurate readings.

FAQs

Where do the sauna air inlet and outlet go?

Inlet low, near the heater; outlet high on the opposite side. That is the pattern that moves air through the room. Without it the sauna stratifies — cold bottom bench, stifling top, and a flat löyly no matter how hot the stones get.
