Description
The air tunnel sits vertically in the centre of your Cliff or Steel heater, built into the stone core as you layer the stones. By keeping air moving through the heart of the heater, it helps your sauna heat more efficiently and hold a more even temperature, while supporting reliable operation and helping to protect the heating elements. It also reduces the volume of stones the heater needs. As a genuine HUUM part made to the original specification, it restores your heater to full performance with a precise, dependable fit.

- Compatibility: HUUM Cliff and HUUM Steel electric sauna heaters
- Material: high-quality stainless steel

Fitting your air tunnel
- Position the air tunnel vertically in the centre of the heater as you layer the stones.
