NEW FOR 2018!
The new Airtronic family is the logical further development of the successful Eberspächer air heater. With its robust components and the latest control system, the Airtronic now features both functional expansions and a longer service life.
The new Airtronic is equipped with automatic altitude adjustment as standard. A new brushless motor has extended the service life to 5,000 hours. This new motor, a modern control system and the use of the latest metering pump technology also improve the acoustics. Furthermore, the new Airtronic uses the pioneering Eberspächer CAN bus technology.

* Use in campers/RVs, boats and ambulances, for example. For long, complex heating-air ducting, e.g. when many meters of heating-air hose must be laid.
** Each component of the heating-air ducting (air hose, curved sections, vents, etc.) has a line guide number. The sum of these line guide numbers must not be greater than the guide number for the heater. The higher the guide number for the heater, the more heating-air ducting components may be connected.
*** The heater is protected against dust in harmful quantities, against powerful water jets under increased pressure and against water during high-pressure/steam jet cleaning (provided it is not in operation).
