The new Airtronic family is the logical further development of the wildly successful Eberspaecher air heater. With its robust components and the latest control system, the Airtronic now features both functional expansions and a longer service life. A new brushless motor has extended service life to 5000 hours and its quieter. The fuel metering pump acoustics are also improved. This is a very nice heater!

The 2019 Airtronic M2-D4L also has altitude adjustment built-in. No more need for additional module.
