Introducing the Airtronic 3
Petrol and diesel Airtronic air heaters from Eberspacher ward off the cold in any application. Now in the third Airtronic generation, the four model variants are on an entirely new technological level.
The upgraded combustion chamber, durable brushless motor, integrated altitude sensor, and stepless heating control, provide an unprecedented level of quiet comfort. Maintaining your ideal temperature anywhere you go has never been so convenient.
Reach greater
heights
The integrated altitude sensor guarantees accurate temperature control at elevations of
up to 5,500 meters (18,000 feet).
Stay warm
without a sound
The optimized metering pump, improved brushless motor, and stepless heating control ensures
nearly silent operation.
Spend less
on power and fuel
The new laser-welded combustion chamber and dynamic heating control makes the Airtronic 3 even more effective and fuel-efficient.
