Webasto Air Top Diesel Heater

Air Top

Enjoy precise and constant temperatures inside your motorhome at any altitude and in any weather conditions. 

Webasto air heaters provide continuous heating power output via stepless modulation. The heater operates quietly while consuming minimal electrical power and fuel. Available installations include outside or inside the vehicle. 

The integrated altitude sensor constantly ensures an optimal combustion process in altitudes up to 2,200m – under lower air pressure and with a lower oxygen ratio. The Air Top Evo models feature an in-built air pressure sensor as standard. The Air Top 2000 STC model is offered with an optional altitude switch. Please contact us first if this is required.
