No pollutant emission or dust in the cab

Eberspächer cab pressure system

For a pleasant and safe working atmosphere

Perfect cab climate control for agricultural machines

Combining a filter system with optimally dosed excess pressure keeps the cab air clean. Dust particles and pollutants are filtered before entering the cabin. Excess pressure is created to prevent any external elements from entering the cabin. K Protec can be combined easily with the Eberspächer climate control system and is therefore the perfect addition to cab climate control in agricultural machines. Support your drivers with a cab pressure system from Eberspächer, for a comfortable and safe work environment in a pleasant atmosphere.
