Air Compressors - Trucks

Energy-efficient on all road types:

Air compressors with pre-chargers


Traveling economically and saving the environment at the same time. Auxiliary units such as air compressors in trucks and buses contribute significantly to this. Only from Voith: two-stage compression with inter-cooling system. This results in significantly reduced power uptake during transport operation.

And your vehicle is much more fuel-efficient. A special system even lowers fuel consumption while idling, without complex decoupling of the compressor.


Advantages you will enjoy every day:

  • Increased energy efficiency:
    • - Fuel consumption reduced by as much as 1.0 l/100 km
    • - Energy recovery possible in braking and coasting modes
  • Better air quality: longer service life of the air system
  • Significantly longer duty cycles: up to 85%
  • Higher pressure level: Operation above 15 bar possible


Principle of operation

Engine oil does not "crack" - lower fuel consumption

In the non-transport mode, the newly developed idle system SLS will significantly reduce fuel consumption. Lower temperatures reduce the load and avoid cracking of the engine oil. Less damaging by-products reach the vehicle air system.

one-stage series air compressor and two-stage Voith air compressor



Through the two-stage compression and the unique intermediate cooling, the system requires far less power during transport mode. The compression temperature in both cylinders is lower than 250°C. Resulting in greater operating time and thus, greater transportation power per hour with the same engine capacity.

  • Air flows through the suction chamber into the 1st level.
  • Pre-compressed hot air is cooled in the intermediate chamber, drawn in from the 2nd level and compressed to the end pressure.


The portfolio covers pre-charged twoand three-cylinder air compressors made from gray-cast iron or cast aluminium.
