Piston compressors

The hydraulic piston compressor converts the hydraulic power of a mobile machine, vehicle or ship into compressed air.

Piston compressors - hydraulically driven compressor systems for mobile applications

The hydraulic piston compressors in the DYNASET HK series reliably convert the hydraulic power of a mobile machine, vehicle or ship into compressed air. They offer a powerful, compact and highly efficient solution for users who need a reliable compressed air supply in a mobile working environment.

Compared to conventional, large diesel-powered piston compressors, the hydraulic DYNASET HK units are significantly smaller, lighter and easier to integrate. This makes them ideal for use on drilling rigs, tractors, excavators, utility vehicles and other mobile machinery where space, weight and energy efficiency are critical.

The compressors can be fully integrated into the machine's existing hydraulic system and are therefore always ready for use - without additional transport, without a separate motor and without an external power source. Operation is simple, maintenance requirements are low and the entire operation is characterised by high energy efficiency and a reduced CO₂ footprint.
