    • Maximum user comfort thanks to digital control

Air Supply Systems for Tractors

The hydraulically powered S1000 compressor is used on tractors where tyre inflation using the tractor’s standard air compressor takes too long. The unit especially features a compact design and a minimal power requirement.

  • Rotary screw compressor with oil radiator: 7.5 bar (110 psi)

  • Powered by an axial piston motor

  • Effective delivery performance: 800 – 1000 L/min at 2 bar (29 psi) resistance

  • Oil capacity: 5L

  • Oil requirement of the hydraulic motor: approx. 35 L/min
