Your advantages

  • 24/7 compressed air availability – even at high temperatures:
    Clever air flow design ensures optimal compressor block and motor cooling, which allows 100 % duty cycles and reliable operation in ambient temperatures up to 30 °C.
  • No need for additional soundproofing:
    40 mm-thick soundproofing, cooling air flow with multiple bends, an acoustically decoupled compressor block, the optimised length of the inlet air line and effective soundproofing boxes enable installation adjacent to workstations – with no need for additional sound protection measures.
Energy cost savings
Life-cycle costs

Premium quality IE3 motors ensure outstanding performance and efficiency; they reduce reduce energy losses, on average, by 45 % compared to conventional motors. resulting in significantly lower power consumption.
