Oil-free reciprocating compressor compact unit: AIRBOX


Ready for connection, quiet-running and exceptionally durable

The AIRBOX compact unit is ready for connection and immediate operation. The integrated reciprocating compressor produces quality oil-free compressed air and features the SIGMA CONTROL BASIC electronic controller.

The technical parameters for the AIRBOX are as follows:

  • Pressure: 7 / 10 / 12.5 bar
  • Flow rate: 0.25 – 0.90 m³/min
  • Motor power: 2.2 – 7.5 kW

The AIRBOX oil-free reciprocating compressor compact unit is perfect for applications requiring pure compressed air, such as in laboratories, in the pharmaceutical industry and in the beverage and food industry.

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.
