Compact oil-free reciprocating compressor systems: AIRBOX and AIRBOX CENTER

Ready for connection, quiet and exceptionally durable

Compact AIRBOX and AIRBOX CENTER units featuring air receiver, dryer and optional filters are delivered ready for connection and immediate operation. Controlled by the SIGMA CONTROL 2 electronic controller, the integrated reciprocating compressor produces quality oil-free compressed air.

Technical parameters for AIRBOX and AIRBOX CENTER units are as follows:

  • Pressure: 7 / 10 / 12.5 bar
  • 0.77 – 0.90 m³/min
  • Motor power: 7.5 kW

AIRBOX and AIRBOX CENTER compact oil-free reciprocating compressor systems are perfectly suited to applications requiring clean compressed air, such as those found in laboratories, the pharmaceutical industry and the food & beverages industry.

The benefits

  • 24/7 compressed air availability – even at high temperatures:
    Thanks to an innovative cooling design for the compressor block and drive motor, AIRBOX and AIRBOX CENTER units can be operated at 100 % duty cycles in ambient temperatures up to +30 °C.
  • No additional soundproofing required:
    40 mm-thick sound insulation, cooling airflow with multiple bends, an acoustically decoupled compressor block, the perfectly-matched length of the inlet air line and highly effective soundproofing boxes allow installation directly at the work station – with no need for additional sound protection measures.
  • Maintenance – a thing of the past:
    The oil-free nature of the compressor, as well as the maintenance-free 1:1 direct drive fitted in AIRBOX and AIRBOX CENTER units, means you will hardly ever meet our service staff! However, if the need for a service visit does in fact arise, the air filters and inlet filters are easily accessed by simply removing the large enclosure panels.
