Powerhouses up to 600 cfm

Future-ready powerhouses that thrive in extreme conditions

Our towable portable compressors in the 375 to 600 cfm class can easily handle ambient temperatures of up to +122 °F and can be also be equipped for sub-zero conditions below 14 °F. With their advanced systems and engine controls, they are also exceptionally efficient – which benefits both the environment and your wallet.

  • Maximum pressures up to 205 psig
  • Optional compressed air treatment
  • Optional GPS fleet management

Your advantages

  • Unrivalled availability and efficiency:
    The SIGMA CONTROL MOBIL or SIGMA CONTROL SMART controller ensures optimized compressed air availability and fuel efficiency using state-of-the-art electronic engine management.
  • Eco-friendly – now and tomorrow:
    "Low-Emission Zone MOBILAIR" means: minimal toxic emission values compliant with stringent European Stage IV (model M125) emissions standard (M125 and M171).
  • Intuitive three-button operation:
    Kaeser places great emphasis on user-friendly control. Users therefore avoid costly downtime and steep learning curves.

Our compressor powerhouses in detail


The compressor controller of the future


By accessing electronic motor management, the SIGMA CONTROL MOBIL system optimizes compressed air availability and fuel efficiency. The system is both shock and vibration proof corresponding to IP 65 electrical protection.
Its functions include operational monitoring as well as precise system diagnostics.

User-friendly operation saves time

The highly intuitive user operation means that only three buttons are needed to operate the entire system.
In addition, the automatic monitoring feature can shut the compressor down as required. 

Precise pressure settings save fuel

Using the arrow keys, system pressure can be precisely adjusted in 1.5 psig increments on the SIGMA CONTROL MOBIL's display.
This not only enhances flexibility but, in combination with the electronic inlet valve control, also achieves significant energy savings - especially when operating in partial load.

NEW M125 – Impressive power and efficiency
M125 series: compact, flexible and powerful.

The M125 opens up a whole new world of variable pressure control!

The Mobilair M125 portable rotary screw compressor is built for many applications including sand blasting, pavement breaking, and general air tool use. These units are well suited for rental houses, repair trucks, and railroads.

Heavy-duty diesel engine complies with Final Tier 4 emission standard. 10 micron engine air filter with maintenance indicator.

The integrated SIGMA CONTROL MOBIL controller enables simple and intuitive machine operation. Moreover, this versatile controller also provides information relating to operating data and indicates when maintenance is due.

Real-time data via GPS

MOBILAIR fleet management

An optionally available GPS/GSM modem (standard with M500-2) discretely integrated into the unit provides the user with online information regarding technical status of the machine. Should the user need to be alerted to an issue, the system actively reports it with a diagnostics check.
In addition to current operating hours and position-fixing, the system also helps by providing valuable data for compressor load evaluation and maintenance planning.
