Portable compressors with diesel engines

Diesel-driven compressors up to 48.1 m³/min

Compact, powerful and versatile – Performance is more than a promise with diesel-driven MOBILAIR portable compressors from KAESER. As true powerhouses of the MOBILAIR range, these oil-injected portable compressors combine exceptional performance with compact design. 

These versatile machines can be perfectly adapted to meet the needs of the specific application thanks to a wide range of optional treatment components that always deliver the required compressed air quality. Furthermore, the generously-sized fuel tank ensures impressive construction site staying power. When full, the fuel tank has sufficient capacity to last an entire work shift. These versatile portable compressors are equipped as standard to deal with ambient temperatures ranging from -10 to +50°C. Machines are also optionally available for lower ambient temperatures.

The MOBILAIR M135 is exceptionally flexible thanks to its dynamic ‘pV control’. One and the same system can deliver pressures between 5 and 14.5 bar. This makes them ideal for cable blowing and drilling, for blasting work and concrete processing, as well as for providing backup air in opencast mining and industrial applications.

Performance data:

  • Flow rate up to 48.1 m³/min
  • Working pressure up to 15.5 bar

Your benefits

  • Perfect performance even in extreme temperatures:
    These versatile portable compressors are equipped as standard to deal with ambient temperatures ranging from -10 to +50°C. Machines are also optionally available for lower ambient temperatures.
  • Clean and oil-free compressed air:
    Depending on the specific application, MOBILAIR portable compressors can also be equipped with microfilter combinations for technically oil-free compressed air, such as required for blasting applications as per German ZTV-ING regulations. This option delivers compressed air with an oil aerosol content of < 0.01 mg/m³, as per the requirements of ISO 8573-1.
  • pV control:
    The advantages of ‘pV control’ truly shine when it comes to cable blowing: initially, large volumes of air at lower pressure are used to accelerate the cable. Once in progress, more pressure and lower delivery volume are then used for long sections.

Simple and intuitive system control

SIGMA CONTROL MOBIL for portable compressors from KAESER KOMPRESSOREN.

The SIGMA CONTROL SMART controller assures exceptionally intuitive operation, since the compressor can be operated with just three buttons. Furthermore, the monitoring system can automatically shut the compressor down if necessary, or report required maintenance. The control panel is protected by a durable metal cover flap.

 

Our compressor powerhouses in detail

Infinitely variable pressure adjustment
Infinitely variable pressure adjustment
Manual wheel, as an example, for the M100.

On 10 to 14 bar versions, a manual wheel control fitted to the proportional controller enables infinite pressure adjustment for enhanced flexibility.

Setting variable pressure and flow rate
pV control directly influences the maximum possible flow rate (V) and therefore offers even greater variability in terms of pressure and flow rate.
  1. Breaker application
  2. Blasting application
  1. Cable blowing
  2. Drilling application

Maximum pressure (p) can be adjusted in steps of 0.1 bar between 5 and 15.5 bar. directly influences the maximum possible flow rate (V), thereby providing even greater flexibility in terms of both pressure and flow rate. This feature is particularly beneficial when working with longer hose lines.
