HPC Mobilair M250

Portable Compressor With the world-renowned SIGMA PROFILE Flow rate 18.5 to 26.3 m³/min (655 – 930 cfm)

The perfect energy-saving combination: Caterpillar engine and KAESER airendThe powerful partnership of an energy-saving Caterpillar engine and the highly efficient KAESER SIGMA PROFILE rotary screw airend combines outstanding performance with considerably reduced fuel consumption. The MOBILAIR M200 can operate at full power for a whole shift without refuelling. Furthermore, users not only benefit from the quality of two world-class products, but can also rely on the comprehensive KAESER KOMPRESSOREN and Caterpillar global service networks to ensure maximum machine availability.

Exceptional versatility

The MOBILAIR M250 can be specifically tailored to meet the needs of the relevant application thanks to the wide range of optional compressed air treatment components available. Moreover, the selection of road and construction site chassis with run-on or compressed air brakes with ABS, as well as stationary models on skids or machine mounts, enables the M250 to be perfectly suited to meet the specific application's needs.

Tough performer

The M250 is well-equipped for continuous construction site duty under the harshest of conditions. Even the standard version is capable of operating in an ambient temperature range from -10° C to +50° C. The optional low-temperature version features engine coolant preheating, and synthetic cooling fluid is used for the airend. For the high altitude version, the SIGMA CONTROL MOBIL compressor controller automatically ensures reliable start up and operation regardless of whether the unit is operating at sea level or at 5500 m above sea level.

Low-emissions zone

The M250 is available as a Stage IIIA (Tier 3) compliant version which can be combined with the 3.5t chassis with run-on brake. For added versatility, another version is also available with a Mercedes-Benz drive engine certified in accordance with Stage IV (Tier 4 final), including a SCR catalytic converter and AdBlue technology

Simple to operate

Thanks to the SIGMA CONTROL MOBIL and intuitive operation, only three buttons are required to operate the compressor. Furthermore, the monitoring system can automatically shut the system down as required. The control panel is protected by a durable metal cover

Outstanding endurance

With a capacity of 250 or 350 litres of fuel depending on the selected chassis option, the two-part fuel tank can be filled from either side of the unit. All stationary versions come with a 350-litre on-board tank.
