M255: 900 cfm portable compressor


M255 Mobilair Compressor

Kaeser’s M255 portable diesel compressor features variable pressures for exceptional jobsite flexibility and easy operation with the new SIGMA CONTROL MOBIL 2. Delivering up to 900 cfm, it is built for the big jobs, but weighs in under 8,000 lb and can be safely towed with a pick-up truck. The steel chassis, torsion bar suspension, oversized tires, and lighting package ensure easy portability, safety, and excellent road handling, while the high capacity, cold start battery assures year round reliability. 

The M255 has two pressure ranges:  

  • 848-935 cfm at 125-150 psig and 
  • 696-900 cfm at 125-203 psig. 
This powerful unit is perfect for heavy duty construction, utility and demolition uses and is designed for maximum flexibility and reliability on site.  

The M255 is the first Mobilair to feature the new Sigma Control Mobil 2 with intuitive touch screen control and real time operational data. 

Kaeser’s exclusive pV Control is standard and can adjust the unit pressure in 1 psi increments. This intelligent controller optimizes compressed air availability and fuel efficiency with our Sigma Profile airend. 

The 6-cylinder Cummins diesel engine meets Tier 4 Final emission standards and includes both a diesel particulate filter and an SCR catalytic converter. 

The M255 has great road handling and is easily towed on the road and at the jobsite with a half-ton pick-up. Kaeser’s service friendly design, including wide-opening gull wing doors, spin-on filter cartridges, and easy-filling port access make routine maintenance a breeze.
