HPC Mobilair M81/M82

Portable Compressors With the world-renowned SIGMA PROFILE Flow rate 5.5 to 8.4 m³/min (195 – 295 cfm)

The powerful combination of the highly efficient KAESER SIGMA PROFILE rotary screw airend and an energy-saving Kubota engine equipped with a diesel particulate filter as standard provides impressive fuel efficiency and super-clean performance.


The MOBILAIR M81/M82 can be specifically tailored to meet the needs of the relevant application thanks to the wide range of optional compressed air treatment components. Moreover, the selection of chassis with run-on brake, as well as stationary models on skids or machine mountings, enables the M81/M82 to be perfectly adapted to suit the specific work environment.

Safe and simple

The ability to switch over manually from idling to full load operation ensures a reliable, gentle start when operating the unit in cold ambient conditions. Furthermore, the monitoring system can automatically shut the compressor down if necessary


The M81/M82 is well-equipped for continuous gruelling construction site duty under the harshest of conditions. Even the standard versions are capable of operating in an ambient temperature range from -10°C to +45°C. The optional low-temperature versions feature engine coolant preheating, and synthetic cooling fluid is used for the airend.

M82: Generator option

The optional synchronous three-phase generator (IP 54) is available with a power of 8.5 or 13 kVa. According to power requirement, the brushless and maintenance-free generator can be switched over from continuous operation to energy-saving automatic start. If required, the generator control panel can be equipped with a lockable cover.

Excellent accessibility, optimum serviceability

Thanks to intelligent component layout, all maintenance points are easily accessible via the large gull-wing doors, which makes service work fast and efficient. Optional custom service contracts are also available.
