Large compressors up to 34 m³/min (1200 cfm)

Steady marathoners with outstanding green credentials

Whether they are run as stand-alone units or grouped together: Our large compressors deliver top-quality compressed air with maximum availability – because they are designed for continuous operation. With state-of-the-art motor and control technologies, these compressors are extremely economical to run and very easy on the environment.

  • Maximum pressures up to 14 bar
  • Optional compressed air treatment
  • Various chassis and stationary design options
  • Optional GPS fleet management
  • Optional refinery accessories

Your advantages

  • Environmentally-friendly today and for the future:
    The advanced Mercedes-Benz diesel engine with SCR catalytic converter meets the European IIIB (M350) and IV (M250) emissions standard.
  • Power-saving fan:
    The demand-based variable speed fan control with Visco clutch generates up to 5% fuel savings.
  • Minimal downtime:
    The M250 and M350 can easily run for an entire shift without refuelling and keep maintenance time to a minimum.
Profitable thanks to low life-cycle costs

Our large compressors in detail


The compressor controller of the future


By accessing electronic motor management, the SIGMA CONTROL MOBIL system optimisescompressed 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 0.1 bar 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.

Optional features

Loading options

Recessed lifting eyes and forklift pockets make loading an easy operation.

Chassis options


The single-axle chassis are optionally available with an overrun brake or anti-lock (ABS) brake system.


Versions with tandem or steerable axles with parking brake are available for plant or construction site use.
The compressors can be fitted with a tandem axle with air brakes, including ABS and 24 V lighting, for towing on public roads.

Stationary versions

A robust skid provides a stable base for safe outdoor installation.
The stationary version can be fitted with adjustable machine feet for installation in buildings.

Sealed floor pan

The sealed floor pan immediately catches all liquids and therefore prevents potential soil contamination in environmentally sensitive zones.
The drainage holes are sealed with screwed sealing plugs.

Refinery use

A certified spark arrestor is available for refinery applications.
The engine shut-off valve automatically shuts the unit down upon intake of combustible gases.

MOBILAIR fleet management

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.
