Portable oil-free compression up to 45.8 m³/min (1600 cfm)


The new standard for the 50 cubic metre class

Our flagship M500-2 combines the advantages of a two-stage dry-running oil-free rotary screw compressor with those of a mobile unit: maximum compressed air capacity and quality with unrivalled flexibility.

  • Compressed air aftercooler fitted as standard
  • Fleet Management via GPS as standard
  • Refinery equipment as standard – including certified spark arrestor, engine shut-off valve and sealed floor pan.
  • Many features to facilitate setup (chassis with parking brake, crane and rigging eyelets, forklift pockets).

For industrial equipment with high compressed air requirements the M500-2 ensures continuity of compressed air supply even during maintenance or renovation work. Other areas of application include refineries – e.g. for pipeline flushing.
As a perfect team player, it easily integrates into existing stations.

Your advantages

  • Environmentally-friendly today and for the future:
    The reliable and low-emissions integrated Caterpillar diesel engine complies with Stage IV European emissions standards thanks to its integrated soot particle filter.
  • Maximum long-term efficiency:
    Thanks to an innovative coating that remains immune to temperatures up to 300 °C, the blasted and phosphate-treated rotors show no measurable wear even after years of use.
  • Minimal downtime:
    Thanks to its generously sized fuel tank, the M500-2 can run for two entire sequential shifts and can even run continuously when connected to an external tank.
Profitable thanks to low life-cycle costs
Life-cycle costs

Our comprehensive approach to optimal profitability: Optimal efficiency, easiest operation, service-friendliness and a global service and consulting network with fast response times.

 

Our portable dry-compression oil-free compressors in detail

SIGMA CONTROL MOBIL

The compressor controller of the future

SIGMA CONTROL MOBILE

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 settings

The system pressure can be set with precision of 0.1 bar directly on the SIGMA CONTROL MOBIL display using arrow keys, as can the compressed air discharge temperature; this enables precise adjustment to downstream compressed air treatment components.

Refinery equipment as standard

Sealed floor pan

The sealed floor pan for hazard areas immediately catches liquids to prevent any direct soiling of the floor or ground.
The drainage holes are sealed with screwed sealing plugs.

Spark arrestor

A certified spark arrestor is factory installed for use in areas at risk of explosion.

Shut-off valve

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.
