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 all the advantages of a two-stage oil-free compression rotary screw compressor with those of a portable unit: maximum compressed air delivery volumes and quality, coupled with unrivalled flexibility.

  • Compressed air aftercooler fitted as standard
  • Fleet Management via modem as standard
  • Optional skids version for stationary applications
  • Refinery equipment as standard – including certified spark arrester, engine shut-off valve and closed floor pan
  • Numerous features to facilitate set-up (chassis with parking brake, lifting and lashing eyes, forklift pockets)

The MOBILAIR M500-2 excels when operating in industrial applications. This compressed air titan is ideal for providing compressed air bridging operations when maintenance or repairs are required, for operating as a backup system when compressed air demand is high, or for refinery applications. Even automated production processes, such as connection to a control centre, pose no problem at all. The M500-2 can easily be controlled from there and integrated into any existing compressed air system. In the event of a drop in the compressed air supply, this oil-free compression rotary screw compressor jumps automatically to the rescue.

Performance data:

  • Flow rate up to 45.8 m³/min (1600 cfm)
  • Gauge working pressure up to 10.3 bar (150 psi)

Your benefits:

  • Environmentally friendly, today and for the future:
    Thanks to its state-of-the-art exhaust air treatment system, the dependable, low-emissions Caterpillar diesel engine integrated into the machine meets the stringent standards of EU Emissions Stage V.
  • Maximum, long-lasting efficiency:
    Due to an innovative special coating which remains resistant to temperatures of up to 300 °C, the blasted and phosphate-treated rotors exhibit no measurable trace of wear, even after years of operation.
  • Minimal downtime:
    Thanks to its generously sized fuel tank, the M500-2 can run throughout two consecutive shifts and, when connected to an external tank, can even run in continuous operation.
 

Our portable oil-free compression 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 optimises compressed 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

Remote diagnostics in real time

MOBILAIR fleet management

An optional GPS/GSM modem (standard on M500-2), discretely integrated into the unit, provides the user with online information regarding the technical status of the machine. In the event of a fault, the system actively reports it with a diagnostics check.
In addition to current operating hours and position-fixing, the system also assists by providing valuable data in relation to duty cycles and maintenance planning.
