    MOBILAIR M 122

    The perfect energy-saving combination: Deutz engines and KAESER airends

    The powerful combination of an energy-saving Deutz engine and the highly effi cient KAESER SIGMA Profi le rotary screw airend combines outstanding performance with considerably reduced fuel consumption. The MOBILAIR M 122 can operate at full power for an entire shift without refuelling. The water-cooled Deutz engine complies with exhaust emission regulations and is certifi ed to Directive 2004/26/EC (Stage III A) and USA-

    EPA (TIER III). Furthermore, users not only benefi t from the quality of two world-class products, but can also rely on the comprehensive KAESER KOMPRESSOREN and Deutz global service networks to ensure maximum machine availability.

    For added fl exibility, a manual wheel control on the proportional controller enables infi nitely variable pressure adjustment.

    Dedicated intake fi lter for engine and airend

    Optimised design and separate air fi lters considerably enhance reli-ability and service life. The fi lters can be changed on-site quickly and easily as required.

    Easy to transport

    The M 122 features a fully galva-nised Alko chassis as standard. This not only ensures long-term value retention, but also makes transportation simple a truck is not required to tow the unit.

    Maximum versatility

    The Mobilair M 122 is in a class of its own when it comes to versatility, as it can be specifi cally tailored to meet the needsof the relevant application.

    Options include air treatment components, a choice of a fully galvanised chassis with overrun brake and a fi xed or height ad-justable tow bar, or stationary versions either mounted on skids or machine mountings.

    Made in Germany

    KAESERs renowned MOBILAIR range of portable compressors is manufactured in a state-of-the-art production facility located directly next to the KAESER main plant in Coburg, Northern Bavaria. Equipped with the very latest technology, the recently mod-ernised portable compressor plant boasts TV (German Technical Inspection Agency) certifi ed sound testing facilities for free-fi eld sound level measurement, an advanced powder coating installation and highly

    effi cient production logistics. With minimal turn-around time, KAESERs highly qualifi ed personnel are able to assemble portable compressors of all sizes and equipment levels to suit our customers specifi c needs.

    Superior power and fl exibility

  • MOBILAIR M 122 Large capacity, transparent fuel tank

    When fully fi lled, the tank carries suffi cient fuel for an entire work shift without the need for refuelling. For ease of operation, an automatic shutdown feature is activated when the fuel level becomes too low.

    Tool storage space

    The integrated tool box provides generous storage space for all tools and accesso-ries. A second tool box is also optionally available.

    Large gull-wing doors

    The M 122's user-friendly design not only ensures simple operation and outstanding manoeuvrability: the unit's large gull-wing doors also provide excellent component accessibility for unrivalled ease of mainte-nance.

    Thermostatic valve for oil temperature regulation

    The M 122s automatically controlled thermostatic valve ensures that optimal operating temperature is reached quickly and reliably. It therefore protects the compressors fl uid circulation loop from excessive condensate accumulation. This in turn signifi cantly extends cooling fl uid and separator cartridge service life and also enhances the unit's long-term durability.

    Easy to operate

    The user-friendly control and instrument panel, which can be equipped with a cover

    fl ap if required, enables all information to be viewed at a glance. Features also include

    automatic monitoring and shutdown. Manual switchover from idling to full load operation

    ensures a reliable, gentle start when operat-ing the unit in cold ambient conditions.

    Cool, clean air

    The compressed air is cooled to 7 C above ambient temperature. Accumulated condensate is able to drain away easily, as the com-

    pressed air cooler is installed at an angle, whilst the hot exhaust gasses from the engine are also used to aid

    condensate evaporation. This de-sign consequently ensures reliable

    frost prevention during the winter months.

    Filter combination

    Additional air treatment components need to be installed downstream from the after-cooler and centrifugal separator (e.g. fi lter combina-

    tions for concrete cleaning as per ZTV-ING) in order to achieve compressed air of a spec-

    ifi ed quality class. The differential pressure indicator enables fi lter status to be monitored

    quickly and easily.

    Ambient temperature

    Standard units are rated for ambient temper-atures between -10 and +50 C. A version

    for lower ambient temperatures is also available.
