Kaeser rolls out M122 compressor for on-site use

Kaeser has introduced its new Mobilair 122, which was exhibited earlier this year at Bauma 2007.

Kaeser has introduced its new Mobilair 122, which was exhibited earlier this year at Bauma 2007.

With a standard pressure range from 7-14 bar and a free-air delivery of 11.1m³/min at 7 bars, modern portable compressors should not only deliver exceptional performance and efficiency, but should also ensure simple operation and be environmentally sound.

The M122 is designed for large construction site applications such as sand and dry ice blasting, concrete repair and as a standby for stationary compressors. The compressor is powered by a water-cooled Deutz turbo-charged diesel engine with intercooler, which complies with all exhaust emissions as per EU regulation 2004/26, Class III A. Furthermore, the regulating system ensures optimum fuel economy, while the fuel tank capacity allows continuous operation for an entire eight-hour shift. The unit automatically shuts down if the fuel volume falls below the minimum level. Heavy-duty design allows the machine to be used at ambient temperatures of up to 50°C.

The M122 allows manual switchover from pressure-free start to full-load operation to ensure reliable compressor start-up even under cold conditions. For added flexibility, the 10, 12 and 14-bar versions enable infinitely variable pressure adjustment down to 5 bar via a manual wheel control on the proportional controller. As the M122 is equipped as standard with a 1,900kg chassis, a truck is not always required to tow the unit.

Instead of the standard towing chassis, the compressor is also available as a skid-mounted version. Optional additional equipment includes air treatment systems to provide cool, dry, technically oil-free air to meet the special demands of concrete repair, for example, as per German ZTV-SIB regulations, or air quality.
