The Mobilair 31 portable compressor from Kaeser

The Mobilair 31 portable compressor from Kaeser offers a scratch and corrosion resistant rotation-sintered polyethylene (PE) sound enclosure.

The screw airend with energy-saving Sigma Profile rotors is designed for continuous duty and is driven by a powerful, water-cooled Kubota turbo-diesel engine. Consequently, it provides a free air delivery of 3.15 m³/min at 7 bar – significantly more than previous models – which makes it suitable for simultaneously powering two 20 kg breakers, or other tools such as air lances, spaders, impact borers and sandblasting equipment.

7, 10, 12 and 14 bar versions of this easy to manoeuvre compressor are also available to meet a wide range of requirements. In addition, it can be equipped with an integrated aftercooler and centrifugal separator to provide a dependable supply of cool dry air and even a 6.5 kVA generator if required.

The Mobilair 31 models are fitted as standard with Kaeser’s patented Anti Frost Control, which protects air tools from potential damage caused by freezing and corrosion. In addition, the wide-opening soundproof enclosure allows quick and easy access to all maintenance points. Another useful option is the hose reel which comes with a 20 m lightweight hose, enabling the compressed air line to be safely stowed away instead of it becoming a potential trip hazard.

It is available with a 24.1 kW drive motor, standard working pressures 7, 10, 12 and 14 bar with free air deliveries from 1.9 to 3.15 m/3min. A stationary version is also available for specialised applications and can be easily installed on the cargo bed of a truck.
