KAESER Mobile construction compressors – reliable and efficient to use

The KAESER brand stands for robust, reliable and efficient construction compressors. The product portfolio here covers ranges from 1 m³/min to oil-free units with 45 m³/min. The mobile units are suitable for a wide range of applications and are available with numerous options in mobile or stationary versions. Likewise, the construction compressors have a combustion engine or electric motor.

Accustomed to continuous operation, the units are particularly suitable for outdoor use in wind and weather thanks to robust polyethylene hoods. Easy handling and uncomplicated access to maintenance points allow service work to be carried out quickly and economically.

Environmental protection and less exhaust fumes – an approach that applies to all KAESER MOBILAIR. Thanks to special drive motors, the compressors meet the EU Stage V emissions standard. This is an environmental concept that KAESER lives by. Completely free of exhaust emissions, the electric, mobile units can be operated with a power connection nearby. Entry into environmental and noise protection zones can be realized without hesitation thanks to a quiet electric drive.

Mobilair M50B

Mobile compressed air with battery operation

At a time when electrification in drives is becoming increasingly important, the question of the usefulness of a battery-operated compressor and what such a solution could look like also arises in the field of construction compressors. KAESER Compressors is on the rise with a study here!

On the outside, the battery-powered M50B resembles a conventional construction compressor, but is significantly different on the inside. A 300 kilogram battery enables the compressor to be operated with wireless energy. The battery-powered machine is designed for the world’s most common compressor size of 5.2 m³/min (185cfm), with an operating pressure that can be set between 6 and 14 bar. The battery is sized so that it can cover the typical use of a construction compressor of this size on an average working day. These values were derived from experience with sister models that run on diesel and are in use worldwide.

KAESER’s study aims to introduce potential users to a wireless energy solution while questioning the needs and customer requirements in this area.

  • Where can users introduce the use of a battery-electric system and for which applications would it make sense?
  • What performance of the battery would be desirable and perhaps a hybrid solution would also be conceivable?

In this way, users can actively shape the future of construction compressors.

For the large projects

Powerful, stationary and absoutely suitable for outdoor use. There are the KAESER MOBILAR M250E and M255E construction compressors. Even when things get a little tight, the compact units can be set up without any problems. Transport by truck is child’s play – two e-power units fit in parallel on one truck bed. A solid carriage allows the unit to slide or be pulled at the installation side. The bodywork is protected from damage by the overhang of the carriage.

A star-delta start-up alows use ina temperature range of -10°C to +40°C. Low temperature versions with interior heating for ambient temperatures down to -25°C are also available.

The KAESER MOBILAIR M250E and M255E are delivered ready for connection with a switch disconnector. A terminal box or a POWERBLOCK plug is optionaly available for connection. A modem makes the compressors Industry 4.0 capable. Information about the technical condition of the plant, e.g. number of operting hours, location determination incl. geolashing can be obtained. Plant utilization, maintenance planning and remote diagnostics can thus be used without any problems.
