KAESER
Kaeser’s MOBILAIR range of portable air compressors is a dominant force in the global construction and industrial equipment landscape, known for combining German engineering excellence with rugged durability.
These mobile powerhouses are engineered to provide a reliable, efficient, and versatile source of compressed air for demanding applications ranging from road breaking and sandblasting to industrial maintenance and specialised site work.
Technology and Efficiency at the Core
The hallmark of the MOBILAIR line is its focus on efficiency. At the heart of every unit is Kaeser’s proprietary SIGMA Profile™ rotary screw airend. This optimised rotor design is a key differentiator, enabling the compressor to deliver significantly more air for less energy—reportedly up to 15-20% more air per gallon of fuel compared to conventional designs—contributing to lower fuel consumption and reduced operating costs.
Advanced control is managed by the SIGMA CONTROL SMART or MOBIL controllers, which ensure perfect coordination between the engine and the compressor package for optimal fuel efficiency and easy, intuitive operation.
